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>

I am brand new to XSLT and trying to transform an incoming file to then be processed by another program. The goal is to try and add blank lines to an existing XML file to mimic the page length for the other program to process correctly. I need to count the <line> elements between each <page> element and if that total is less than 75, add the remaining lines as blank. What is the best way to recursively add a blank line in XSLT? So far my incoming XML looks like this:
<page>
<line>Some text</line>
<line>Some text</line>
<line>Some text</line>
etc...
</page>
I have been looking at examples that use nodes to group things together like this (setting the group size variable):
<xsl:call-template name="file">
<xsl:with-param name="nodes" select=".|following-sibling::*[not(position() > $pGroupSize - 1)]"/>
</xsl:call-template>
I have also been finding results that talk about segmented recursion like the example below:
<xsl:template name="priceSumSegmented">
<xsl:param name="productList"/>
<xsl:param name="segmentLength" select="5"/>
<xsl:choose>
<xsl:when test="count($productList) > 0">
<xsl:variable name="recursive_result1">
<xsl:call-template name="priceSum">
<xsl:with-param name="productList"
select="$productList[position() <= $segmentLength]"/>
</xsl:call-template>
</xsl:variable>
<xsl:variable name="recursive_result2">
<xsl:call-template name="priceSumSegmented">
<xsl:with-param name="productList"
select="$productList[position() > $segmentLength]"/>
</xsl:call-template>
</xsl:variable>
<xsl:value-of select="$recursive_result1 + $recursive_result2"/>
</xsl:when>
<xsl:otherwise><xsl:value-of select="0"/></xsl:otherwise>
</xsl:choose>
</xsl:template>
Any help on the best way to approach this would be appreciated.
I think you're making this more complicated than it needs to be. Even in XSLT 1.0, you could do simply:
<xsl:template match="page">
<xsl:copy>
<xsl:copy-of select="line"/>
<xsl:call-template name="generate-lines">
<xsl:with-param name="n" select="75 - count(line)"/>
</xsl:call-template>
</xsl:copy>
</xsl:template>
<xsl:template name="generate-lines">
<xsl:param name="n"/>
<xsl:if test="$n > 0">
<line/>
<!-- recursive call -->
<xsl:call-template name="generate-lines">
<xsl:with-param name="n" select="$n - 1"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
(This question is a less simplified version of my problem. The more simplified version which was already answered can be found here. I'm posting this more complicated question due to a comment by michael.hor257k who suggested that there may be an alternative approach that could solve it - possibly using select in a loop, or possibly a completely different approach.)
I'd like to process an XML file, over whose format I have no control, to generate C++ code. I need to process functions defined in XML in several different ways to produce different parts of the code. As part of this I need to select a subset of function parameters that match a complicated criteria and pass this selection to several named templates; the named templates need to be able to access the original document.
This example creates a complex selection of C++ function parameters that do not have constant values (ie the same min and max), where the min and max may be decimal or hexadecimal, using the "GenerateNonFixedParameters" template. The parameters refer to enumerations which are located elsewhere in the document, and these definitions are referenced by the named template call "ListParameterValues".
There are two problems.
The creation of the variable "nonFixedParameters" does not use select. I cannot work out how to use select for such a complicated case (XSL 1.0), but maybe there is a way.
A copy of the nodes does not suffice, as the "ListParameterValues" template as it currently stands needs to operate on an original set of nodes from the document.

I think your stylesheet can be made to work with XSLT 1.0 if you use an extension function like exsl:node-set to convert your result tree fragment into a node-set and if you store the root node of the primary input tree into a global variable or parameter as then you will be able to compare nodes in your primary input document to nodes of the newly constructed, temporary tree.
Based on these suggestions the code would look like
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" xmlns:exsl="http://exslt.org/common">

Let me show a different approach that actually selects and processes the original nodes, in their original context - as was discussed in the previous thread. Consider:
XSLT 1.0

The problem with this approach is that it works exactly as advertised; the nodes selected at the end of the selecting processes are the original, unmodified parameters. As a result, they still carry the mixture of decimal and hexadecimal values, and you must convert these again when processing the selected set.
So it might well be more worthwhile to pre-process the parameters by normalizing the values to a common base, then use the result (converted to a node-set) for the rest of the processing. I wouldn't spend so much effort at selecting those that meet the criteria - because once the values are consistent, the selection becomes trivial. If you like, I will post a demo showing that.
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, '*', ''))))" />
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:param name="path" />
<xsl:choose>
<xsl:when test="contains($path,'/')">
<xsl:value-of select="substring-before($path,'/')" />
<xsl:text>/</xsl:text>

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($pString,1,1)"/>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
With this input:
<url>http://www.site.com/subsite/doclibrary1/FileName.doc</url>
Output:
http://www.site.com/subsite/doclibrary1
One line XPath 2.0:
string-join(tokenize(url,'/')[position()!=last()],'/')
See my answer to this question and use the same technique (#Alejandro's answer essentially copies this).
I'm banging my head against the wall trying to figure out why this won't work:
<xsl:call-template name="test-template">
<xsl:with-param name="item" select="WTF" />
</xsl:call-template>
<xsl:template name="test-template">
<xsl:param name="item" />
-~<xsl:value-of select="$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.
