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.
It is important to note that internally, libxml uses the UTF-8 encoding and as such, the encoding of the retrieved contents will always be in UTF-8 encoding.
This extension requires the libxml PHP extension. This means that --enable-libxml needs to be used, although this will be done implicitly since libxml is enabled by default.
The XMLReader extension was initially a PECL extension for PHP 5. It was later moved to the PHP source (bundled) as of PHP 5.1.0, and later enabled by default as of PHP 5.1.2.
This extension is enabled by default and can be disabled through the following options when compiling: --disable-xmlreader
XMLReader::close — Close the XMLReader input
XMLReader::expand — Returns a copy of the current node as a DOM object
XMLReader::getAttribute — Get the value of a named attribute
XMLReader::getAttributeNo — Get the value of an attribute by index
XMLReader::getAttributeNs — Get the value of an attribute by localname and URI
##XMLReader::moveToNextAttribute — Position cursor on the next Attribute
XMLReader::next — Move cursor to next node skipping all subtrees
XMLReader::open — Set the URI containing the XML to parse
XMLReader::read — Move to next node in document
