Question

I have a javascript file that looks like this:

if (x > 0 && x < 100) {
    $('#thing').append('<foo id="foo' + x + '">' + stuff + '</foo>');
}

And an xsl stylesheet that looks like this:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
    <xsl:template match="foo">
        <div>
            <xsl:copy-of select="@*"/>
            <xsl:value-of select="."/>
        </div>
     </xsl:template>
</xsl:stylesheet>

I want to be able to apply that template and possibly other ones to the xml contained in the javascript file.

In this case, the output should look like this:

if (x > 0 && x < 100) {
    $('#thing').append('<div id="foo' + x + '">' + stuff + '</div>');
}

I will use the following constraints on the javascript file if it makes it easier to parse:

1. I will never use &, <, or > inside or between the XML tags.
2. I will never use nested XML tags.
3. I will only use double quotes (“) in or around the XML tags to set the element attributes.
4. I will always have one or more spaces surrounding each < or > character in the regular javascript parts of the text.

I might be able to make other constraints as necessary.

I am using Saxon, so I can use XSLT 2.0 functions and saxon extensions.

This seems to work (your input text in jsxml.txt):

$ saxon9 -it main jsxml.xsl
if (x > 0 && x < 100) {
    $('#thing').append('<div id="foo' + x + '">' + stuff + '</div>');
}


<xsl:stylesheet version="2.0"
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
        xmlns:dpc="data:,dpc">

<xsl:import href="http://web-xslt.googlecode.com/svn/trunk/htmlparse/htmlparse.xsl"/>

<xsl:output method="text"/>

<xsl:template name="main">
 <xsl:variable name="in" select="unparsed-text('jsxml.txt')"/>
  <xsl:copy-of select="dpc:serialise(dpc:apply-templates(dpc:htmlparse($in,'',false())))"/>
 </xsl:template>


<xsl:function name="dpc:apply-templates">
 <xsl:param name="n"/>
 <xsl:apply-templates select="$n"/>
</xsl:function>

<xsl:function name="dpc:serialise">
 <xsl:param name="n"/>
 <xsl:apply-templates select="$n" mode="verb"/>
</xsl:function>

<xsl:template mode="verb" match="*">
 <xsl:value-of select="concat('&lt;',name())"/>
 <xsl:value-of select="@*/concat(' ',name(),'=&quot;',.,'&quot;')"/>
 <xsl:value-of select="'&gt;'"/>
 <xsl:apply-templates mode="verb"/>
 <xsl:value-of select="concat('&lt;/',name(),'&gt;')"/>
</xsl:template>



<xsl:template match="foo">
 <div>
  <xsl:copy-of select="@*"/>
  <xsl:value-of select="."/>
 </div>
</xsl:template>

</xsl:stylesheet>
