Bypassing "whatever" you mean by expandable, this should be a very simple transformation. I recommend that you check out zvon.org's website for a tutorial and reference on XSLT. If you were looking for code from somebody on here, I'd give up on that -- it'll be a long wait.

hi

i know little bit xsl;but i want to display hierarchical tree using xsl;

[Nathaniel Stoddard]

Well, I would recommend learning a little bit more xslt, and then using it.

It would also help if you could define "expandable" for us?

[kesava chaitanya]

expandable means i hierarchical tree view with + ,- signs;

And you want it to show up on a web page, right? Then the first thing you should do is to write the necessary HTML+JavaScript for doing this. Then, you can develop an XSL stylesheet which transforms your XML into the HTML+JavaScript doing the expand/collapse thing.
