My guess would be that these paths aren't working because the msg,
req, dta, SHOW_PO_007, DATAAREA, SHOW_PO and/or POHEADER elements are
in a namespace in your XML document. Without seeing your source
document I can't tell, but this seems to be the most likely
explanation.

If you have a default namespace declaration in your source document
then you should have a similar namespace declaration in your XSLT
stylesheet, but one that associates that namespace with a prefix. You
should then use that prefix in your files. For example if you declare
it with the prefix 'oagis' then you should use:

<xsl:template match="oagis:POHEADER/of:USERAREA/of:TRANSMETHD"
              mode="copy">
  ...
</xsl:template>

This template will only match of:TRANSMETHD elements that are children
of of:USREAREA elements, so I don't understand why you say that it
might match POLINE elements as well.

Having '//' at the start of a pattern is always superfluous. The
match pattern:

  of:USERAREA/of:TRANSMETHD

does just the same thing as the match pattern:

  //of:USERAREA/of:TRANSMETHD

it's just in the latter pattern, as well as testing whether the
of:TRANSMETHD element has a of:USERAREA parent, you're testing whether
that of:USERAREA element is a descendant of the root node. Every
element in the document is a descendant of the root node, so there's
little point testing that.

Cheers,

Jeni
