XPATH syntax to select products from XML

[ChristianRider14]

I have the following XPATH which seems to be selecting out the correct products for the category but is incorrectly selecting products when they have a qtyInStock value of 0 when in my XPath I state qtyInStock > 0. Can anyone see what is wrong with this, I assume my syntax is incorrect.\[quote\] /products/product[category = 1234 or additionalCategories/catID =1234 and qtyInStock > 0]\[/quote\]\[code\]<?xml version="1.0" encoding="UTF-8"?><products><product><prod_id>2100818</prod_id><productURL></productURL><productImageURL>jb-m-kirichigai-draw-6.jpg</productImageURL><category>448267</category><qtyInStock>2</qtyInStock><featured>1</featured><Hidden>0</Hidden><productName>1.5 Sun Kirichigai 6 Step with Draw Japanese Puzzle Box</productName><livePrice>39.4</livePrice><fullURL>http://www.faze3.co.uk/index.aspx?pageID=527917&prodID=2100818</fullURL></product><product><prod_id>2101600</prod_id><productURL></productURL><productImageURL>jb-2-kiasa-7.jpg</productImageURL><category>448267</category><qtyInStock>1</qtyInStock><featured>1</featured><Hidden>0</Hidden><productName>2 Sun Kiasa 7 Step Japanese Puzzle Box</productName><livePrice>28.4</livePrice><fullURL>http://www.faze3.co.uk/index.aspx?pageID=527917&prodID=2101600</fullURL></product><product><prod_id>2101795</prod_id><productURL></productURL><productImageURL>jb-2-koyosegi-7.jpg</productImageURL><category>448267</category><qtyInStock>2</qtyInStock><featured>1</featured><Hidden>0</Hidden><productName>2 Sun Koyosegi 7 Step Japanese Puzzle Box</productName><livePrice>25.95</livePrice><fullURL>http://www.faze3.co.uk/index.aspx?pageID=527917&prodID=2101795</fullURL></product><product><prod_id>2102219</prod_id><productURL></productURL><productImageURL>jb-2-kuroasa-10.jpg</productImageURL><category>448267</category><qtyInStock>0</qtyInStock><featured>1</featured><Hidden>0</Hidden><productName>2 Sun Kuroasa 10 Step Japanese Puzzle Box</productName><livePrice>34.8</livePrice><fullURL>http://www.faze3.co.uk/index.aspx?pageID=527917&prodID=2102219</fullURL></product>\[/code\]
