Enumerating XML Attribute Nodes

[James]

Hi,

I am trying to optimize some c# code that contains lots of code such as

String name = null;
try
{
name = myXMLElement.Attributes["name"].Value;
}
catch
{
}


[OK - I admit it - It's my code!]

The code needs optimizing, and I suspect throwing exceptions like this is
time consuming. Is there a better way to determine whether attribute node is
present other than the (obvious) enumeration of all the attributes. Has
anybody done any profiling to determine whether this approach is just as
inefficient?

What I'm really looking for is a "HasAttribute" function

Apologies if this has been asked a thousand times before.

XmlElement has HasAttribute() and GetAttribute()... if you know your
XmlNode is an element, then cast to XmlElement and you're sorted.

(and for info, you can call GetAttribute() even if it doesn't exist)
