Assign a length restriction attribute from one element to another using Xpath

Question

Hi, First of all, thanks to Paul for the illuminating article on length restriction. https://multifarious.filkin.com/2014/05/02/xml-length-restrictions/ In my case though, the attribute I want to use as length restriction rule for my translatable segments is in another node like this: Text

10 PX

I know I can select the x-length attribute using this Xpath expression: //context[@context-type='x-length'] But I can't figure out what to put in the "edit" and "advanced" tabs of the //target parser rule settings of my custom file type, so that the translatable segment picks up on the length restriction value and shows it the document structure column. I would very much like to be able to use the QA Checker length restriction option to check for this. Any help would be greatly appreciated. *Edit: typo

Hi S. Carter ,

I don't think this is possible (with XPATH alone) because you'd need to pick up a variable value out of the text " 10 PX " inside the context element. It's unfortunate the developer didn't write the XML in a more usable way, even just like this would have been better (untested, but I think it would be possible):

<context context-type="x-length">10</context>

Perhaps you can make use of a stylesheet instead and show the value in the preview? Doesn't help wrt the automatic QA length check but its similar to having it as a visual check in the DSI column.
