XSLT problem concerning call-template & with-param - xslt

I'm banging my head against the wall trying to figure out why this won't work:
<xsl:call-template name="test-template">
<xsl:with-param name="item" select="WTF" />
</xsl:call-template>
<xsl:template name="test-template">
<xsl:param name="item" />
-~<xsl:value-of select="$item" />~-
</xsl:template>
Output is: -~~- when what I want is -~WTF~-

First of all, as RonK said, your parameter names should match.
Also, if you want to pass the value "WTF" (instead of XML node "WTF"), you've to single-quote it:
<xsl:call-template name="test-template">
<xsl:with-param name="item" select="'WTF'" />
</xsl:call-template>
<xsl:template name="test-template">
<xsl:param name="item" />
-~<xsl:value-of select="$item" />~-
</xsl:template>

I haven't touched XSLT for quite some time - but I think your parameter names should match. Meaning:
<xsl:call-template name="test-template">
<xsl:with-param name="is-item-page" select="WTF" />
</xsl:call-template>
<xsl:template name="test-template">
<xsl:param name="is-item-page" />
-~<xsl:value-of select="$item" />~-
</xsl:template>
Try it.

XSLT: Using following-sibling on an array of strings?

Having tokenized an attribute containing a file path (e.g. /dir1/dir2/dir3), I now have an array (or node set?) of strings.
I would like to recursively process the first item and pass the rest on - and had hoped to accomplish this using the 'following-sibling' axis. However, it turns out that it expects actual elements and not merely strings.
<xsl:template match="s:universe">
<xsl:call-template name="createSubFolder">
<xsl:with-param name="folderNames" select="tokenize(#path, '/')" />
</xsl:call-template>
</xsl:template>
<xsl:template name="createSubFolder">
<xsl:param name="folderNames" />
<xsl:if test="count($folderNames) > 0">
<folder>
<xsl:attribute name="name" select="$folderNames[1]" />
<xsl:if test="position() < count($folderNames)">
<folder>
<xsl:call-template name="createSubFolder">
<xsl:with-param name="folderNames" select="$folderNames[1]/following-sibling::text()" />
</xsl:call-template>
</folder>
</xsl:if>
</folder>
</xsl:if>
</xsl:template>
The only solution I currently imagine would be creating a custom function which feeds the tail end of an array to the template - but I have the feeling that there could/must be a better way.
As Martin Honnen mentioned in the comments, tokenize(#path, '/') returns sequence of string(s). So you cannot use following-sibling axis to the string type.
You can use subsequence($folderNames,2) or $folderNames[position() gt 1] to use recursive call like following:
<xsl:template name="createSubFolder">
<xsl:param name="folderNames" as="xs:string*"/>
<xsl:if test="exists(($folderNames[1]))">
<folder>
<xsl:attribute name="name" select="$folderNames[1]" />
<xsl:call-template name="createSubFolder">
<xsl:with-param name="folderNames" select="subsequence($folderNames,2)"/>
</xsl:call-template>
</folder>
</xsl:if>
</xsl:template>

Sum of attributes after truncating a character from the value

I have the following xml.
<xml>
<table>
<cols width="1.00*" />
<cols width="2.00*" />
<cols width="4.00*" />
<row><p>Hello</p></row>
</table>
<p>
Life is good.
</p>
</xml>
Explaination:
I need to read the column width from the above xml and display. But in some cases user specifies the width so less that the table columns overlap on each other.
Hence I thought to do this formula.
col1width=col1width/totalWidth*100;
This will give me the table width in % format so that the columns get distributed properly.
But I am not able to take a total count of all these attributes. My xslt just does not work. Please see the xslt below:
XSLT:
<xsl:template match="node()" mode="table">
<fo:table table-layout="fixed">
<fo:table-header>
<fo:table-row>
<xsl:for-each select="current()/cols">
<xsl:variable name="maxWidth"
select="number(substring-before(current()/table/cols/#width, '*')) + number(substring-before(following-sibling::cols/#width, '*'))" />
</xsl:for-each>
</fo:table-row>
</fo:table>
Solutions tried:
I have tried using sum function. But here, before summing, i have to
truncate the '*' character and convert to number and then add. Does
not work.
Written a recursive template to get the sum. I am getting the sum with this. But I am not able to return the total width from the
template. I guess xslt does not support returning of calculated
values. Below is the recursive xslt.
<xsl:template name="maximumTableWidth">
<xsl:param name="total" select="0" />
<xsl:param name="totalCols" />
<xsl:param name="index" select="1" />
<xsl:if test="$index <= $totalCols">
<xsl:variable name="maxWidth"
select="$total + translate(current()/cols[$index]/#width, '*', '')" />
<xsl:call-template name="maximumTableWidth">
<xsl:with-param name="total" select="$maxWidth" />
<xsl:with-param name="nodes" select="$totalCols" />
<xsl:with-param name="index" select="$index + 1" />
</xsl:call-template>
</xsl:if>
</xsl:template>
XSLT call:
<xsl:template name="main">
<xsl:variable name="maximumWidth">
<xsl:call-template name="maximumTableWidth">
<xsl:with-param name="total" select="0" />
<xsl:with-param name="totalCols"
select="count(current()/cols)" />
</xsl:call-template>
</xsl:variable>
</xsl:template>
Here, the variable is of type string and hence has no value.
Please help me with this problem. Also can suggest any other approach for table column width. I am generating pdf output using xsl fo. And my whole xslt is dynamic. I cannot have a direct path like node1/node2/node3.
Thank you.
You've got a couple of problems with your maximumTableWidth template to start with. Firstly, you should probably wrap the translate function in the number function
<xsl:variable name="maxWidth"
select="$total + number(translate(current()/cols[$index]/#width, '*', ''))" />
Secondly, you need to make sure you call it with the correct parameters. For your recursive call you set a parameter called nodes, when it should be totalCols
<xsl:with-param name="totalCols" select="$totalCols" />
But in terms of returning a value, all you need to do it use xsl:value-of to output the value, and your maximumWidth variable will then be set to that value. All you need to do is change the xsl:if in the template to an xsl:choose and output the value in the xsl:otherwise condition:
<xsl:template name="maximumTableWidth">
<xsl:param name="total" select="0" />
<xsl:param name="totalCols" />
<xsl:param name="index" select="1" />
<xsl:choose>
<xsl:when test="$index <= $totalCols">
<xsl:variable name="maxWidth"
select="$total + number(translate(current()/cols[$index]/#width, '*', ''))" />
<xsl:call-template name="maximumTableWidth">
<xsl:with-param name="total" select="$maxWidth" />
<xsl:with-param name="totalCols" select="$totalCols" />
<xsl:with-param name="index" select="$index + 1" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$total" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
There is another way to write this template recursively. Instead of passing in the index, and incrementing it, pass in the cols element itself, and use following-sibling to iterate over them. Try this template instead
<xsl:template name="maximumTableWidth">
<xsl:param name="col" />
<xsl:param name="total" select="0" />
<xsl:choose>
<xsl:when test="$col">
<xsl:variable name="maxWidth"
select="$total + number(translate($col/#width, '*', ''))" />
<xsl:call-template name="maximumTableWidth">
<xsl:with-param name="total" select="$maxWidth" />
<xsl:with-param name="col" select="$col/following-sibling::cols[1]" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$total" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
You would call this like so:
<xsl:variable name="maximumWidth">
<xsl:call-template name="maximumTableWidth">
<xsl:with-param name="col" select="cols[1]" />
</xsl:call-template>
</xsl:variable>
<xsl:value-of select="$maximumWidth" />
EDIT: If you were able to use XSLT 2.0, then you can do away with the named template altogether, and just set the maximumWidth template to this
<xsl:variable name="maximumWidth" select="sum(cols/(number(translate(#width, '*', ''))))" />

XSL call template with dynamic nodes

Hello i need to achieve the below functionality in my XSL but it seems i'm stuck... Any help will be much appreciated.
Please see my comments inside the below code snippet.
<xsl:template name="/">
<xsl:call-template name="looptemplate">
<xsl:with-param name="x" select="1"/>
<xsl:with-param name="max" select="10"/>
</xsl:call-template>
</xsl:template>
<xsl:template name=" looptemplate">
<xsl:param name="x"/>
<xsl:param name="max"/>
<xsl:call-template name="TemplateToCall">
<xsl:with-param name="nodePath" select="a/b$i"></xsl:with-param>
<!--
Get dynamically root nodes
a/b1, a/b2, a/b3 etc
-->
</xsl:call-template>
<!--
Loop again until x reaches max
-->
</xsl:template>
<xsl:template name="TemplateToCall">
<xsl:param name="nodePath"/>
<xsl:for-each select="$nodePath">
<xsl:value-of select="value1"/>, <xsl:value-of select="value2"/>
</xsl:for-each>
</xsl:template>
You can't build an XPath as a string and evaluate it dynamically like that (at least not in plain XSLT 1.0 or 2.0, there will be an xsl:evaluate instruction in XSLT 3.0), but you could do something like
<xsl:call-template name="TemplateToCall">
<xsl:with-param name="nodes" select="a/*[local-name() = concat('b', $i)]"/>
and then in the called template
<xsl:template name="TemplateToCall">
<xsl:param name="nodes"/>
<xsl:for-each select="$nodes">

XSL - Removing the filename from the path string

I've got a SharePoint problem which I need some help with. I'm creating some custom ItemStyles to format the output of a Content Query Webpart (CQWP) but I need to insert a "view all" button into the output.
View all needs to point to:
http://www.site.com/subsite/doclibrary1/Forms/AllItems.aspx
All the individual files in the document library have the link of:
http://www.site.com/subsite/doclibrary1/FileName.doc
So what I need is some XSL functions to strip FileName.doc from the end of the string.
I've tried using substring-before($variable, '.') to get rid of the .doc, but I then need to find a way to use substring-after to search for the LAST forward slash in the series and truncate the orphaned filename.
Using #Mads Hansen's post, this is the code which resolved the problem:
Template in ItemStyle.xsl
<xsl:template name="ImpDocs" match="Row[#Style='ImpDocs']" mode="itemstyle">
<xsl:variable name="SafeLinkUrl">
<xsl:call-template name="OuterTemplate.GetSafeLink">
<xsl:with-param name="UrlColumnName" select="'LinkUrl'"/>
</xsl:call-template>
</xsl:variable>
<xsl:variable name="ViewAllLink">
<xsl:call-template name="OuterTemplate.getCleanURL">
<xsl:with-param name="path" select="#LinkUrl"/>
</xsl:call-template>
</xsl:variable>
<div class="DocViewAll">
View All
<!--Any other code you need for your custom ItemStyle here-->
</div>
</xsl:template>
Template in ContentQueryMain.xsl
<xsl:template name="OuterTemplate.getCleanURL">
<xsl:param name="path" />
<xsl:choose>
<xsl:when test="contains($path,'/')">
<xsl:value-of select="substring-before($path,'/')" />
<xsl:text>/</xsl:text>
<xsl:call-template name="OuterTemplate.getCleanURL">
<xsl:with-param name="path" select="substring-after($path,'/')" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise />
</xsl:choose>
</xsl:template>
Executing this stylesheet produces: http://www.site.com/subsite/doclibrary1/
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:template match="/">
<xsl:call-template name="getURL">
<xsl:with-param name="path">http://www.site.com/subsite/doclibrary1/FileName.doc</xsl:with-param>
</xsl:call-template>
</xsl:template>
<xsl:template name="getURL">
<xsl:param name="path" />
<xsl:choose>
<xsl:when test="contains($path,'/')">
<xsl:value-of select="substring-before($path,'/')" />
<xsl:text>/</xsl:text>
<xsl:call-template name="getURL">
<xsl:with-param name="path" select="substring-after($path,'/')" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise />
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
The getURL template makes a recursive call to itself when there are "/" characters in the string. While there are still "/" characters, it spits out the values before the slash, and then invokes itself. When it reaches the last one, it stops.
The given solutions are not able to handle url's without filename and extension at the end (Path to folder)
I changed the ideas above to include this aswell...
<xsl:template name="getPath">
<xsl:param name="url" />
<xsl:choose>
<xsl:when test="contains($url,'/')">
<xsl:value-of select="substring-before($url,'/')" />
<xsl:text>/</xsl:text>
<xsl:call-template name="getPath">
<xsl:with-param name="url" select="substring-after($url,'/')" />
</xsl:call-template>
</xsl:when >
<xsl:otherwise>
<xsl:if test="not(contains($url,'.'))">
<xsl:value-of select="$url" />
</xsl:if>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
Btw. Why does MS still not support XSLT 2.0!, i saw people complainin bout that back in 2007 -.-'
If you are using XSLT 2.0 (or more specifically, XPath 2.0), then you should be able to use the replace function, using a regular expression to capture the substring before the last "/":
http://www.w3.org/TR/xpath-functions/#func-replace
Unfortunately, "replace" did not exist in XSLT 1.0, so it depends on what XSLT processor you are using as to whether this will work for you.
This stylesheet:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="url">
<xsl:variable name="vReverseUrl">
<xsl:call-template name="reverse"/>
</xsl:variable>
<xsl:call-template name="reverse">
<xsl:with-param name="pString"
select="substring-after($vReverseUrl,'/')"/>
</xsl:call-template>
</xsl:template>
<xsl:template name="reverse">
<xsl:param name="pString" select="."/>
<xsl:if test="$pString">
<xsl:call-template name="reverse">
<xsl:with-param name="pString" select="substring($pString,2)"/>
</xsl:call-template>
<xsl:value-of select="substring($pString,1,1)"/>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
With this input:
<url>http://www.site.com/subsite/doclibrary1/FileName.doc</url>
Output:
http://www.site.com/subsite/doclibrary1
One line XPath 2.0:
string-join(tokenize(url,'/')[position()!=last()],'/')
See my answer to this question and use the same technique (#Alejandro's answer essentially copies this).

How to remove particular characters from a string using XSLT?

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>
