passing arguments to xsl

[Mitch Cunningham]

HI,

i am trying to use the following code to do an xslt transform using
php 4/sablotron with additional optional arguments. can anybody tell
me what i am doing wrong ? i was expecting the output "one two" from
the sample.xsl transform but it seems to treat the variable as a
literal (see below)...

trans.php
--------

<?
echo xslt_process(xslt_create(), 'sample.xml', 'sample.xsl', NULL,
array(), array("pat"=>"out"));
?>

sample.xml
--------

<?xml version="1.0" encoding="UTF-8"?>
<out>
<in>one</in>
<in>two</in>
</out>

sample.xsl
----------

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:param name="pat"/>
<xsl:template match="/">
<xsl:value-of select="$pat"/>
</xsl:template>
</xsl:stylesheet>

OUTPUT

out

alternative.xsl
----------

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:param name="pat"/>
<xsl:template match="/">
<xsl:value-of select="out"/>
</xsl:template>
</xsl:stylesheet>

OUTPUT (substituting alternative.xsl for sample.xslin trans.php)

one two

That behaviour is correct. The statement <xsl:value-of select="$pat"/> will
select the contents of variable/parameter $pat and will treat it as a
string.

If you want to turn a string into a node set then you need the following:
<xsl:value-of select="//*[name()=$pat]"/>
