DOM XML Question

[PrivatePile]

Hello all.

Im writing a parser for an XML document using DOM. This is my first time. 😃 My question is this:

All i want to do is extract a single value from the file. This value is located in the following place:

- <root element>
   - <1st_element>
      - <2nd_element>
         - <1st_child_of_2nd_element>
         - <2nd_child_of_2nd_element>  [COLOR=red]<--- Im interested in the childeren of this one. [/COLOR]
      - </2nd_element>
      .
      .
      .

Now i know i could probably access that element using the following code, but recon there must be a simpler way.

$root = $doc->document_element();
$1st_element= $root->child_nodes();
$1st_element= $1st_element->first_child();
$2nd_element= $1st_element->child_nodes();
$2nd_element= $2nd_element->first_child();
$2nd_child_of_2nd_element= $2nd_element->child_nodes();
$2nd_child_of_2nd_element= $2nd_child_of_2nd_element->last_child();

Does anyone have any suggestiongs...?!?!
