Error Message from Inventory script

[claikind]

LibXMLError Object
(
    [level] => 3
    [code] => 4
    [column] => 1
    [message] => Start tag expected, '<' not found

    [file] => 
    [line] => 1
)

Can anyone tell me where this is coming from? I have looked at the script and cannot determine where the error could be.
