    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 returnbar Hello, world!whereas getInnerXML() would returnbar<baz>Hello, world!</baz>

    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); ?>
