Thank you, like I said at the end of my email I already used the ISO9075
class, so it is nice to receive verification I'm on the right track
here;
however, when I used it to encode '/1/2' my program returns me 0 results
while it should have returned 1 (which is what happens when I run the
query without '/1/2' in front).
String pattern="/1/2";
String patternNew=ISO9075.encode(pattern);
System.out.println(patternNew);
Query q =
qm.createQuery(patternNew+"//element(*,nt:resource)[jcr:contains(.,'aaaa
a')]", Query.XPATH);
QueryResult result = q.execute();
NodeIterator it = result.getNodes();
System.out.println("IT:"+it.getSize());
while (it.hasNext()) {
Node n = it.nextNode();
System.out.println("name:" + n.getName());
System.out.println("path:" + n.getPath());
}
>_x002f_1_x002f_2
>IT:0
while in reality I should be getting
> IT:1
> name:100
> path:/1/2/99/100
which is what I get when I use just
"//element(*,nt:resource)[jcr:contains(.,'aaaaa')]" without "/1/2" in
front.
The jcr spec follows the same syntax in 6.6.3.4 when specifying
descendants so what could be wrong? I still get 0 results even if I put
/jcr:root/1/2 in front. Thank you.
Regards
Giota

Subject: Re: xpath failure
you need to encode the path steps because '1' and '2' is not a valid xml
name. xml names must not start with a digit.
you may use the utility org.apache.jackrabbit.util.ISO9075 to encode the
path steps. The class is included in the jackrabbit-commons.jar.
