How about something like:
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="*[not(*)]">
<xsl:copy-of select="."/>
<xsl:copy-of select="$file2//*[not(*)][count(preceding::*) =
count(current()/preceding::*)]"/>
</xsl:template>
You would apply this transform to file1.xml and reference file2.xml
using the document() function.
You could speed it up by using a key for the lookup into $file2 as the
heavy using of the preceding axis would likely make this very slow.
If there are a different numbers of leaf nodes at the same point in
each file then you would need work on the level above, eg:
<xsl:template match="*[*[not(*)]]">
<xsl:copy>
<xsl:copy-of select="*"/>
<xsl:copy-of select="$file2//*[*[not(*)]][count(preceding::*) =
count(current()/preceding::*)]/*"/>
</xsl:copy>
</xsl:template>
If there is mixed content at the level above (<foo> level) use copy-of
select="node()", but if all your text nodes are contained by leaf
nodes then this should be fine.
