XMLReader::readString — Lee el contenido del nodo actual como string
Lee el contenido del nodo actual como string.
Esta función no contiene ningún parámetro.
Devuelve el contenido del nodo actual como cadena. En caso de error devuelve una cadena vacía.
Esta función solo está disponible si PHP es compilado utilizando la biblioteca libxml 20620 o posterior.
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); ?>
