System.Xml.XmlException: hexadecimal value 0x02, is an invalid character

[Kannan]

I’m getting the following XmlException error through Elmah.

System.Xml.XmlException: '[1]', hexadecimal value 0x02, is an invalid
character. Line 1, position 175.


This doesn’t give any specific page in the stack track (see below) and
more over the weird thing is that it is happening at frequent interval
(say exactly at 15 minutes).


Here is the stack trace:

System.Xml.XmlException: '[1]', hexadecimal value 0x02, is an invalid
character. Line 1, position 175.

Could you please let me know how to resolve this?

Where are you getting this error from? I'm guessing something is
trying to pull down the RSS feed every 15mins?

Hi,

There is no specific page. All we have is the information from the
stack trace.

System.Xml.XmlException: ' ', hexadecimal value 0x02, is an invalid

character. Line 1, position 175.
at System.Xml.XmlTextReaderImpl.Throw(Exception e)
at System.Xml.XmlTextReaderImpl.Throw(String res, String[] args)
at System.Xml.XmlTextReaderImpl.ThrowInvalidChar(Int32 pos, Char
invChar)
at System.Xml.XmlTextReaderImpl.ParseNumericCharRefInline(Int32
startPos, Boolean expand, BufferBuilder internalSubsetBuilder, Int32&
charCount, EntityType& entityType)

....

Is there a way to disable the RSS feed update.

Also, this issue is not coming up on weekends. Its so weird that it
happens on Mon - Fri.

Same issue was logged in previous version & it was fixed by adding the
code "CheckCharacters = false" in 3 files. But in the latest code it
is available ony in ErrorXMLHandler.cs & not in other two error log
files.

Thanks,

SRK

RESOLVED:

Its the problem with RSS feed. One of the bookmarks on the browser for
checking the ELMAH log details was pointing to PROD & it was trying
to get the feed every 15 mins.

Once we removed the bookmark the error stopped.

Hope it helps.

Thanks,

SRK
