returning to the main input document from XSLT

[Andy Fish]

Say I am in an XSLT template with the context node set to a node from an
alternative document (i.e. read by the document() function). Is there any
way to select nodes from the original document again?

e.g.

<xsl:template match="foo">
<xsl:apply-templates select="document(doc.xml)" mode="otherdoc" />
</xsl:template>

<xsl:template match="bar" mode="otherdoc">
now my context node is a node in doc.xml. how can I select a node from the
main document?
</xsl:template>

You could pass a parameter with the main root node (or any other nodes
you want to pass) e.g.
<xsl:apply-templates select="document(doc.xml)" mode="otherdoc">
<xsl:with-param name="primary-root" select="/" />
</xsl:apply-templates>

<xsl:template match="bar" mode="otherdoc">

<xsl:template match="/" mode="otherdoc">
<xsl:param name="primary-root" />
<!-- access $primary-root or descendants e.g.
$primary-root/* here
-->
</xsl:template>

You could pass a parameter with the main root node (or any other nodes
you want to pass) e.g.

or (simpler) define
<xsl:variable name="origroot" select="/"/>
as a global variable outside any template then it is available in all
templates without having to be explictly passed from one to the other.

If there are lots of documents and nested calls from one to the other
then of course you do need to explictly pass parameters with the nodes
giving the right context and Martin's more general solution is your
friend in that case.
