document() causing variables to be hidden?

["Robert A. Lentz" <ra...@erols.com>]

Greetings,

Still quite new at this, so forgive me if I am misunderstanding...

I guess I understand why a node tree imported via document() would not be 
able to see the tree into which it was imported, though I do not really 
understand why.

But, I find it very odd that variables/parameters seem to get hidden, by 
the document() function.

For an example, please see the attached files:

style_bug.xml - style sheet
bug_test.xml - source document
navigation-bug.xml - included document

(using version j1.2_D2, and sun's Java 1.3)

thank you,
-Robert

Hi!

When I try to access the mailinglist archive at

http://archive.covalent.net/xml/xalan-dev/2000/09/

I get an "Internal Server Error". Is the archive
down?

Thank you!

Robert --

I'm not sure what your first statement means -- maybe you could give an
example to illustrate.  Also, I'm not sure what you mean about
variables/parameters getting "hidden" by the document function.

However, maybe this will help.

When your xsl:apply-templates select="document($nav)/toc" mode="site"
gets executed, the XSLT processor will look for a template matching the
<toc> element.  You haven't supplied such a template so a built-in
template gets invoked.  The built-in template doesn't have an xsl:param
for your area parameter so that parameter is not used by the built-in
template.

The built-in template for an element simply does an xsl:apply-templates
on the child nodes of that element.  So, in your case, it will invoke
the children of the <toc> element.  There is one child, <nav-area>, so
the apply-templates process will look for a template matching nav-area
with mode="site".  You have such a template and you have an xsl:param in
that template.  However, since you are invoked by the built-in template,
no parameters will be passed to the nav-area template.

If you want to pass the parameter, change your XPath select expression
to document($nav)/toc/nav-area.

HTH,
Gary
