xpath question (bug, specs, ask for help)
Hi All,
Say I have the following two queries:
short_query_1 = "//ja/PressRelease/avs222"
short_query_2 = "//ja/PressRelease/2005report1"
The first one returns a result. (or not depending if nodes are
present ...)
The second throws the followingexception:
: Encountered "return" at line 1, column 40.
Was expecting one of:
<IntegerLiteral> ...
<DecimalLiteral> ...
<DoubleLiteral> ...
The path containing a name within the path starting with an integer
is causing troubles. I can reproduce this reliably.
Did I miss something in the XPath specs that said I should have path
names with the problematic pattern ?
Or is this a bug ? (My side, jackrabbit side, configuration ...)
Thank you in advance for any pointers,
Nicolas,

Sounds great! This way everyone can participate.

This would be a great idea, and I would participate.
Clear informations about jackrabbit implementation of xpath, the limitations and so on would be veeery useful ;)

Having an up to date FAQ would be great. I've been thinking about
dropping the badly outdated FAQ on the official Jackrabbit web site
and just linking to a wiki page where people can more easily add and
update stuff.

Having an up to date FAQ would be great. I've been thinking about
dropping the badly outdated FAQ on the official Jackrabbit web site
and just linking to a wiki page where people can more easily add and

There are a few topics like that which come up frequently on this list. I think
we should at such items to the FAQ. What do the others think? Jukka?

Hi Christoph, and list,
Thank you for your quick reference.
Just as a follow up on this, for other people, a path like:
/ja/2005report1
would really need just the first character of 2005report1 to be
encoded to be properly searched. So that would give us and xpath
query like:
//ja/PressRelease/_x0032_005report1
Note also that the hexa decimal needs to be on four digits.
One last note, encoding the whole name in hexa doesn't work. Each
hexa character would need to be surrounded by the "_x" and "_"
characters.
So in our example, the xpath would be the following:
//ja/PressRelease/_x0032__x0030_05report1
Hope that this can help someone in the future.
As Jan Kuźniak noted last december, it would be really great if this
was transparent.
Thanks again,
Nicolas,
