ITS and XPath

[Michel Farhi-chevillard]

Hi, 

I would like to set my localization note to a specific node if it exists, or another node if the first node doesn't exist.

So, I need to create an XPath expression for  locNotePointer that would do that.

According to what I read at https://stackoverflow.com/questions/27234421/xpath-expression-which-selects-nodea-if-it-exists-but-otherwise-fall-back-to-no, I would need XPath 2.0 for that.

Does ITS 2.0 support XPath 2.0 or only XPath 1.0? The documentation only talks about XPath 1.0, but I was wondering.

To illustrate what I want to do, here is a sample of my XML file:

   </entry>

   <entry key="PluginActionLaunchExecutable" needsReview="no">

      <loc>Launch</loc>

   </entry>

   <entry key="SolverProblemPackageNameAndVersionFormat" needsReview="no">

      <loc>{0} ({1})</loc>

      <comment>0=name, either display name or package name; 1=version, either display version or package version</comment>

   </entry>

For the first entry, since <comment> isn't there, I want to set the loc note to @key.  For the second entry, since <comment> exists, I would like to set it to that comment.

Thanks

ITS 2.0 only supports XPath 1.0 -- this is part of the spec.

The filter's XPath implementation is based on Saxon-HE, which supports XPath all the way up to 3.1, but accesses it through a JAXP wrapper which only supports XPath 1.0.  I have not tried putting XPath 2.0 rules into an ITS configuration -- it would be a good experiment.

Thanks, so far, I am not making this work, so I think I'm going to drop this idea...   Too bad!
I keep getting errors like:

Bad XPath expression in pointer '(../@key,../comment)[1]:
javax.xml.transform.TransformerException: Expected ), but found: ,'.

Hi Michel,

It may not be perfect, but given an all or nothing approach, maybe you can consider using a concatenation of both (e.g. "concat(../@key, '|', ../comment)") using xpath 1, so when there is a comment you will get it on top of getting the @key attribute. Again, not perfect because it is not OR, but at least you add plenty of information to your localization notes.

[Michel Farhi-chevillard]

That's a technique I use to set the <resname> using itsx:idValue and a concatenation, but it's not available for the localization <note> element, for which you have to set the locNotePointer. 
Unless of course you can show me otherwise, maybe I missed something obvious...

Thanks!

Fair point, Michel.

What if you create two rules for notes, the first one pointing to the @key attribute, the second one to the comment node?

See a couple of screenshots using those two rules in that order and using the same xml content structure you shared with a few additional nodes.

Attaching the second screenshot, which was not uploaded to the previous message. Apologies for the additional message.
