Hi team,
I'd like to add the use of leniency to JXPath expressions in JXTemplateGenerator: currently, if a path does not exist, a nice exception is thrown. This may be good in some circumstances (avoids endless hair pulling sessions to finally discover a small typo), but is also required in some situations where the template writer _knows_ that a path may not exist.
Here's what I want to do:
- add a global "lenient-xpath" sitemap parameter to the generator. This allows to set a global leniency mode (default is false, meaning exceptions are raised)
- set leniency always to true on test instructions (<jx:if> and <jx:when>)
- add an optional "lenient" attribute to the <jx:out> and <jx:forEach> statements (would default to the sitemap parameter value above).
What do you think?
+1
JXTemplate (which I like and use) always seems very touchy :) Maybe it could log the times when it had to be lenient.
