Problem with parsing XML file in PHP

zomby_pengy · April 19, 2008, 4:47pm

I’m using XML and PHP to make a “news” portion of a website… the xml looks like:

it works for the most partm but the thing is that when I put some data in the <content></content> tags that consists of alot of text, the parser doesn’t work correctly…

here is my xml file:

<?xml version="1.0" encoding="iso-8859-1"?>
<news>
    <story>
        <id>1</id>
        <title><![CDATA[hmmm...]]></title>

        <date>04/19/08</date>
        <summary><![CDATA[Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Praesent tortor neque, malesuada id, phare...]]></summary>

and here is the php file:

and when the xml file is done parsing, and I do a print_r(); on the array $story_array, this is what prints out…

for some reason it is splitting the data in the <content></content> tags into a couple of paragraphs and putting the second two sections in the array as an object of itself…

[headline] => hmmm…
