xml - PHP return specific number of nodes? -

-

if have large xml file format:

<person>    <attribute>value</attribue> </person> <person>    <attribute>value</attribue> </person> <person>    <attribute>value</attribue> </person>

goes on hundreds of thousands of <person> records....

how can i, using php, echo out file/return 'person' 1-10, 11-20, etc..

i have found ton of examples (xpath, etc..) returning nodes or node subsets, no examples of returning specific range of nodes.

my specific file has hundreds of thousands of <person> nodes. want output in xml format <person>s 1-50,000, 50,001-100,000, etc...

turned out simple. couldn't find specific example online, managed piece few different examples needed:

<?php  $xml = simplexml_load_file('somexmlfile.xml');  $result = $xml->xpath('/enterprise/person[position()>=1 , position()<=10000]') ;  while(list( , $node) = each($result)) {     echo $node->asxml(); } ?>
