I have used parent().parent(). But Alex's expression looks better.
Also, remember that you can use a separate function (that returns a boolean) to perform more complex logic. I have found that this sometimes is easier to keep track of than trying to do the whole expression inline. Approach this one step at a time. Use some temporary XML and XMLList variables, be verbose in the expressions, and use toXMLString() at every step, making sure you have what you expect.

I tried it without the klass node as I was miss reading the root, but that still didn't work. when I printout courseList.depts.dept.(name == needle) it returns all the name nodes like I expect but I want to get the klass node that is parented two levels up. Maybe it can't be done, most examples I've seen only return one parent node up from what they are searching for. be well, Hoyt --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Alex Harui" <[EMAIL PROTECTED]> wrote: > > Did you try: > > > > courseList.klass.(depts.dept.name==needle) > > > > ________________________________ > > From: [email protected] <mailto:flexcoders%40yahoogroups.com> [mailto:[email protected] <mailto:flexcoders%40yahoogroups.com> ] On > Behalf Of hoytlee2000 > Sent: Thursday, March 13, 2008 7:04 PM > To: [email protected] <mailto:flexcoders%40yahoogroups.com> > Subject: [flexcoders] Re: need help with XML predicate filtering > > > > Hmmm ... doesn't seem to work. > > When I use the parent() method nothing is returned: > > tempXMLList = > courseList.klass.depts.dept.(name==needle).parent().parent() > > --- In [email protected] <mailto:flexcoders%40yahoogroups.com> <mailto:flexcoders%40yahoogroups.com> > , "Tracy Spratt" <tspratt@> wrote: > > > > Immediate parent.
