The XMLReader class

(PHP 5 >= 5.1.0, PHP 7, PHP 8)

Introduction

The XMLReader extension is an XML Pull parser. The reader acts as a cursor going forward on the document stream and stopping at each node on the way.

The "XML2Assoc" functions noted here should be used with caution... basically they are duplicating the functionality already present in SimpleXML. They may work but they won't scale.

Their are two main uses cases for parsing XML, each suited to either XMLReader or SimpleXML.

1. SimpleXML is an excellent tool for easy access to an XML document tree using native PHP data types. It starts to flounder with massive (> 50M or so) XML documents, as it reads the entire document into memory before it can be processed. SimpleXML will just laugh at you then die when your server runs out of memory (or it will cause a load spike).

2. Aside from the reasoning behind massive XML documents, if you have to deal with massive XML documents, use XMLReader to process them. Don't try and gather an entire XML document into a PHP data structure using XMLReader and a PHP xml2assoc() function, you are reinventing the SimpleXML wheel.
When parsing massive XML documents using XMLReader, gather the data you need to perform an operation then perform it before skipping to the next node. Do not build massive data structures from a massive XML document, your server (and it's admins) will not like you.

Sometimes you have an unusual URL that doesn't actually point to an xml file but still returns xml as output (Like the Battlefield Heroes generated syndication urls). Using get_file_contents(url) you can retrieve the xml data from these urls and pass it as a variable for processing as an XML String.

Unfortunately simpleXML or xml DOM cannot process all xml strings. Some have error boxes added to the end of them (such as Battlefield Heroes syndicated news). These boxes cause an end of file sort of error and closes out the script. XMLReader grabs data from these strings without error.

Guys, I hope this example will help
you can erase prints showing the process-
and it will be a piece of nice code.

<?php
function xml2assoc($xml, $name)
{
print
"<ul>";

$tree = null;
print(
"I'm inside " . $name . "<br>");

while(
$xml->read())
{
if(
$xml->nodeType == XMLReader::END_ELEMENT)
{
print
"</ul>";
return
$tree;
}

else if(
$xml->nodeType == XMLReader::ELEMENT)
{
$node = array();

print(
"Adding " . $xml->name ."<br>");
$node['tag'] = $xml->name;

if(
$xml->hasAttributes)
{
$attributes = array();
while(
$xml->moveToNextAttribute())
{
print(
"Adding attr " . $xml->name ." = " . $xml->value . "<br>");
$attributes[$xml->name] = $xml->value;
}
$node['attr'] = $attributes;
}

if(!
$xml->isEmptyElement)
{
$childs = xml2assoc($xml, $node['tag']);
$node['childs'] = $childs;
}

print(
$node['tag'] . " added <br>");
$tree[] = $node;
}

else if(
$xml->nodeType == XMLReader::TEXT)
{
$node = array();
$node['text'] = $xml->value;
$tree[] = $node;
print
"text added = " . $node['text'] . "<br>";
}
}

print
"returning " . count($tree) . " childs<br>";
print
"</ul>";

return
$tree;
}

echo
"<PRE>";

$xml = new XMLReader();
$xml->open('test.xml');
$assoc = xml2assoc($xml, "root");
$xml->close();

print_r($assoc);
echo
"</PRE>";

?>

It reads this xml:

<test>
<hallo volume="loud"> me <br/> lala </hallo>
<hallo> me </hallo>
</test>

Found this in the IXmlReader docs at msdn but it's also valid for XMLReader in PHP.

You should save the value of $isEmptyElement before processing attributes, or call moveToElement to make $isEmptyElement valid after processing attributes.

$isEmptyElement returns FALSE when XMLReader is positioned on an attribute node, even if attribute's parent element is empty.

As japos mentioned. Take care how you use isEmptyElement. After you are done looping through the attributes: isEmptyElement will be false. You can use moveToElement() to move the cursor back to the element and then you can use isEmptyElement like normal again.

Take care about how to use XMLReader::$isElementEmpty. I don't know if it is a bug or not, but $isElementEmpty is set for the current context and NOT just for the element. If you move your cursor to an attribute, $isElementEmpty will ALWAYS be false.

<?php
$xml
= new XMLReader();
$xml->XML('<tag attr="value" />');
$xml->read();
var_dump($xml->isEmptyElement);
$xml->moveToNextAttribute();
var_dump($xml->isEmptyElement);
?>

will output

(bool) true
(bool) false

So be sure to store $isEmptyElement before moving the cursor.

To verify that all nodes are read without error/warning you can use this code:
<?php
$endofxml
= false;
$xml_url = "example.xml";
$reader = new XMLReader();
if(!
$reader->open($xml_url)){
print
"Error to open XML: $xml_url\n";
} else {
while (
$reader->read()) {
$firstnode = (!isset($firstnode)) ? $reader->name : $firstnode;
/*
DO SOMETHING
*/
if ($reader->nodeType == XMLReader::END_ELEMENT && $reader->name == $firstnode) {
$endofxml = true;
}
}
}
if(
$endofxml) {
print
"no error found";
} else {
print
"error found";
}
?>

This code is useful to trap $reader->read() error/warning.

XML to ASSOCIATIVE ARRAY

Improved algorithm based on Sergey Aikinkulov's. The problem was that it would overwrite nodes if they had the same tag name. Because of that <a><b/><b/><a> would be read as if <a><b/><a/>. This algorithm handles it better and outputs an easy to understand array:

<?php
function xml2assoc($xml) {
$tree = null;
while(
$xml->read())
switch (
$xml->nodeType) {
case
XMLReader::END_ELEMENT: return $tree;
case
XMLReader::ELEMENT:
$node = array('tag' => $xml->name, 'value' => $xml->isEmptyElement ? '' : xml2assoc($xml));
if(
$xml->hasAttributes)
while(
$xml->moveToNextAttribute())
$node['attributes'][$xml->name] = $xml->value;
$tree[] = $node;
break;
case
XMLReader::TEXT:
case
XMLReader::CDATA:
$tree .= $xml->value;
}
return
$tree;
}

?>

Usage:

myxml.xml:
------
<PERSON>
<NAME>John</NAME>
<PHONE type="home">555-555-555</PHONE>
</PERSON>
----

<?
$xml = new XMLReader();
$xml->open('myxml.xml');
$assoc = xml2assoc($xml);
$xml->close();
print_r($assoc);
?>

Outputs:
Array
(
[0] => Array
(
[tag] => PERSON
[value] => Array
(
[0] => Array
(
[tag] => NAME
[value] => John
)

[1] => Array
(
[tag] => PHONE
[value] => 555-555-555
[attributes] => Array
(
[type] => home
)

)

)

)

)

For reasons that have to do with recursion, it returns an array with the ROOT xml node as the first childNode, rather than to return only the ROOT node.
