public class InvalidXmlCharacterFilter
extends java.io.Reader

FilterInputStream that gets rid of characters that are invalid in an XML 1.0 document. Although these characters are forbidden, in the real wold they still appear in XML files. Java's SAX parser throws an exception, so we have to filter at a lower level. Only handles control characters (<0x20). Invalid characters are replaced by space (0x20).
