I am attempting to use SimpleXML to parse the xml file that is produced from the Google Reader export.
File example:
<?xml version="1.0" encoding="UTF-8"?>
<opml version="1.0">
<head>
<title>TheTechBox subscriptions in Google Reader</title>
</head>
<body>
<outline text="Engadget RSS Feed" title="Engadget RSS Feed"
type="rss" xmlUrl="http://www.engadget.com/rss.xml" htmlUrl="http://www.engadget.com"/>
<outline text="xkcd.com" title="xkcd.com" type="rss"
xmlUrl="http://xkcd.com/rss.xml" htmlUrl="http://xkcd.com/"/>
</body>
</opml>
This is what I have tried so far, the user uploads the file to this form and the form needs to loop through and extract the data.
<?php
if ($_FILES["file"]["error"] > 0)
{
echo "Error: " . $_FILES["file"]["error"] . "<br>";
}
else
{
$import = new SimpleXMLElement($_FILES["file"]["name"]);
foreach($import->opml->body->outline[0] as $feed){
echo $feed["title"];
}
}
?>
Right now chrome produces a server error which indicates something is very wrong on the page, the file uploads OK so it appears to be the simpleXML part.
I am planning to do something more complex with the data later, I am currently trying to get it just to echo the data on the page (for demo purposes).
Any feedback would be greatly appreciated.
Here is the working code in the end
$import = simplexml_load_file($_FILES["file"]["tmp_name"]);
foreach($import->body->outline as $feed){
echo $feed["title"];
}
This will need adding to to parse all of the data but this works.
You've fallen into a classic trap when using SimpleXML: the first object you get when parsing a file or string is not an abstract "document" object, but the parent node. In this case, the parent node is <opml> ... </opml>, so $import in your sample code is that <opml> node. In other words, rather than $import->opml->body you just need to say $import->body.
There's another bug in your loop as well, which is that you are asking for the first <outline> element (->outline[0]) when what you want is to be looping over all of the elements (foreach( $whatever->outline as $feed )).
