-----> I'm now writing a cpp program using libxslt api's over libxml
api's. I have the pointer to the dom tree for "merge.xslt" and another
dom tree for "merge.xml". Using these api's I could apply the xslt on
the xml.

But the content of the merge.xml is, which merge.xslt needs, is the 2
files which needs to be merged.

Instead, I would like to pass the DOM trees for these 2 files for
applying merge.xslt on it.

---> so, otherwise how do I merge several xml files using the xslt
library api's in cpp.
And is there any examples can you send me, which would read the
document URI's and use it for merging xml's.

Thanks for helping this far and trying to understand my problem.
Thanks a lot.
