XSLT: un modo semplice per unire i file xml

Question

Ho due file xml. Ho bisogno di unirli insieme dove l'elemento "myid" corrisponde tra i due. Si prega di dare un'occhiata a questi file di esempio ...

file1.xml:

<?xml version="1.0" encoding="ISO-8859-1"?> 
<catalog> 
    <data> 
    <title>Title1</title> 
    <description>Description1</description> 
    <myid>1</myid> 
    </data> 

    <data> 
    <title>Title2</title> 
    <description>Description2</description> 
    <myid>2</myid> 
    </data> 
</catalog> 

File2.xml:

<?xml version="1.0" encoding="ISO-8859-1"?> 
<catalog> 
    <data> 
    <author>Author1</author> 
    <date>12/34/5678</date> 
    <myid>1</myid> 
    </data> 

    <data> 
    <author>Author2</author> 
    <date>87/65/4321</date> 
    <myid>2</myid> 
    </data> 
</catalog> 

Il file risultante sarà simile:

<?xml version="1.0" encoding="ISO-8859-1"?> 
<catalog> 
    <data> 
    <title>Title1</title> 
    <description>Description1</description> 
    <myid>1</myid> 
    <author>Author1</author> 
    <date>12/34/5678</date> 
    </data> 

    <data> 
    <title>Title2</title> 
    <description>Description2</description> 
    <myid>2</myid> 
    <author>Author2</author> 
    <date>87/65/4321</date> 
    </data> 
</catalog>

Ho cercato un po 'e ho trovato una domanda abbastanza simile qui: http://forums.tizag.com/showthread.php?p=76699

Ecco cosa mi è venuto in mente, questo sembra essere per lo più funzionante tranne che Firefox non lo riconosce come un file xml anche se ho aggiunto l'output xml :.

file1.xml (linea di nota due, che fa riferimento la nostra trasformazione):

<?xml version="1.0" encoding="ISO-8859-1"?> 
<?xml-stylesheet type="text/xsl" href="merge.xsl"?> 
<catalog> 
    <data> 
    <title>Title1</title> 
    <description>Description1</description> 
    <myid>1</myid> 
    </data> 

    <data> 
    <title>Title2</title> 
    <description>Description2</description> 
    <myid>2</myid> 
    </data> 
</catalog> 

File2.xml:

<?xml version="1.0" encoding="ISO-8859-1"?> 
<catalog> 
    <data> 
    <author>Author1</author> 
    <date>12/34/5678</date> 
    <myid>1</myid> 
    </data> 

    <data> 
    <author>Author2</author> 
    <date>87/65/4321</date> 
    <myid>2</myid> 
    </data> 
</catalog> 

merge.xsl:

<?xml version="1.0" encoding="ISO-8859-1"?> 
<xsl:transform version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
    <xsl:output method="xml" version="1.0" encoding="ISO-8859-1" indent="yes" /> 
    <xsl:variable name="with" select="'File2.xml'" /> 

    <xsl:template match="@*|node()"> 
    <xsl:copy> 
     <xsl:apply-templates select="@*|node()" /> 
    </xsl:copy> 
    </xsl:template> 

    <xsl:template match="scene"> 
    <xsl:copy> 
     <xsl:apply-templates select="@*|node()" /> 
     <xsl:variable name="info" select="document($with)/catalog/data[myid=current()/myid]/." /> 
     <xsl:for-each select="$info/*"> 
     <xsl:if test="name()!='myid'"> 
      <xsl:copy-of select="." /> 
     </xsl:if> 
     </xsl:for-each> 
    </xsl:copy> 
    </xsl:template> 
</xsl:transform> 

XML in uscita durante la visualizzazione File1.xml:

<catalog> 
    <data> 
    <title>Title1</title> 
    <description>Description1</description> 
    <myid>1</myid> 
    <author>Author1</author> 
    <date>12/34/5678</date> 
    </data> 

    <data> 
    <title>Title2</title> 
    <description>Description2</description> 
    <myid>2</myid> 
    <author>Author2</author> 
    <date>87/65/4321</date> 
    </data> 
</catalog>
