SQL Server Select LEN on XML

What is the best way for me to get a true "Length" on an XML field that was inserted using a HttpWebResponse chunked response and a read buffer like this in VB
streamRead.Read(readBuff, 0, 5120)


This is my select
SELECT LEN(CAST(XmlDoc AS VARCHAR(MAX))) xmlDoc FROM      [dbo].[VOIPXMLTransactionLog]

But it seems to be ignoring spaces?

Are you sure that spaces are in the variable?
Where are you openinig your file? Maybe in a "visual" editor (just like Internet Explorer)? If so, you may see spaces where there are only tabs, or maybe nothing...
Some viewers/editors apply formatting to XML files.
Please ensure you are not in this case...

I'm not looking at it in a viewer.

I'm getting a response stream and sending it straight to SQL Server.

that SQL statement looks fine. LEN does take into account spaces so this should give you the result you are looking for. Why do you think it is not working as intended? The only thing I can think of is that LEN does not count trailing spaces!

as a side note, you can also use the function datalength which returns the size in bytes, including trailing blanks:
