Function to retrieve parent/child nodes

CWebguy

Does PHP have a function to retrieve parent/child nodes from an XML/RSS document? This would save having to change code everytime a new XML document is being used.

If that doesn't make sense. Does SimpleXML have a function to retrieve all fields that have 'x' in the field name. For instance, if I know that I want to retrieve a title field from 90% of the documents, but each one is different in structure, is there a simple code or function in PHP that will always pull the title regardless of the document's structure?

For example:

XML 1:
current->title

XML 2:
item->title

XML 3:
items-item->title

XML 4...and so on....

XML 5.....

All have the same node "title", but in different "places". Is there a way to successfully pull these with the same code for each one and not have to rewrite the code each time?

Thanks!

By the way, I have found this code:

foreach ($s->xsearch('//title') as $title) { 
    print "$title\n";
}

Which says that it should return all nodes with 'title', but it won't work 🙁 Does somebody have a solution? Thanks!

You should absolutely consult PHP Manual and read about
[man]simplexml[/man]
I am sure there numerous examples howto use simplexml functions.
Sometimes the most useful stuff/implementations are in the contributions in posted comments.
