Hello,
I have an XML file which consists of a list of classes and it's
attributes (teacher, length, category, etc., etc., ...) Classes can
belong to different depts. I want to be able to grab all the classes
and their attributes that are part of a certain dept. The dept nodes
is a child of the class node. I can filter out the xml file to find
all the nodes whose dept value equals the dept I am looking for, but I
don't know how to return the main parent node.
here is the xml file :
<klasses>
<klass id="0">
<title>klass A</title>
<length unit="hr">1.5</length>
<category>core</category>
<depts>
<dept>
<name>art</name>
</dept>
<dept>
<name>pe</name>
</dept>
<dept>
<name>modeling</name>
</dept>
<dept>
<name>animation</name>
</dept>
</depts>
</klass>
<klass id="1">
<title>klass B</title>
<length unit="hr">1.5</length>
<category>core</category>
<depts>
<dept>
<name>r and d</name>
</dept>
<dept>
<name>td</name>
</dept>
<dept>
<name>lighting</name>
</dept>
<dept>
<name>matte painting</name>
</dept>
</depts>
</klass>
...
...
...
</klasses>
I get the xml file from:
courseList = evt.result.klass
// I want to get all klass objects that has "art" as one of the
dept.name nodes
var needle:String = "art"
I try using this predicate filter but it only returns a XMLLIst that
consists of <name>needle</name>
tempXMLList = courseList.klass.depts.dept.(name==needle)
what I want returned is:
<klass>
...
...
...
</klass>
<klass>
...
...
...
</klass>
...
...
...
where inside <klass> ... </klass> at least one of the dept.name nodes
is equal to "art"
I know it's probably simple but I can't seem to get the syntax right.
I've looked at a lot of examples but they don;t make sense to me and
most don't deal with anything deeper than a single level. I can't
seem to find any good documentation on predicate filtering either. I
appreciate any help, its kinda got me stuck from moving forward on
this development project.
I am still a novice on all this stuff.
Thanks.
be well,
Hoyt
