[xsl] XSLT for mergig XML fragments into the base XML

[Zeev Atlas <zatlas1@xxxxxxxxx>]

I have a main XML file like this:

<myxmlroot>
<myxmlproject>
<myxmlincludetype1 filename="SOMEFILE1"/>
<myxmlincludetype2 filename="SOMEFILE2" attributes.../>
<myxmlbranchhead branchname="STEP1" attributes...>
<myxmlleafnode leafnodename="LFNM1" attributes.../>
etc.
<myxmlbranchhead/>
<myxmlproject/>
<myxmlroot/>



The fragments look like (SOMEFILE1)



<myxmlroot>
<myxmlincludetype2 filename="SOMEFILE3" attributes.../>
<myxmlbranchhead branchname="STEP3" attributes...>
<myxmlleafnode leafnodename="LFNM3" attributes.../>
etc.
<myxmlbranchhead/>
<myxmlroot/>


Only myxmlincludetype2 is available in the fragment. Both 
myxmlincludetype1 and myxmlincludetype2 are optional. When present they 
mean that the filename, which contain the fragment should be read, 
stripped from the myxmlroot tags and embeded in the output XML. The 
process is recursive. So the output should look like this:



<myxmlroot>
<myxmlproject>
<myxmlincludetype1 filename="SOMEFILE1"/>
here would be the fragment from SOMEFILE1
<myxmlincludetype2 filename="SOMEFILE3" attributes.../>
here would be the fragment from SOMEFILE3
<myxmlbranchhead branchname="STEP3" attributes...>
<myxmlleafnode leafnodename="LFNM3" attributes.../>
etc.
<myxmlbranchhead/>

<myxmlincludetype2 filename="SOMEFILE2" attributes.../>
here would be the fragment from SOMEFIL2
<myxmlbranchhead branchname="STEP1" attributes...>
<myxmlleafnode leafnodename="LFNM1" attributes.../>
etc.
<myxmlbranchhead/>
<myxmlproject/>
<myxmlroot/>



Could anybody please guide me where to look or even give me a sample 
XSLT file that handle similar case, it is the first time I deal with XML 
and XSLT

Thanks
