xpath query failure

the following xpath query is failing with the below stack trace. the 
problem seems to be the space in the item name "morgen calendar-2". the 
space character is obviously allowed in the item name in this position, 
so is this a bug, or am i missing something? thanks!

/jcr:root/morgen/morgen calendar-2//element(*, 
caldav:resource)[@icalendar:uid = 'e505b68c-36c9-11da- cb90-000a95bb2738']

Hi Brian,

sorry for the late reply...

using the class org.apache.jackrabbit.core.util.ISO9075 is probably the
better choice ;)

for what it's worth, i copied 
org.apache.jackrabbit.test.api.EscapeJCRUtil. that class really ought to 
be generally available somehow rather than buried down in the jackrabbit 
test code :)

ah yes, and section 6.6.4.9. thanks for the pointer. i had read down to 
6.6.4.7 but not gone any further :)

i don't see an escaping utility in the jcr api. this seems like code 
that should only have to be written once and be usable by all jcr 
clients. how do other folks handle escaping?

You probably need to escape names.  See section 6.4.3 of JSR-170.

Cheers,
