I've been using the + following stylesheet in a real-world application to merge two XML documents + without duplication. The ID attributes are used to prevent duplicates. The + "otherfile" parameter is passed in to reference the other XML document to be + merged with the primary XML document being transformed. + + The for-each loop that traverses the nodes in the "otherfile" is working, but + for every entry the @ID is null. Doing a value-of select="." shows the expected + content of each entry. + + Here is the section of the stylesheet where the problem ocurs. + + <xsl:for-each select="document(string($otherfile))/calendar/entry"> + <<<<PRINTING OUT VALUE OF ENTRY NODES HERE IS OK >>>> + <xsl:if test="not(contains(string($tbcids),@ID))" > + <<<<NEVER GET HERE -- @ID IS ALWAYS NULL MATCHING THE $tbcids string >>>> + <xsl:copy-of select="."/> + <xsl:text>
</xsl:text> + </xsl:if> + </xsl:for-each> + + I've provided the XML from two docs. The transformation should + result in the simple merging of all the entry elements from + both docs, since their ID attributes don't overlap. + + XSL (merge.xsl) + =============== + <xsl:stylesheet version="1.0" + xmlns:xsl="http://www.w3.org/1999/XSL/Transform";> + <xsl:param name="otherfile" select="'none'"/> + + <!-- otherfile is the calendar.xml file --> + <!-- Merge tbc (to-be-confirmed) and calendar entries, removing duplicates from + calendar --> + <!-- also used for single entry string buffer as the XML source when editting + the entry --> + + <!-- Bug in xsltc, xsl:text works as long as no xsl:output element --> + <!--<xsl:output method="xml" omit-xml-declaration="yes" />--> + + <xsl:template match="calendar"> + <calendar><xsl:text>
