[wtp-incubator-dev] XPath Content Assistance

[David Carver <d_a_carver@xxxxxxxxx>]

Doug and Jesper:

I've reworked a lot of the backend code for the 
XSLContentAssistProcessor.  In particular, the XPath content assistance 
should address issues that Doug raised in bug 224938.   This refactoring 
now parses and tokenizes the XPath expression in the select statements, 
and based on the cursor position will try and determine the correct 
content assistance.   It seems to handle single line XPath expressions 
well.   I will open a separate bug to handle any issues in regards to 
multiline XPath Expressions.

Jesper, you should be able to leverage the XPath Templates as well as 
the new XPathCoreXPathParser class, to get bug 217822 implemented, with 
a line content processor and assistor.

There are several unit tests that show how the XPathCoreXpathParser is 
to be used.   The main parsing is handled by the JXPath Parser from the 
apache commons project, as it was the only one that actually exposed the 
Tokens so that column and line number information could be obtained.

Anyways, if you can do some testing on this, I'd appreciate it.  I know 
there are a few little areas that still need some tweaking but I'm going 
to close the main bug so that we can have separate bugs for the other 
issues that remain.
