Embedded resources in WML pages
The HTML samplers can automatically retrieve embedded images from web
pages, but it doesn't work for all XHTML pages or WML pages. I thought
I'd warn users about this, and bounce my solution off you good people.
JMeter determines whether a file is HTML by checking that its media type
is text/html. If it's something else, for example application/xhtml+xml,
application/xml, text/xml or text/vnd.wap.wml, then it won't try to
parse the file to retrieve embedded resources. So if you're trying to
test a WAP or XHTML application, JMeter may not be able to do what you
want.
As far as I can tell, this could be fixed most simply by changing
org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase as follows:
1. In downloadPageResources(), "text/html" is hardcoded. Either read a
list of allowed media types from properties, or hardcode a list of media
types. Maybe just allow any media type that contains "html" or "wml".
2. If parsing a WML page, ignore the configured parser and use
RegexpHTMLParser. (I guess the other parsers won't handle WML.)
Could some knowledgeable person confirm that this should work? If so, I
will hunt down a JDK and try to make it happen. If I can find time I
will try to submit a patch, but don't hold your breath...
Thanks,
Bennett.

Actually, don't bother creating a Bugzilla request...
It was easy enough to add the code, so please just check out the
nightly build 2-1.20060604 instead, and see if it works for you.
Configuration details are in jmeter.properties.

Sounds like a good idea.

Not sure about parsing WML pages - they seem to be rather different
from (X)HTML.
But it should not be too difficult to specify a different parser for
certain types of content - we could just add a wmlParser.classname
property alongside the htmlParser.classname.
Perhaps we could also add:
htmlParser.mimetypes
wmlParser.mimetypes
to specify the MIME media types that JMeter can handle, as well as
which is HTML and which is WML?

A Bugzilla enhancement would be useful...
