    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>

    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); ?>

    Important:
    When using it use -> instead of ::.
    You have to use :: only on static functions and then you have not to create a class object.
