XMLReader::open
A very simple way to avoid typing $reader->read() multiple times when you want to skip some nodes:
<?php
class smartXMLReader extends XMLReader {
public function readTimes($count) {
$i = 0;
while($i < $count){
$this->read();
$i++;
}
}
}
?>
Using this smartXMLReader,
<?php
$reader->readTimes(3);
?>
is equivalent to
<?php
$reader->read();
$reader->read();
$reader->read();
?>
Makes getting around in your XML document a bit easier :)

This class XMLReader2 is dangerous: charge all XML in memory, it can cause an out of memory error. It's the same that SimpleXML does.
Please take care.

If you have trouble parsing xml documents with text tags bigger than 10MB, this might help you:
<?php
$xmlreader = new XMLReader();
$xmlreader->open($uri, null, 1<<19);
?>
Since in libxml there is a constant
XML_PARSE_HUGE = 1<<19
which enables parsing xml documents with huge texts.
Please note that this option is not accessible using the setParserProperty method and that there is currently no constant to do the work, which will hopefully change soon:

libxml2 contains much more useful method readString() that will read and return whole text content of element. You can call it after receiving start tag (XMLReader::ELEMENT). You can use this PHP code to emulate this method until PHP will directly call underlying libxml2 implementation.
<?php
class XMLReader2 extends XMLReader
{
function readString()
{
$depth = 1;
$text = "";
while ($this->read() && $depth != 0)
{
if (in_array($this->nodeType, array(XMLReader::TEXT, XMLReader::CDATA, XMLReader::WHITESPACE, XMLReader::SIGNIFICANT_WHITESPACE)))
$text .= $this->value;
if ($this->nodeType == XMLReader::ELEMENT) $depth++;
if ($this->nodeType == XMLReader::END_ELEMENT) $depth--;
}
return $text;
}
}
?>
Just use XMLReader2 instead of XMLReader.
