XPath Query

P: n/a
OK, here's the deal. I have a small XML file that represents a small
database table. I load it into a System.XML.XMLDocument. So far so good.
I run an XPath query against it to retrieve all the field names. Everything
there works fine.

Here's my XML Document:

<?xml version="1.0" standalone="yes" ?>
<DataSet1 xmlns="http://www.tempuri.org/DataSet1.xsd">
<tblItem>
<ID>1</ID>
<Name>Spam</Name>
<Category>Food</Category>
<Description>Yummy! No natural ingredients</Description>
<Price>4</Price>
<ImageURL>images/1.png</ImageURL>
<LargeImageURL>images/L1.png</LargeImageURL>
</tblItem>
<tblItem>
<ID>2</ID>
<Name>Remote Control</Name>
<Category>Miscellaneous</Category>
<Description>Universal Remote</Description>
<Price>12</Price>
<ImageURL>images/2.png</ImageURL>
<LargeImageURL>images/L2.png</LargeImageURL>
</tblItem>
</DataSet>

Now for the tricky part. I'm trying to come up with three XPath queries
that will return the following:

1) All tblItem nodes that have a child ID node with a value of 1 (i.e., all
tblItem where ID = 1),
2) All tblItem nodes that have a Category of Miscellaneous (i.e., all
tblItem where Category = 'Miscellaneous')
3) All tblItem ndoes that have the word Remote in the Description (i.e., all
tblItem where Category contains the word 'Remote' in any position)

Coming from a SQL background, I'm having a hard time implementing XPath
expressions. I was hoping someone here could point me in the right
direction. I've tried several combinations, like "tblItem/ID[.='1']",
"tblItem[ID='1']" and "//tblItem[ID='Miscellaneous']". None of them seem to
be working though...

TIA
