hey,
got this code writing to an xml file but it wont apend it just keeps goin over the same one, basically at the end of it i want a list of all the different enteries so i can take out information afterwards. need to do this with PHP and XML!
here's the code!
#!/usr/dist/bin/php
<?php
if( ! ($fp = fopen( "sponsor1.xml" , "r" )) )
die("Couldn't open xml file!");
$person_counter = 0;
$person_data = array();
$xml_current_tag_state = '';
function startElementHandler( $parser, $element_name, $element_attribs )
{
global $person_counter;
global $person_data;
global $xml_current_tag_state;
if( $element_name == "STORY" )
{
// $person_data[$person_counter]["author"] = $element_attribs["AUTHOR"];
}
else
{
$xml_current_tag_state = $element_name;
}
}
function endElementHandler( $parser, $element_name )
{
global $person_counter;
global $person_data;
global $xml_current_tag_state;
$xml_current_tag_state = '';
if( $element_name == "STORY" )
{
$person_counter++;
}
}
