PHP XML Strategy: Parsing DOM to fill "Bean"
- by Mike
I have a question concerning a good strategy on how to fill a data "bean" with data inside an xml file.
The bean might look like this:
class Person
{
var $id;
var $forename = "";
var $surname = "";
var $bio = new Biography();
}
class Biography
{
var $url = "";
var $id;
}
the xml subtree containing the info might look like this:
<root>
<!-- some more parent elements before node(s) of interest -->
<person>
<name pre="forename">
Foo
</name>
<name pre="surname">
Bar
</name>
<id>
1254
</id>
<biography>
<url>
http://www.someurl.com
</url>
<id>
5488
</id>
</biography>
</person>
</root>
At the moment, I have one approach using DOMDocument. A method
iterates over the entries and fills the bean by "remembering"
the last node. I think thats not a good approach.
What I have in mind is something like preconstructing some xpath
expression(s) and then iterate over the subtrees/nodeLists. Return
an array containing the beans as defined above eventually.
However, it seems not to be possible reusing a subtree /DOMNode
as DOMXPath constructor parameter.
Has anyone of you encountered such a problem?
