Re: [CEDET-devel] xslt templates support in ECB

[Mansour Al A. <man...@gm...>]

Hello Eric,
Thank you for helping in this.
There's a mode that I didn't install and not familiar with for XSLT
http://www.emacswiki.org/emacs/xsl-mode.el
 I am not at that point, as I am stuck trying to understand the function:
==============================================
semantic-tag-get-attribute is a compiled Lisp function in
`semantic-tag.el'.

(semantic-tag-get-attribute TAG ATTRIBUTE)

>From TAG, return the value of ATTRIBUTE.
ATTRIBUTE is a symbol whose specification value to get.
Return the value found, or nil if ATTRIBUTE is not one of the
attributes of TAG.
==============================================

Things I need, is the structure for TAG, and how it's composed.

I can see a function called:
semantic-html-new-section-tag
and it's called from:
 semantic-html-recursive-combobulate-list

But still don't fully understand them. Do I need to modify the
*-html-* part in all these functions and replace it with "*-xsl-*".
Like semantic-html-new-section-tag change to
semantic-xsl-new-section-tag  ??
