XML XSLT return values for duplicate/repeating elements
Very new to XML so excuse if I don't have my terms right yet.
I've got some XML looks like this:
<port protocol="tcp" portid="21"><state state="open" /><service name="ftp" method="table" conf="3" /></port>
<port protocol="tcp" portid="53"><state state="open" /><service name="domain" method="table" conf="3" /></port>
<port protocol="tcp" portid="80"><state state="open" /><service name="http" method="table" conf="3" /></port>
<port protocol="tcp" portid="135"><state state="open" /><service name="msrpc" method="table" conf="3" /></port>
I'm want to return all values for "service name" and display in a single cell of a table (i.e., ftp, domain, http, msrpc).
All I get with <td><xsl:value-of select="ports/port/service
What am I trying to do (by that I mean, what is the operation called)? And, better yet, how do I do it?

tnapolitano,
I have templates (rules based nature of XSLT) for the different elements
and inside one template I push nodesets to the templates with apply-templates
like that I create a very hierarchical model for processing the XML
the stylesheet starts working with the template match="/"
There I create the html and body tag and in the middle of that I push all the chilnodes to the templates
The element "ports" gets picked up by the template for "ports"
and there I create a table and push the port nodes to the templates
As you see now, I have created a table inside the html/body
the template match="port" will be executed for every port element inside ports
this is how I create a number of rows , one for each port
If you would want only one row, this is what you would do
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/">
<html>
<body>
<xsl:apply-templates/>
</body>
</html>
</xsl:template>
<xsl:template match="ports">
<table border="1">
<tr>
<xsl:apply-templates select="port"/>
</tr>
</table>
</xsl:template>
<xsl:template match="port">
<td><xsl:value-of select="service/@name" /></td>
</xsl:template>
</xsl:stylesheet>
take your time to understand the examples
note that this way of programming XSLT is superior over using for-each loops
cheers

tnapolitano,
from your title I assume that you only want unique values
here would be the XSLT that ignores a duplicate value "ftp" and only shows it want
I do this by being selective on the port-nodes that I push to the port template
(it should not have a value of service/@name that a preceding port element has)
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/">
<html>
<body>
<xsl:apply-templates/>
</body>
</html>
</xsl:template>
<xsl:template match="ports">
<table border="1">
<tr>
<xsl:apply-templates select="port[not(service/@
</tr>
</table>
</xsl:template>
<xsl:template match="port">
<td><xsl:value-of select="service/@name" /></td>
</xsl:template>
</xsl:stylesheet>
I hope this is enough to get you started

Gertone, thanks for all that. Let me try this out and I'll get back to you.

Great answer, gertone. Just what I needed. Both the code to get the job done and explanations of what's going on. Thanks again.

I accept this answer. You can close it out.
This XSLT will make you a table with all the values
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/">
<html>
<body>
<xsl:apply-templates/>
</body>
</html>
</xsl:template>
<xsl:template match="ports">
<table border="1">
<xsl:apply-templates select="port"/>
</table>
</xsl:template>
<xsl:template match="port">
<tr>
<td><xsl:value-of select="service/@name" /></td>
</tr>
</xsl:template>
</xsl:stylesheet>
Cheers!
