Stripping Invalid XML characters in Java

Question

I have an XML file that\'s the output from a database. I\'m using the Java SAX parser to parse the XML and output it in a different format. The XML contains some invalid c

Answer 1

I used Xalan org.apache.xml.utils.XMLChar class:

public static String stripInvalidXmlCharacters(String input) {
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i < input.length(); i++) {
        char c = input.charAt(i);
        if (XMLChar.isValid(c)) {
            sb.append(c);
        }
    }

    return sb.toString();
}
