I am trying to print the list of title and dob in the xml file. But I can not find the error in the code.Here I am trying this to understand exactly how parameters work in xsl
here is the xml code
<?xml-stylesheet type="text/xsl" href="aa.xslt"?>
<tutorial>

Here is the xslt code
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

<div>
NAME: <xsl:value-of select="$myname" />
<br />
DOB: <xsl:value-of select="$mydob" />
<hr />
</div>
</xsl:template>
</xsl:stylesheet>
expecting output is,
Introduction1

and etc.
It looks like you're trying to output the title of panel, so try changing:
<xsl:template match="tutorial/section">
to:
<xsl:template match="tutorial/section/panel">
Edit
If you're having issues with "Not Available" showing up, it's because you are passing the parameter an empty string when the element doesn't exist and it overwrites the default value.
You could do something like:
<xsl:template match="tutorial/section/panel">
<xsl:call-template name="boo">
<xsl:with-param name="myname">
<xsl:choose>
<xsl:when test="title">
<xsl:value-of select="title"/>
</xsl:when>
<xsl:otherwise>Not Available</xsl:otherwise>
</xsl:choose>
</xsl:with-param>
<xsl:with-param name="mydob">
<xsl:choose>
<xsl:when test="dob">
<xsl:value-of select="dob"/>
</xsl:when>
<xsl:otherwise>Not Available</xsl:otherwise>
</xsl:choose>
</xsl:with-param>
</xsl:call-template>
</xsl:template>
or something like this:
<xsl:template match="tutorial/section/panel">
<xsl:choose>
<xsl:when test="title and dob">
<xsl:call-template name="boo">
<xsl:with-param name="myname" select="title" />
<xsl:with-param name="mydob" select="dob" />
</xsl:call-template>
</xsl:when>
<xsl:when test="dob">
<xsl:call-template name="boo">
<xsl:with-param name="mydob" select="dob" />
</xsl:call-template>
</xsl:when>
<xsl:when test="title">
<xsl:call-template name="boo">
<xsl:with-param name="myname" select="title" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:call-template name="boo"/>
</xsl:otherwise>
</xsl:choose>

I would like to tokenize string with a word.
I am using str:tokenize() but it seems that delimiter might be only single char, even the delimiter consist of more characters, the tokenize() does search for listed characters in the delimiter.
E.g.
InputString : "first|second|third|##|First|Second|Third
Delimiter : |##|
str:tokenize(&InputString, '|##|')
but this returns 6 rows instead of 2
I need to have it in for-each due to next operations with tokenized "sentences"
What am I doing wrong with str:tokenize() ?
The result you get is conforming to the specification for the str:tokenize function:
The second argument is a string consisting of a number of characters.
Each character in this string is taken as a delimiting character. The
string given by the first argument is split at any occurrence of any
of these characters.
What you want to do is split the given string at any occurrence of a given pattern instead. For this, you need to use the str:split function - if your processor supports it.
thx for advise.
I am attaching example code which match my needs- may be it would help someone to save his/her time.
It takes element and parse it according to two delimiters, plus it draws all cells (including empty one - even last one is empty). If the second cell/column is empty it will skip whole row.

screenshot of Output vs XML
I am quite new to XSLT,
I have a source XML message, which in its simplified version looks something like this:
<?xml version='1.0' encoding='iso-8859-1'?>
<Message>
<Invalid>
<InvalidBody>
<SynchError>
<ErrorText>The value of %1 should not be %2.</ErrorText>
<ErrorParameter>
<!-- Error Parameter is %1 identifier -->
<ErrorParameterType>value</ErrorParameterType>
<ErrorParameterValue>someField</ErrorParameterValue>
</ErrorParameter>
<ErrorParameter>
<!-- Error Parameter is %2 identifier -->
<ErrorParameterType>value</ErrorParameterType>
<ErrorParameterValue>someValue</ErrorParameterValue>
</ErrorParameter>
</SynchError>
</InvalidBody>
</Invalid>
</Message>
Now, I would like to use XSLT 1.0 to extract the ErrorText string and substitute the parameters %1 and %2 with the corresponding ErrorParameter/ErrorParameterValue values. The number of parameters %1, %2, %3... cannot be known in advance, so the solution should be flexible enough to accommodate a variable number of parameters.
Is there any elegant way to do this?
So, after quite a lot of googling around and a healthy dose of headache, I came up with the following solution, which seems to work like a charm:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/">
<xsl:variable name="err-text" select="/Message/Invalid/InvalidBody/SynchError/ErrorText" />
<xsl:variable name="param-count" select="count(/Message/Invalid/InvalidBody/SynchError/ErrorParameter)" />
<xsl:call-template name="replace-params">
<xsl:with-param name="position" select="$param-count"/>
<xsl:with-param name="source-text" select="$err-text" />
</xsl:call-template>
</xsl:template>
<xsl:template name="replace-params">
<xsl:param name="position"/>
<xsl:param name="source-text"/>
<xsl:choose>
<xsl:when test="$position = 0">
<xsl:value-of select="$source-text"/>
</xsl:when>
<xsl:otherwise>
<xsl:call-template name="replace-params">
<xsl:with-param name="position" select="$position - 1"/>
<xsl:with-param name="source-text">
<xsl:call-template name="string-replace-all">
<xsl:with-param name="text" select="$source-text" />
<xsl:with-param name="replace" select="concat('%', $position)" />
<xsl:with-param name="by" select="/Message/Invalid/InvalidBody/SynchError/ErrorParameter[$position]/ErrorParameterValue" />
</xsl:call-template>
</xsl:with-param>
</xsl:call-template>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template name="string-replace-all">
<xsl:param name="text" />
<xsl:param name="replace" />
<xsl:param name="by" />
<xsl:choose>
<xsl:when test="contains($text, $replace)">
<xsl:value-of select="substring-before($text,$replace)" />
<xsl:value-of select="$by" />
<xsl:call-template name="string-replace-all">
<xsl:with-param name="text"
select="substring-after($text,$replace)" />
<xsl:with-param name="replace" select="$replace" />
<xsl:with-param name="by" select="$by" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$text" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
I use the "string-replace-all" template as a substitute for the XSLT 2.0 replace() function, since I cannot exclude multiple occurrences of a single parameter.
The "replace-params" template is applied recursively on the original text, iterating backwards on the index of the set of ErrorParameters.
The way I have tackled similar problems is to create a named template that recurses through the string (text element of) <ErrorText> with each cycle picking out the first n% item, then dereferences the <ErrorParameter> to access the contents of that and store in a result, then snip off the n% item just process and calls itself to grab the next one. When there are no more %n items left, return the result.
Here's an example of that, this template basically counts comma-separated items in a parameter passed in on the first cycle called List, and returns a $Count when it's finished.
<xsl:template name="CountList">
<xsl:param name="List"/>
<xsl:param name="Count" select="0"/>
<xsl:choose>
<xsl:when test="contains($List,',') = false()">
<xsl:value-of select="$Count"/>
</xsl:when>
<xsl:otherwise>
<xsl:call-template name="CountList">
<xsl:with-param name="List">
<xsl:value-of select="substring-after($List,',')"/>
</xsl:with-param>
<xsl:with-param name="Count">
<xsl:value-of select="$Count + 1"/>
</xsl:with-param>
</xsl:call-template>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
You can try something like this. You can use a replace instead of 'substring-before' and 'after' if this function is supported.
<xsl:template match="SynchError">
<xsl:apply-templates select="ErrorParameter[1]">
<xsl:with-param name="text"><xsl:value-of select="ErrorText"/></xsl:with-param>
<xsl:with-param name="position">1</xsl:with-param>
</xsl:apply-templates>
</xsl:template>
<xsl:template match="ErrorParameter">
<xsl:param name="text"/>
<xsl:param name="position"/>
<xsl:apply-templates select="following::ErrorParameter">
<xsl:with-param name="position"><xsl:value-of select="number($position)+1"/></xsl:with-param>
<xsl:with-param name="text"><xsl:value-of select="concat(substring-before($text,concat('%',$position)),ErrorParameterValue,substring-after($text,concat('%',$position)))"/></xsl:with-param>
</xsl:apply-templates>
<xsl:if test="not(following::ErrorParameter)">
<xsl:value-of select="concat(substring-before($text,concat('%',$position)),ErrorParameterValue,substring-after($text,concat('%',$position)))"/>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
Here's another way you could look at it:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
<output>
<xsl:call-template name="merge">
<xsl:with-param name="string" select="Message/Invalid/InvalidBody/SynchError/ErrorText"/>
<xsl:with-param name="parameters" select="Message/Invalid/InvalidBody/SynchError/ErrorParameter"/>
</xsl:call-template>
</output>
</xsl:template>
<xsl:template name="merge">
<xsl:param name="string"/>
<xsl:param name="parameters"/>
<xsl:param name="flag" select="'%'"/>
<xsl:choose>
<xsl:when test="contains($string, $flag)">
<xsl:variable name="subsequent-char"
select="substring(translate(substring-after($string, $flag), '0123456789', ''), 1, 1)"/>
<xsl:variable name="i"
select="substring-before(substring-after($string, $flag), $subsequent-char)" />
<xsl:value-of select="substring-before($string, $flag)"/>
<xsl:value-of select="$parameters[number($i)]/ErrorParameterValue"/>
<!-- recursive call -->
<xsl:call-template name="merge">
<xsl:with-param name="string" select="substring-after($string, concat($flag, $i))"/>
<xsl:with-param name="parameters" select="$parameters"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$string"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
Given XML of:
<data>
<field>Value 1
Value 2
Value 3
</field>
</data>
I would like to be able to create some HTML to display the values and convert the
into <br/>
<html>
<head/>
<body>
<div>Field Values</div>
<div>Value 1<br/>Value 2<br/>Value 3<br/></div>
</body>
</html>
However I can't think of way to do this using XSL version 1.0?
I tried
<xsl:value-of select="field" disable-output-escaping="yes"/>
However the text all appears on 1 line.
Any ideas/suggestions?
Thanks
Dave
You can use a recursive template do do the replacement:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
<data>
<xsl:call-template name="replaceCharsInString">
<xsl:with-param name="stringIn" select="data/field" />
</xsl:call-template>
</data>
</xsl:template>
<xsl:template name="replaceCharsInString">
<xsl:param name="stringIn"/>
<xsl:choose>
<xsl:when test="contains($stringIn,'
')">
<xsl:value-of select="substring-before($stringIn,'
')"/>
<br />
<xsl:call-template name="replaceCharsInString">
<xsl:with-param name="stringIn"
select="substring-after($stringIn,'
')"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$stringIn"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
Here is how you can replace
with <br/>:
<xsl:template match="data">
<xsl:call-template name="add-br">
<xsl:with-param name="text" select="field" />
</xsl:call-template>
</xsl:template>
<xsl:template name="add-br">
<xsl:param name="text" select="."/>
<xsl:choose>
<xsl:when test="contains($text, '
')">
<xsl:value-of select="substring-before($text, '
')"/>
<br/>
<xsl:call-template name="add-br">
<xsl:with-param name="text" select="substring-after($text,'
')"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$text"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
I'm transforming XML to an HTML document. In this document I want to embed XML markup for a node that was just transformed (the HTML document is a technical spec).
For example, if my XML was this:
<transform-me>
<node id="1">
<stuff type="floatsam">
<details>Various bits</details>
</stuff>
</node>
</transform-me>
I'd want my XSLT output to look something like this:
<h1>Node 1</h1>
<h2>Stuff (floatsam)</h2>
Various bits
<h2>The XML</h2>
<stuff type="floatsam">
<details>Various bits</details>
</stuff>
I'm hoping there is an XSLT function that I can call in my <stuff> template to which I can pass the current node (.) and get back escaped XML markup for <stuff> and all its descendants. I have a feeling unparsed-text() might be the way to go but can't get it to work.
Very simple template
<xsl:template match="node()" mode="print">
<xsl:choose>
<!-- is it element? -->
<xsl:when test="name()">
<!-- start tag -->
<xsl:text><</xsl:text>
<xsl:value-of select="name()" />
<!-- attributes -->
<xsl:apply-templates select="#*" mode="print" />
<xsl:choose>
<!-- has children -->
<xsl:when test="node()">
<!-- closing bracket -->
<xsl:text>></xsl:text>
<!-- children -->
<xsl:apply-templates mode="print" />
<!-- end tag -->
<xsl:text></</xsl:text>
<xsl:value-of select="name()" />
<xsl:text>></xsl:text>
</xsl:when>
<!-- is empty -->
<xsl:otherwise>
<!-- closing bracket -->
<xsl:text>/></xsl:text>
</xsl:otherwise>
</xsl:choose>
</xsl:when>
<!-- text -->
<xsl:otherwise>
<xsl:copy />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template match="#*" mode="print">
<xsl:text> </xsl:text>
<xsl:value-of select="name()" />
<xsl:text>="</xsl:text>
<xsl:value-of select="." />
<xsl:text>"</xsl:text>
</xsl:template>
Used
<xsl:apply-templates mode="print" />
You can even add pretty printing if you want.
The answer to this is more complex that you would at first think. Proper "double-escaping" of attribute values and text nodes must occur.
This XSLT 1.0 template does a correct (though not complete) printing of an XML node, including (an attempt to do) proper pretty-printing with configurable indentation:
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>
<xsl:output method="html" encoding="utf-8" />
<!-- defaults and configurable parameters -->
<xsl:param name="NL" select="'
'" /><!-- newline sequence -->
<xsl:param name="INDENTSEQ" select="' '" /><!-- indent sequence -->
<xsl:variable name="LT" select="'<'" />
<xsl:variable name="GT" select="'>'" />
<xsl:template match="transform-me">
<html>
<body>
<!-- this XML-escapes an entire sub-structure -->
<pre><xsl:apply-templates select="*" mode="XmlEscape" /></pre>
</body>
</html>
</xsl:template>
<!-- element nodes will be handled here, incl. proper indenting -->
<xsl:template match="*" mode="XmlEscape">
<xsl:param name="indent" select="''" />
<xsl:value-of select="concat($indent, $LT, name())" />
<xsl:apply-templates select="#*" mode="XmlEscape" />

When applied to this test XML:
<transform-me>
<node id="1">
<!-- a comment -->
<stuff type="fl"'
oatsam">
<details>Various bits & pieces</details>
<details>
</details>
<details attr="value">
<childnode>text and <escaped-text /></childnode>
</details>
</stuff>
</node>
</transform-me>
The following output is produced (source code):
<html>
<body>
<pre><node id="1">
<!-- a comment -->
<stuff type="fl"'
	oatsam">
<details>Various bits & pieces</details>
<details />
<details attr="value">
<childnode>text and <escaped-text /<</childnode>
</details>
</stuff>
</node>
</pre>
</body>
</html>
and when viewed in the browser you see:
<node id="1">
<!-- a comment -->
<stuff type="fl"'
oatsam">
<details>Various bits & pieces</details>
<details />
<details attr="value">
<childnode>text and <escaped-text /<</childnode>
</details>
</stuff>
</node>
Note that by "not complete" I mean that things like namespaces and processing instructions for example are currently unhandled. But its easy to make a template for them.
I need to check if a particular string contains a a particular word for example to check if,
SultansOfSwing contains the word Swing.
Let me also mention that the value of the string in question is unknown. As in it can be any word so we do not know the length et cetera.
I understand I can do this by using the contains keyword.
But once I know that this word contains the Swing keyword I want to display the string without this "Swing" word.. thus effectively displaying only "SultansOf".
I have been trying to explore how I can achieve this but not getting any break through.
Could somebody please advise which keyword or function will provide this facility ? How can I remove a particular word from within a string.
Given this for input:
<root>
<song>SultansOfSwing</song>
<song>SwingOfSultans</song>
<song>SultansSwingOf</song>
</root>
The output of this:
<?xml version='1.0' ?>
<root>
<swing-less-long>SultansOf</swing-less-long>
<swing-less-long>OfSultans</swing-less-long>
<swing-less-long>SultansOf</swing-less-long>
</root>
Can be gotten from this. Note the use of substring-before and substring-after.
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes"/>
<xsl:template match="/">
<root>
<xsl:apply-templates select="root/song"/>
</root>
</xsl:template>
<xsl:template match="song">
<swing-less-long>
<xsl:if test="contains(., 'Swing')">
<xsl:call-template name="remove">
<xsl:with-param name="value" select="."/>
</xsl:call-template>
</xsl:if>
</swing-less-long>
</xsl:template>
<xsl:template name="remove">
<xsl:param name="value"/>
<xsl:value-of select="concat(substring-before($value, 'Swing'), substring-after($value, 'Swing'))"/>
</xsl:template>
</xsl:stylesheet>
I think this string replacement function is quite exhaustive:
EDIT - needed to change $string to $string2. Should work now
<xsl:template name="string-replace">
<xsl:param name="string1" select="''" />
<xsl:param name="string2" select="''" />
<xsl:param name="replacement" select="''" />
<xsl:param name="global" select="true()" />
<xsl:choose>
<xsl:when test="contains($string1, $string2)">
<xsl:value-of select="substring-before($string1, $string2)" />
<xsl:value-of select="$replacement" />
<xsl:variable name="rest" select="substring-after($string1, $string2)" />
<xsl:choose>
<xsl:when test="$global">
<xsl:call-template name="string-replace">
<xsl:with-param name="string1" select="$rest" />
<xsl:with-param name="string2" select="$string2" />
<xsl:with-param name="replacement" select="$replacement" />
<xsl:with-param name="global" select="$global" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$rest" />
</xsl:otherwise>
</xsl:choose>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$string1" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
It's case-sensitive, mind you. In your case:
<xsl:call-template name="string-replace">
<xsl:with-param name="string1" select="'SultansOfSwing'" />
<xsl:with-param name="string2" select="'Swing'" />
<xsl:with-param name="replacement" select="''" />
</xsl:call-template>
