Question

I am looking to create an expression tree by parsing xml using C#. The xml would be like the following:

<Expression> <If>   <Condition>     <GreaterThan>       <X>       <Y>     </GreaterThan>   </Condition>   <Expression /> <If> <Else>   <Expression /> </Else> <Expression> 

or another example…

<Expression>   <Add>     <X>     <Expression>       <Y>       <Z>     </Expression>   </Add> </Expression> 

…any pointers on where to start would be helpful.

Kind regards,

using System.Linq.Expressions; //in System.Core.dll  Expression BuildExpr(XmlNode xmlNode)  { switch(xmlNode.Name)     { case 'Add':        { return Expression.Add( BuildExpr(xmlNode.ChildNodes[0])                                ,BuildExpr(xmlNode.ChilNodes[1]));        }         /* ... */      }  }
