- pxmllistContext
- IXMLDOMNodeList
The node that sets the context for the expression.
- bstrExpression
- String
The expression to be applied to each set of nodes in the specified context.
Returns
An object that represents the set of results calculated when the expression is applied to each set of elements in the context.
Examples
In the following example, the variable maxCost is set to the largest cost value, where cost is calculated by multiplying price by quantity.
IXMLDOMNodeList items = thisXDocument.DOM.selectNodes(@"/my:items/my:item");
decimal maxCost = (decimal) thisXDocument.Util.Math.Max((IXMLDOMNodeList) thisXDocument.Util.Math.<span class="label">Eval</span>(items, "price * quantity"));
Remarks
Note: Accessing the object returned by the Eval method by casting it to the IXMLDOMNodeList type in a managed form may result in security exceptions, in which case the form should be given FullTrust permissions.
