Re^2: xml::xslt xpath question

I'll add the full xml below but my biggest challenge is in finding the xpath methods that are available in Perl to select a node by its attributute value - when the attribute value includes space.

Simplified XML: `<?xml version="1.0" encoding="utf-8"?> <PLMXML xmlns="http://www.plmxml.org/Schemas/PLMXMLSchema"> <Form subType="Part Revision Master"> <UserData> <UserValue title="cage_code" value="98747"/> </UserData> </Form> </PLMXML>` [download] You keep mentioning spaces, but I don't see why that would be a problem. Did you try fixing the the missing "`[`" I mentioned? If the first snippet doesn't work with the missing "`[` fixed, I suspect a namespace problem. I don't know how XSLT deals with namespaces, so I can't help you there. Outside of XSLT, your XPath would be wrong since it references elements in the null namespace while they are in the `http://www.plmxml.org/Schemas/PLMXMLSchema` namespace.	[reply] [d/l] [select]
Re^4: xml::xslt xpath question by Anonymous Monk on Jul 06, 2009 at 20:15 UTC
It seems to have a problem handling spaces because when I use the following xpath statement `<xsl:value-of select="/PLMXML/Form[@subType='Part Revision + Master']/UserData/UserValue[@title='cage_code']/@value"/>` [download] I get the following error `get-node-from-path: Don't know what to do with path [attribute::subTyp +e='Part Re vision Master']/UserData/UserValue[attribute::title='cage_code']/attri +bute::valu e !!!` [download] But if I use the following xpath statement I don't catch an error. `<xsl:value-of select="/PLMXML/Form[@id='id24']/UserData/Us +erValue[@title='cage_code']/@value"/>` [download]	[reply] [d/l] [select]

And I found the bug: `elsif ( $path =~ s/^\/(child\:\:\|)(\\|[\w\.\:\-]+)\[(\S+?)\]// ) ^^^^` [download] Switching that line to following should do the trick: `elsif ( $path =~ s/^\/(child\:\:\|)(\\|[\w\.\:\-]+)\[(.+?)\]//s )` [download] Reported.	[reply] [d/l] [select]
