I have an XML structure that is 4 deep:

Now, I have both an FromAddress and a ToAddress that is parsed from an incoming email. I would like to do a LINQ query against a class set that was deserialized from this XML. For instance:
ToAddress =
[email protected]
FromAddress =
[email protected]
Query:
Get EmailRule.Include(Parse).Include(TargetPST) where address == ToAddress AND Parse.ToAddress==true AND Parse.useJustDomain==false
Get EmailRule.Include(Parse).Include(TargetPST) where address == [ToAddress Domain Only] AND Parse.ToAddress==true AND Parse.useJustDomain==true
Get EmailRule.Include(Parse).Include(TargetPST) where address == FromAddress AND Parse.FromAddress==true AND Parse.useJustDomain==false
Get EmailRule.Include(Parse).Include(TargetPST) where address == [FromAddress Domain Only] AND Parse.FromAddress==true AND Parse.useJustDomain==true
I am having a hard time figuring this LINQ query out. I can, of course, loop on all the bits in the XML like so (includes deserialization into objects):
XmlSerializer s =
new XmlSerializer(typeof(EmailRuleList));
TextReader r =
new StreamReader(path);
_emailRuleList = (EmailRuleList)s.Deserialize(r);
TargetPST[] PSTList = _emailRuleList.Items;
foreach (TargetPST targetPST in PSTList)
{
olRoot = GetRootFolder(targetPST.name);
if (olRoot != null)
{
Parse[] ParseList = targetPST.Items;
foreach (Parse parseRules in ParseList)
{
EmailRule[] EmailRuleList = parseRules.Items;
foreach (EmailRule targetFolders in EmailRuleList)
{
}
}
}
}
However, this means going through all these loops for each and every address. It makes more sense to me to query against the Objects. Any tips appreciated!
