Hi I am trying to extract the value in an XML node/element as an

is a snip of what the xml looks like.
<BlastOutput_iterations>

<Iteration_iter-num>1</Iteration_iter-num>
<Iteration_hits>
<Hit>
<Hit_num>1</Hit_num>
<Hit_id>gi|229264291|gb|CP001598.1|</Hit_id>

<Hit_accession>CP001598</Hit_accession>

What I need to get at is the number for <Hit_len> and others in the
file. I
know this must be an easy thing to do I just cannot find a simple
way to do
it. Any ides...? Thanks
If it really looks this, like you should be able to feed your XML to
NSXMLElement's 'initWithXMLString:error:'. Then use 'elementsForName:'
to descend though the hierarchy and use 'attributeForName:' to get the
attribute you want.
(If you have an entire XML document, you might need to parse it with a
NSXMLDocument and descend from its 'rootElement' instead.)
