Pointers or by-references to nodes in a temporary tree?

I am using Saxon 9.

I find a table of interest by a cross reference and display the title:

Code:

<xsl:value-of select="$repoSubTree//pmtable/pmtitle[@Id eq $myIDRef]"/>

But, I need to do some work based on other parts of this table I just found

I tried:

Code:

<xsl:variable name="myPMTable">
   <xsl:sequence select="$repoSubTree//pmtable[./pmtitle/@Id eq $myIDRef]"></xsl:sequence>
</xsl:variable>

To put the interesting table in a variable so I can do xpath statements to pull information from the table.
For example to get the title, I tried

Code:

<xsl:value-of select="$myPMTable/pmtitle"></xsl:value-of>

But I don't get anything. I also tried copy-of instead of sequence, nothing...

But this really doesn't seem like the right approach anyway. I don't need a another copy of my table, I've already got it in my $repoSubTree temporary tree. I just need a reference or pointer to it stored in a variable that I can use in subsequent xpath statements to find data stored in the table.

Is this sort of thing possible in XSLT?

Thanks,

In XSLT 2.0 the following should work fine:

Code:

<xsl:variable name="myPMTable" select="$repoSubTree//pmtable[pmtitle/@Id eq $myIDRef]"/>

Well, I do feel the idiot now.. I knew I had to be over thinking this.

I did get it to work by adding as="node()" to the line that creates the variable. Apparently I have more reading about as='node()' to do.

But, your answer worked as well.. and I don't have to read about as='node()' just yet.

Thanks!
