Re: Conditional extraction of data

I believe this should solve your problem, if I've understood it.

<xsl:template match="tag1 | tag3 | tag4">
<xsl:copy><xsl:copy-of select="@*"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="tag2">
<i><xsl:apply-templates/></i>
</xsl:template>

always assuming that you have not defined a template for text()
and assuming that you don't have any requirements for doing stuff that can't be
done, like copying cdata as is.
also assuming that there is not requirement to keep whitespace as is in the
original content.
