Find XmlElement in List using array of matching attribute names … Using Linq?

You can use All() to match several attributes and GetAttribute() to avoid having to check for null : public static IEnumerable FindMatchingElements(XmlElement match, IEnumerable elements, params string attributeNames) { // Argument validation omitted for brevity. Return elements. Where( element => attributeNames.

All( name => element. GetAttribute(name) == match. GetAttribute(name))); } That said, if you really want to parse or generate XML markup with LINQ, consider using LINQ to XML instead of the DOM classes.

Édéric, Thanks for your response. I had to change '. Attributesname' to '.Attributesname.

Value' to get it to work, but that means I now get an error if I specify an attribute in the params that is not present on the match element..?! – user597118 Jun 2 at 10:15 @user597118, you're absolutely right about . Value (I'm not used to XmlElement anymore, too much LINQ to XML I guess).

I updated my answer to use GetAttribute() instead, which will return the empty string if the attribute is not present. – Frédéric Hamidi Jun 2 at 10:25 édéric, Awesome thanks! It is nice to be right about something, just don't tell my missus :-) I am just reading up on Linq to Xml and can already see the advantages... thanks for the link and necessary kick up the a**e!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
