cdata in xslt for html

Question

I have an XSLT file generating plain HTML. I need to wrap some elements in CDATA blocks, so intend to use cdata-section-elements. But, if the element I want to have contain CDATA is only one <p> on the page, how do I get it to not put CDATA in all the other <p> elements?

The input data is this:

<item>
  ...
  <g:category>Gifts under &amp;pound;10</g:category>
</item>

My XSL is:

<xsl:element name="a">
  <xsl:attribute name="href">productlist.aspx</xsl:attribute>
  <xsl:copy-of select="text()" />
</xsl:element>

I want this to render something like:

Gifts under £10

But all I get is:

Gifts under £10

Well assuming you have some way of targeting the <p> tag that you want to enclose in CDATA section, you could do something like:

<xsl:output method="xml" version="1.0" encoding="UTF-8" 
    indent="yes" omit-xml-declaration="yes"/>

<xsl:template match="/">
    <xsl:apply-templates/>
</xsl:template>
<xsl:template match="p[@test = 'test']">
    <xsl:copy>
        <xsl:text disable-output-escaping="yes">&lt;![CDATA[</xsl:text>
        <xsl:apply-templates/>
        <xsl:text disable-output-escaping="yes">]]&gt;</xsl:text>
    </xsl:copy>
</xsl:template>

<xsl:template match="@*|node()">
    <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>

In this case all <p> tags with an attribute test = 'test' will have CDATA applied to them, all other tags will just be output as normal.

The code I have is:

<xsl:element name="a">
  <xsl:attribute name="href">
    product.aspx?prod=<xsl:copy-of select="title/text()" />
  </xsl:attribute>
  <xsl:text disable-output-escaping="yes">&lt;![CDATA[</xsl:text>
  <xsl:copy-of select="g:price" /> - <xsl:copy-of select="title/text()" />
  <xsl:text disable-output-escaping="yes">]]&gt;</xsl:text>
</xsl:element>
