Hi. I am trying to make a recursive template so I can do a series of
find/changes on text nodes. I may have a lot of them, so I wanted to avoid
nested replace function calls. I am using a parameter for my find/change
pairs. In the recursive call, I am trying to use the current parameter with
[position()>1] to "pop" the first one off the list. It is not working and I
think it is a problem with this line:
<xsl:with-param name="regex" select="$regex/regex[position()>1]"/>
but I am not sure the correct way to do this.
Here is my input file:
<?xml version='1.0' encoding='UTF-8'?>
<test><p class="Note">abcdefghij.</p></test>
Here is my stylesheet:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="xs"
version="2.0">
<xsl:output indent="yes"/>
<xsl:param name="regexes">
<regex><find>a</find><change>x</change></regex>
<regex><find>b</find><change>y</change></regex>
<regex><find>c</find><change>z</change></regex>
</xsl:param>
<xsl:template match="/">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="p">
<p><xsl:apply-templates/></p>
</xsl:template>
<xsl:template match="text()[string-length(.)>0]">
<xsl:message select="."></xsl:message>
<xsl:call-template name="applyRegexes">
<xsl:with-param name="nodeText" select="."/>
<xsl:with-param name="regex" select="$regexes"/>
</xsl:call-template>
</xsl:template>
<xsl:template name="applyRegexes">
<xsl:param name="nodeText"/>
<xsl:param name="regex"/>
<xsl:message select="$regex"></xsl:message>
<xsl:message select="$regex/regex[1]"/>
<xsl:message select="$regex/regex[position()>1]"/>
<xsl:choose>
<xsl:when test="count($regex/regex)">
<xsl:variable name="temp">
<xsl:value-of
select="replace($nodeText,$regex/regex[1]/find,$regex/regex[1]/change)"/>
</xsl:variable>
<xsl:call-template name="applyRegexes">
<xsl:with-param name="nodeText" select="$temp"/>
<xsl:with-param name="regex"
select="$regex/regex[position()>1]"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$nodeText"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
Thanks in advance for any help or pointers.
