Validate XML before using itI am receiving XML (not a full document, just a node tree) from a remote
party and then inserting it into my bigger XML document using XmlWriter.WriteRaw(). The problem is that sometimes the XML from the remote party has invalid characters (such as \x17, \x08, etc). It is a known bug and they are working on it. But I need a quick solution ASAP to validate their XML before passing it into my WriteRaw because it puts my XmlWriter into a bad state (and it may take weeks for them to fix their code). Basically I just want to detect whether or not their XML is invalid, and if so, ignore it. What is the best way to do this? Thanks Create a schema definition and have them validate to that schema.

(c) Friedrich Nietzsche Yeah they are fixing the problem. The thing is I need a work-around, like,
right now, while they are working on it. I've tried stuff like setting CheckCharacters=false on the reader and writer. This causes the writer to no longer throw when writing, but the reader still throws.

making a new XmlWriter directed to that stream, and first testing XmlWriter.WriteRaw() on the null stream to validate whether or not the input XML is valid. Seems to work OK.
