RE: [xsl] merge/join two xml files.

["Michael Kay" <mike@xxxxxxxxxxxx>]

It depends on many details that you haven't supplied, but let's assume 

(1) apart from the handling of X, the rest of the transformation is copying
A.xml unchanged.

(2) the element that might or might not contain an X child is called P, and
this is the only P element in the document, and the X element from B.xml is
to be added as the last child of P.

Then with A as the principal input document do:

<xsl:template match="*">
  <xsl:copy>
  <xsl:copy-of select="@*"/>
  <xsl:apply-templates/>
  </xsl:copy>
</xsl:template>

<xsl:template match="P[not(X)]">
  <xsl:copy>
  <xsl:copy-of select="@*"/>
  <xsl:apply-templates/>
  <xsl:copy-of select="document('B.xml')//X"/>
  </xsl:copy>  
</xsl:template>
