Solution

This can be fixed by enabling RAMMFAR (runAllManagedModulesForAllRequests). The RAMMFAR setting is for per application. Enabling this option will enable all managed modules for all requests. That means static files such as images, PDFs and everything else will be processed by .NET

A smart solution is to add a new HTTP handler that looks for specific path criteria.

How to escape XML text in c#?

Escaping XML text is basically encoding the following symbols (<, >, &, ", ').

This can be done in the following ways.

a) Using Replace function

string xmlData = "I live in \"wellington\" & I love listening to music."
string escapedXmlData = xmlData.Replace("&", "&").Replace("<", "<").Replace(">", ">").Replace("\"", """).Replace("'", "&apos;");

Note: Replace the & symbol first.

b) Using System.Security.SecurityElement.Escape() method

string xmlData = "I live in \"wellington\" & I love listening to music."

string escapeXmlData = System.Security.SecurityElement.Escape(xmlData);

Data at the root level is invalid. Line 1, position 1

I got this error "Data at the root level is invalid. Line 1, position 1" when I tried to read an XML file using C#.

Initially I was checking whether the XML is well formed and tried opening in IE to make sure whether it opens fine. IE didn't show any errors and my XML document was fine.

I couldn't figure out what's gone wrong. After a few minutes I realised that I was using XML.LoadXML() instead of XML.Load().

Actually I had my code initially to load an XML string so I was using XML.LoadXML() but changed the logic to load an XML document but forgot to change the code to XML.Load().

XML.Load() - to load an XML File
XML.LoadXML() - to load a XML String
