Re: String replacement in included content

<xsl:variable name="contents" select="document(string($componentFilename))//body/form/*" />
<xsl:apply-templates select="exslt:node-set($contents)" />

you don't need a node-set extension here, (some node set extension
implemenattions would probably generate an error as they expect a result
tree fragment as argument but $contents is a node set.

so you can just use
                       <xsl:apply-templates select="$contents" />

which means you don't need the variable either, and canuse

                       <xsl:applt-templates
select="document(string($componentFilename))//body/form/*" />

As a first attempt, ignoring the stuff about replacing %CT% when there is
no tag defined, I tried modifying this template to use the str:replace
template available at www.exslt.org, but that has not worked out so well.

You need to apply the string replacement (separately) to each attribute
and text node.

You don't show the templates that are invoked by the above
apply-templates call but they need the replacement call adding, perhaps
in new temlates such as
<xsl:template match="text()">
<xsl:value-of select="str:replace(....
</xsl:template>

I would rather do this with XSLT because I can then display
a document with a browser

Browser XSLT implementations don't support exslt though do they?
(mozilla doesn't support any extensions at all)

Thanks for your help.
