RE: Is it possible to dynamically select portions of an XML page?

[Mike Dierken <mike@xxxxxxxxxxxxxxx>]

When I've run into this issue, I use dynamic entity references.
I have a simple servlet which takes URL query terms and uses their
name/value pairs to 'adjust' the entity declarations in an internal DTD of
the .XSL file.
It's like passing parameters to the stylesheet.

<!DOCTYPE sample [
 <!ENTITY title "book1" >
]>
<xsl:for-each select="BOOKSTORE/BOOK">
	<xsl:if test=".TITLE='&title;'">
	<!-- show the book details-->
	</xsl:if>
	<!-- else don;t -->
</xsl:for-each>

Here is an article explaining it in a little more detail and with sample
Java code.

Hi,

I have a large XML page, and I want to show only a small part of it via my
XSL sheet.

I put in something like:

	<xsl:for-each select="BOOKSTORE/BOOK">

		<xsl:if test=".TITLE='book1'">
		<!-- show the book details-->

		</xsl:if>

		<!-- else don;t -->
	</xsl:for-each>

and it works fine. Now for the slightly tricky bit. I want the "if"
statement to be dynamic. I can pass the ASP page I am displaying the XML in
a querystring. So is there a nice way to pass the querystring to the
stylesheet and have it act on it?

something like (but not, since you can;t use % symbols)

<xsl:if test=".TITLE='<%=Request.QueryString("title")%>'">


Or is there another workaround?

Hope this is clear.

Rgs,
