If I use simplexml_load_string to create an XML object with the

I get this SimpleXMLElement back

but I cannot seem to get anything out of an xpath expression, no matter
what I try.
If, however, I remove the 'xmlns=http://www.w3.org/1999/xhtml;' in the
html element, it works fine. So yeah, I can just remove that text,
but... is there something wrong here, in my expectation or in the xpath
function?
TIA.

Gary,
I am not sure what you have tried, but namespaces change everything in
XPath compared to documents without them. This isn't exact, but XPath
without namespaces is often simple such as:
/html/head/title
Once you add a namespace, though, the XPath becomes something like
/*[namespace-uri()='http://www.w3.org/1999/xhtml' and
local-name()='html']/*[namespace-uri()='http://www.w3.org/1999/xhtml'
and local-name()='head']/*[namespace-uri()='http://www.w3.org/1999/xhtml'
and local-name()='title']
(I'm not sure of the exact syntax since I don't have something open
right now that I can test it in.
However, I think SimpleXML has some features that make this easier.
Take a look at this:
