My XML looks like :
<?xml version=\"1.0\"?>
<itemSet>
<Item>one</Item>
<Item>two</Item>
<Item>three</Item>
.....maybe more Items here.
</itemSet>
Some of the individual Item may or may not be present. Say I want to retrieve the element <Item>
two</Item>
if it's present. I've tried the following XPaths (in C#).
XMLNode node = myXMLdoc.SelectSingleNode("/itemSet[Item='two']")
--- If Item two is present, then it returns me only the first element one. Maybe this query just points to the first element in itemSet, if it has an Item of value two somewhere as a child. Is this interpretation correct?
So I tried:
XMLNode node = myXMLdoc.SelectSingleNode("/itemSet[Item='two']/Item[1]")
--- I read this query as, return me the first<Item>
element within itemSet that has value = 'two'. Am I correct?
This still returns only the first element one. What am I doing wrong?
In both the cases, using the siblings I can traverse the child nodes and get to two, but that's not what I am looking at. Also if two is absent then SelectSingleNode returns null. Thus the very fact that I am getting a successfull return node does indicate the presence of element two, so had I wanted a boolean test to chk presence of two, any of the above XPaths would suffice, but I actually the need the full element <Item>two</Item>
as my return node.
[My first question here, and my first time working with web programming, so I just learned the above XPaths and related xml stuff on the fly right now from past questions in SO. So be gentle, and let me know if I am a doofus or flouting any community rules. Thanks.]
