XmlDocument.Loadxml System.Xml.XmlException: Name cannot begin with the '8' character - xml from imageglue

Question

I'm using ImageGlue to read Exif data from an image. ImageGlue gets the exif data successfully and returns an xml string. When I try to use an XMLDocument to load the xml string, it throws the error:

Name cannot begin with the "8" character".

I know what part of the xml is causing the error, but I don't know if it is an issue with the xml, or the xmldocument object trying to load. The xml is below, the tag causing the error is the last one: Industries, Inc. It doesn't like the "8298", if I remove it, it works fine. Is it ImageGlue's issue not generating the right xml from the Exif, or is the XmlDocument object (C#) not reading it correctly...?

Answer 1

That's invalid XML - it's ImageGlue not generating the right XML. It is trying to use an XML tag name of "Tag 8298", but the space doesn't work in there, meaning the 8298 is interpreted as an attribute name, which cannot begin with a digit.
