Merging two xml data and using the output in same XSLT

Question

I have a got two XML variables and below are sample data in it:

$Variable1:

<Group>
    <A>Test</A>
    <B>Test1</B>
    .....
    .....
    .....
</Group>

$Variable2:

<Data>
    <ABC>Test</ABC>
    <XYZ>Test1</XYZ>
    .....
    .....
    .....
</Data>

Now I want to merge these two variable in XSLT and use the output in same XSLT, so output will be something like below after merge :

<Group>
    <A>Test</A>
    <B>Test1</B>
    .....
    .....
    .....

    <ABC>Test</ABC>
    <XYZ>Test1</XYZ>
    .....
    .....
    .....
</Group>

Above output will be passed in same XSLT for further processing.

Below is the xslt sample, I have tried:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes"/>
  <xsl:param name="var1" select="document($Variable1)" />
  <xsl:param name="var2" select="document($Variable2)" />

  //Here I want to merge above to inputs and later will be used in XSLT below

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

  <xsl:template match="Group">
     -------
     -------
     -------
     -------
  </xsl:template>
</xsl:stylesheet>

Where do your variables `Variable1` and `Variable2` come from? They should be defined inside the style sheet. — Marcus Rickert, Oct 28 '14 at 17:46
"*It is coming from C# code*" That's not possible. Variables/parameters must be defined in stylesheet itself. You can only pass a **value** to a pre-defined parameter. — michael.hor257k, Oct 29 '14 at 05:36

If you take the following stylesheet:

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>

<xsl:param name="file1"/>
<xsl:param name="file2"/>

<xsl:template match="/">
    <xsl:apply-templates select="document($file1)/*"/>
</xsl:template>

<xsl:template match="/*">
    <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
        <xsl:apply-templates select="document($file2)/*/*"/>
    </xsl:copy>
</xsl:template>

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

</xsl:stylesheet>

and pass it the paths to your two files (as strings), will return the following result:

<?xml version="1.0" encoding="UTF-8"?>
<Group>
   <A>Test</A>
   <B>Test1</B>
   <ABC>Test</ABC>
   <XYZ>Test1</XYZ>
</Group>

Of course, you would also need a third (dummy) XML file on which to run the transformation. A smarter implementation would use the first input file as the source XML, and only pass the second file's path as the parameter.

Sorry for delay response.. ...in my case file1 and file2 are XML string which are generated in runtime...they are not a file which we can use for ..any suggestions — Manoj Singh, Nov 20 '14 at 07:38
@ManojSingh There is no such thing as an "XML string". A string is a string - and there's not much you can do with a string using XSLT.

Yes I know there is no such thing like XML String, I was just telling that file1 and file2 will having string values in it, which will be generated on runtime. — Manoj Singh, Nov 20 '14 at 09:51
