Need Help With XML Parsing Logic.. plz ?

[acidbox]

Basically, I have an XML file and I am able to parse it fine, however, I am stuck on a stumbling block that is preventing me from displaying the output that I would like.

The XML code I am pulling from is similar to the following:

<Result>
     <ResultID>1</ResultID>
      <Name>Bob Smith</Name>
     <ResultID>2</ResultID>
      <Name>John Doe</Name>
     <ResultID>3</ResultID>
      <Name>Joe Smith</Name>
</Result>
<Result>
     <ResultID>1</ResultID>
      <Name>Robert Wilson</Name>
     <ResultID>Leroy Brown</ResultID>
      <Name>Bob Smith</Name>
     <ResultID>3</ResultID>
      <Name>John Davis</Name>
     <ResultID>4</ResultID>
      <Name>Mike Jones</Name>
</Result>

That said, I know how to find out how many rows of <Result> there are, and I know how to find out how many rows of <ResultID> there are, but I DON'T know how to find out how many rows of <ResultID> there are for each <Result>

Does anyone know how I might construct the logic to complete this task?

Note: I am using the following code to parse my XML files: http://www.zend.com/codex.php?id=380&single=1

Within This code, you will find this function, which is how I am currently determining how many rows of each tag are returned:

<?php
function get_element_rows($element){ 
    return count($this->array_element[$element]); 
}
?>

I am really stuck on this one...

Well, i've made SOME progress. So far, I have created a function that baiscally detects if the ResultID rolls over to 1. If that is the case, it returns the number of results to display. However, it is not working correctly. Here is the code:

<?php

function get_sub_element_rows($element,$ind = 0){ 

$start_ind = 0;

while ($this->array_element[$element][$ind] != $start_ind AND $this->array_element[$element][$ind] != "")
	{
		$start_ind = 1;
		$ind++;
	}
return $ind;
} 

?>

I call this function from within a for loop such as this:

<?php

for ($s = 0; $s < $xml->get_element_rows("Result"); $s++)
	{
		if (!$old_num_rows)
			{
				$old_num_rows == 0;
			}
		$num_rows = $xml->get_sub_element_rows("ResultID", $old_num_rows);
		$old_num_rows = $old_num_rows + $num_rows;
	}

?>

Now, for a test example, I used an XML file with 4 <Result> Tags as follows:

<Result>
	<ResultID>1</ResultID>
</Result>
<Result>
	<ResultID>1</ResultID>
	<ResultID>2</ResultID>
	<ResultID>3</ResultID>
</Result>
<Result>
	<ResultID>1</ResultID>
	<ResultID>2</ResultID>
</Result>
<Result>
	<ResultID>1</ResultID>
	<ResultID>2</ResultID>
	<ResultID>3</ResultID>
	<ResultID>4</ResultID>
</Result>

I ran this through the script, and at the beginning of the for loop, I echoed the values of $num_rows and $old_num_rows

Here are the results:

old_num_rows: 0
num_rows: 1

old_num_rows: 1
num_rows: 4

old_num_rows: 5
num_rows: 6

old_num_rows: 11
num_rows: 11

This is not correct. The difference between $num_rows and $old_num_rows should be exactly how many <ResultID> tags are under each <Result> tag. It appears to work for the first 2 results, but after that it becomes really screwed up. I know it has to be something simple, but my brain is fried right now.

Can anyone out here help me with this? I am really losing my mind. Thanks in advance.

bump.

The solution to this problem doesn't have to be based on MY suggestion. I am open to any possible method of determining how to find the number of nested <ResultID> for each <Result> tag. If anyone can help, I'd appreciate it.
