> How can I do this in XSLT?
Not by trying to update a variable, that's not the way XSLT works.
Do it like this:
<xsl:variable name="commentVar">
<xsl:for-each select="Header">
<xsl:value-of select="Comment"/>
</xsl:for-each>
</xsl:variable>
<Comments>
<xsl:value-of select="$commentVar"/>
</Comments>
Of course, you might not need a variable at all, you can just do the
xsl:for-each inside the <Comments> element.
In XPath 2.0 / Saxon 7.0, you can just do:
<Comments>
<xsl:value-of select="Header/Comment" separator=""/>
</Comments>
