I would like to reiterate that this does not work when compiled with versions of libxml lower than 20620. I found that it just presents a blank page. <?php $string = $reader->readString(); ?> I worked around this issue by adding the following helper function: <?php function read_string($reader) { $node = $reader->expand(); return $node->textContent; } ?> And then using: <?php $string = read_string($reader); ?>

For those who, like me, are having trouble figuring out the difference between getString() an getInnerXML(), the difference is that getString() does NOT include markup. So, for: <foo>bar<baz>Hello, world!</baz></foo> getString() on the <foo> node would return bar Hello, world! whereas getInnerXML() would return bar<baz>Hello, world!</baz>
