Joerg,
Thanks. Very close now...
The only thing causing a problem now is that a Media
element can contain two child elements, Link and/or
Caption. I actually had a Link element outside of a
Media element before, but that *SHOULD* not happen.
Both the Link and Caption elements contain text nodes.
So, something like this:
<p>
<Media type="image" id="1"
file="http://www.mylocal.gov/images/aero.gif"
width="54" height="54" border="" alt="Picture of the
shuttle parachute.">
<Link url="mytestfile.htm" type="external"/>
<Caption align="bottom">Picture of the shuttle
parachute.</Caption>
</Media>
</p>
will pass the test even though it is only an image.
Sorry I left that out. That is the only snag left
preventing your solution from working.
I tried adding to it myself, but I just do not
understand axis conditionals well enough.
<xsl:when
test="descendant::node()[normalize-space()][not(self::Media
or descendant::Link or descendant::Caption)]">
<p><xsl:apply-templates/></p>
</xsl:when>

Hi Nathan,
it should work in your example too, because there is
a text node as
child of the <Link>, so the test is passed.
Only one comment:
<p>
<Link>
</Link>
</p>
The above passes the test because of spaces and line
breaks between <p>
and <Link> or between <Link> and </Link>. To avoid
this you can test on
nodes, which don't consist of only whitespaces
characters. Use
normalize-space() for this
(http://www.w3.org/TR/xpath#function-normalize-space):
<xsl:when
test="descendant::node()[normalize-space()][not(self::Link
or
self::Media)]">
<p><xsl:apply-templates/></p>
</xsl:when>
=> If a descendant node exists, that consists not
only of whitespace
characters, that is not <Link> or <Media>, wrap it
in <p>.

Joerg

Excellent Joerg! The only place this would not
work is
if I have a paragraph element with only a Link
element
in it, such as:
<p><Link href="blah.html">This is a
link</Link></p>
I need those to pass through the test and be
wrapped
in a p tag. Otherwise, it catches everything else
I
need!
Thank you! That gives me great direction...

If there is any descendant node (including
elements,
comments, PIs,
text), which is not element Link or element Media,
create <p> in output
tree.

hi all,
Thanks to everyone who gave me advice on my
previous
post about images and captions. Now, I have
another
tricky lil' xslt problem. If a paragraph element
contains ONLY a media element OR a media element
surrounded by a link element and nothing more
(read,
no other nodes, be they text or not), such as:
<p><img
src="http://www.mylocal.gov/images/nasausa.gif"
height="255" width="432"/></p>
I need to strip the p tags out of resulting
output.
However, if it does contain other nodes, such as:
<p><img
src="http://www.mylocal.gov/images/nasausa.gif"
height="255" width="432"/>This is my news
release.
The
authors will be typing the news release content
in
here! I am not sure what this news release is
even
about, but lets see how it comes out in XML,
shall
we?
As I see it coming out as:</p>
I need to leave it alone.
Here is what I have so far. It only looks to see
if a
media element or a media element wrapped by a
link
element exists, but does not consider if there is
a
text node after a media or link element.
<xsl:template match="p">
<xsl:choose>
<xsl:when test="((descendant::*[1])[self::Link]
and
(descendant::*[2])[self::Media]) or
(descendant::*[1])[self::Media]"><xsl:apply-templates
/></xsl:when>
<xsl:otherwise><p><xsl:apply-templates
/></p></xsl:otherwise>
</xsl:choose>
</xsl:template>
Thoughts? Ideas? Criticisms?
