The XML Encoding Trap

String xml = fileUtils.readTextFile("XMLfile.xml");

It's not a good idea to read an XML file and store it in a String because it wastes memory. The XML specifies its encoding in the XML header, so when you read a file, you need to know the encoding beforehand.

All XML parsers accept an InputStream as a parsing source and they correctly figure out the encoding themselves.
