Merging Infopath Forms

[Sumit]

Hi All,

How can i merge two infopath forms with different schemas? I would be
greatly obliged if someone could provide me the step by step
instruction to do this. While going through some of the articles on the
net i found it that we have to change the xsl file of the infopath
form. Can somebody provide an insight of how to change an xsl file, so
that the changes are reflected?

Thanks,
Sumit
