Merge XML

Question

I have 2 Strings representing xml:
(The first String)
<bookshelf>
<book><title>1st Book</title>
<book><title>2nd Book</title>
<book><title>3rd Book</title>
<bookshelf>
(The second String)
<bookshelf>
<book><title>4th Book</title>
<book><title>5th Book</title>
<book><title>6th Book</title>
<bookshelf>
I would like to have the following String:
<bookshelf>
<book><title>1st Book</title>
<book><title>2nd Book</title>
<book><title>3rd Book</title>
<book><title>4th Book</title>
<book><title>5th Book</title>
<book><title>6th Book</title>
<bookshelf>
I read some example of merging file using xslt. But that involves using document() function. Since xml here is in memory I am not sure how to merge 2 xml documents.

Answer 1

But, how do I do that in xslt. xslt is just a template. I think I am missing a point here. I was referring to below example, only problem is that I don't have a file "file2.xml". My xml is in memory. I want to be able to use String that's in memory.
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" indent="yes" />
<xsl:variable name="file2" select="document('file2.xml')" />
<xsl:template match="/bookshelf">
<bookshelf>
<xsl:copy-of select="*" />
<xsl:copy-of select="$file2/bookshelf/*" />
</bookshelf>
</xsl:template>
</xsl:stylesheet>
