Hi,
is it possible to get the result tree and work on it?
I am able to do the transformation on my own via executeChildTemplates.
But I have not found a way to process the result.
<xalan:component prefix="my" elements="countwords">
<xalan:script lang="javascript">
function countwords(context, elem){
transf = context.getTransformer();
transf.executeChildTemplates(elem,true);
return "";
}
</xalan:script>
</xalan:component>
<xsl:template match="/">
<my:countwords>
<text>
some words
<xsl:value-of select="."/>
</text>
</my:countwords>
</xsl:template>
Instead of doing this, I would create an extension function to count
words, then do the following:
<xsl:template match="/">
<xsl:variable name="text">
some words
<xsl:value-of select="."/>
</xsl:variable>
<text count="{ext:count-words($text)}">
<xsl:value-of select="$text"/>
</text>
</xsl:template?
If the whitespace within the "text" element is not interesting, you
could create a string variable, instead of a result tree fragment variable:
<xsl:variable name="text" select="concat('some words ', .)" />
which is more efficient.
Note that it's also possible to write a recursive template to count
words, if you don't want to write an extension function.
