SharePoint CAML query error - The XML source is not correct

You may receive an error The XML source is not correct ... when working with CAML queries.

The CAML Query will fail for various reasons like – incorrect formatting, missing tokens, unexpected tokens, special characters, etc.

One case is where you are matching a value containing special characters (say CAML&SharePoint), you will receive an error, and the query will fail.

We can handle special characters by including the value to be matched within < ![CDATA[value]] >

<Eq><FieldRef Name="Title" /><Value Type="Text"><![CDATA[CAML&SharePoint]]> </Value>
