Re: [xsl] Xpath to node that has a parent with a certain at

Most like the elements are in a namespace, so your match expressions will
not match. 

You can test that by changing "//target[parent::trans-unit[@id="xxx"]]" to
//*:target[parent::*:trans-unit[@id="xxx"]]

If the @id value will be unique within the document then you can do
something like:

//*[@id = 'xxx']/*:target

Also, since you know the structure, you can replace "//", which is very
inefficient, with "/*/*/*" (if I've counted the ancestor levels correctly).

Cheers,

Eliot

Subject:  [xsl] Xpath to node that has a parent with a certain attribute

Hi there, 

I'm struggling to match a node where the parent has a particular id, perhaps
someone can help me.

This is my data:

<xliff>
  <file>
    <header/>
    <body>
    (...)
      <trans-unit id="xxx>
        <source xml:lang="en">foo</source>
        <target xml:lang="sl" state="zzz">bar</target>
      </trans-unit>

I have parsed the file and I am trying expressions

$xliff->xpath('//target[parent::trans-unit[@id="xxx"]]')

and 

$xliff->xpath('//trans-unit[@id="xxx"]/target')

but they both give me the same result:

array(1) {
  [0]=>
  object(SimpleXMLElement)#8 (1) {
    ["@attributes"]=>
    array(1) {
      ["state"]=>
      string(22) "zzz"
    }
  }
}

My expected result is "bar"
What I doing wrong?

I'm doing this in php 5.5.11 with libxml Version 2.9.1.

Thank you so much. 
Cheers, Manuel
