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>
