[thelist] DOMDocument - was XPATH woes

[Chris Hayes]

Thanks for that.  My head's in a mess.

My problem is with DOMDocument and XPATH.  I should have been more specific.
I'm still on an ASP job I posted about a while back.  I'm really not the
person for the job, but, I am the person on it :(

I have the DOMDocument with the XML loaded
...
<bobtypes>
    <bob id="4"></bob>
    <bob id="7"></bob>
    <bob id="10"></bob>
</bobtypes>
...

to return "4,7,10"

The id values can be any integer within a certain range.  I can happily
retrieve other XML values

Set myVar=xmlDOMDOC.documentelement.selectSingleNode("elroot/abc/xyz")

But I'm having problems with the random id's.  I get an error if I try to
retrieve a bob id that doesn't exist.  I was hoping there was a magic
solution.  I'd need to know more to even make a useful google query.

Any ideas oh wise ones?

Don't think you can do this with a single statement. However, this should do
it...

<xsl:for-each select="/bobtypes/bob">
<xsl:value-of select="@id"/>
</xsl:for-each>

Also here is a decent quick reference for XPATH (among others) at this site,
downloadable in PDF format: http://www.deepx.com/resources/quickref/

Hi

Looking for plain English help for this issue.  I want to return a list of
all the bob id's in the xml below.

<bobtypes>
    <bob id="1"></bob>
    <bob id="2"></bob>
    <bob id="3"></bob>
</bobtypes>

to return "1,2,3"

Is there any XPATH to do this?  Do you have any really good XPATH links to
teach a novice.
