(PHP 5 >= 5.2.0, PHP 7)
XMLReader::readString — Reads the contents of the current node as a string
Reads the contents of the current node as a string.
This function has no parameters.
Returns the content of the current node as a string. Empty string on failure.
This function is only available when PHP is compiled against libxml 20620 or later.
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); ?>
