Simon,
Although most browsers will accept a single <option> tag
XSLT can only output 'wellformed' tags
Try thinking of building an output tree (the HTML) from the inputtree
(the XML) instead of outputting text
Perhaps this will work
...
<xsl:if test="position()=1">
<OPTION VALUE="{name()}"><xsl:value-of select="name()"
/></OPTION>
</xsl:if>

Subject: [xsl] Building a HTML select list from XML nodes
Hi
Another New recruit... :-) I would be grateful for any help on
this as it is my first real XSL project.
I am trying to build a list of all the unique nodenames available in
an xml file and present it as a selectable drop down list in an HTML
page.
I am using IE 5.5 and MSXML on Windows 95. At the moment I have all
the files saved on my windows desktop so everything is local.
My problem is that when I open the HTML page, the surrounding text and
select box apprear, but there is nothing to select in the
box. If I change the output method to text I can see that my newline
has no effect at all. The listbox OPTION statements appear as one
long line. If I put a <BR /> tag in the loop and comment out the FORM
and SELECT tags then it will print the text in the same way as if I had
typed the HTML by hand - if I paste it into a file and test it in the
browser as a fixed page it all works perfectly.
I searched on the Web and found that preserveWhiteSpace has some
effect on spacing but, I'm not so sure that this is the solution. I just
can't
get it to work. I'm sure that I am missing something simple.
I have included a sample XML plus my XSL and HTML page. The XSL,
HTML/JavaScript have been patched together from different sources
(web/books).
Many thanks
Simon.
