I am trying to extract keywords and image urls from this xml document (also attached)
http://www.powerhousemuseum.com/collection/database/opensearch/new_tlf_feed.php?start=1&show=3

It contains 3
/rss/channel/item elements
each containing one
/general element
each general element contains many keyword elements
each of which has a string element who's value i want.

I can get XPathNodeIterator on /rss/channel/item
with the correct count

And I can get an XPathNodeIterator on * on all of the item elements

But I cant seem to get a XPathNodeIterator on /general/keyword
inside of item

I have considered that general has an xmlns assigned to it but I want to grab all general elements regardless of their namespace. Any help would be great.

Additionally inside each item I would like to grab
/relation(2nd element)/resource/identifier/entry

I have been using these two pages as help with no luck
http://msdn.microsoft.com/en-us/library/ms256086(VS.80).aspx
http://msdn.microsoft.com/en-us/library/ms256095(VS.80).aspx

Thank you for any help or direction you can provide

				<string language="en">Botanical model, lilac (Syringa vulgaris), papier-mache / wood, made by Louis Thomas Jerome Auzoux, purchased from Chretian Vetter, Hamburg, Germany, 1865-1884

Botanical model of a lilac made of painted papier-mache and mounted on a circular wooden stand. The lilac features a tall stem that is removable in two parts. The green section of the stem can be removed from the wooden stand, while the flower itself can be removed from the stem to show an internal, pale green bud. The flower is light purple in colour with four open, drooping petals and pollen in the centre. The papier-mache is cracking around the narrow section of the petals.</string>

						<string language="en">In the second half of the nineteenth century interest in the anatomical structure of the animal and vegetable world increased markedly. This led to problems acquiring human bodies for educational purposes and zoological and botanical specimens from the more remote parts of the globe. As a result there was an increased demand for models which were structurally correct and robust enough to withstand the classroom environment.

						<string language="en">Traditionally wax had been used to make models but wax models were delicate and susceptible to changes in temperature, which could cause them to melt or lose their shape. One response was the introduction in the nineteenth century of papier-m&#226;ch&#233; to make structural models of all kinds of objects found in nature. Modellers found papier-m&#226;ch&#233; more robust and it enabled craftsmen to fashion models in sections that could be removed in layers as if a real dissection were taking place.

						<string language="en">A pioneer of this form of modelling was Louis Thomas J&#233;rome Auzoux (1797-1880) a French medical graduate. Around 1820 he visited the workshop of Jean-Francois Ameline, who had introduced papier-m&#226;ch&#233; to the modelling process. Auzoux soon learnt the process and set up a workshop in his home town of Saint Aubin d'Ecrosville in 1827. His medical background enabled him to make highly accurate models while his experiments with papier-m&#226;ch&#233; resulted in the development of a variety of finishes which incorporated plaster, fabric and glass. The other aspect of Auzoux's success was his application of moulding techniques which allowed him to produce models in larger numbers.

						<string language="en">A common feature of many of Auzoux's models is the use of paint on a thin plaster layer which covered the papier-m&#226;ch&#233;. Studio artists were employed to add the finishing touches using egg tempura, which gave a shiny gloss to the finished work. Iron supports were included to reinforce the delicate areas of some models, and metal was sometimes used to connect parts.

						<string language="en">In 1865 Auzoux introduced a new line of large-scale botanical models for educational use. These were made using Auzoux's papier-m&#226;ch&#233; moulds and painted plaster. Their exaggerated size allowed students to examine tiny details more easily than in often fragile botanical specimens. Another advantage was the fact that real specimens preserved in alcohol tended to lose their colour while Auzoux's painted models enabled students to get an idea of their colour in real life. Dr. Auzoux's models were acclaimed throughout Europe.

						<string language="en">Although Auzoux used moulds to make multiple copies of his models, they were still extremely labour intensive and as a result were never produced in large numbers. Today these models are highly sought after by collectors and museums not only for their place in the history of the medical and natural sciences but also as works of art in their own right. This model is part of the Powerhouse Museum's original collection and illustrates the importance placed on educational models during the museum's formative years. This model was purchased from the German dealer Chr&#233;tian Vetter in 1884, some four years after Auzoux had died.
