Validate string as XML in Java

String strXML ="<?xml version='1.0' encoding='UTF-8' standalone='yes'?><custDtl><name>abc</name><mobNo>9876543210</mobNo></custDtl>"

how to validate whether the string is a proper XML String.

Solution

  • You just need to open an InputStream based on the XML String and pass it to the SAX Parser:

    try {
    String strXML ="<?xml version='1.0' encoding='UTF-8' standalone='yes'?><custDtl><name>abc</name><mobNo>9876543210</mobNo></custDtl>";
    SAXParser saxParser = SAXParserFactory.newInstance().newSAXParser();
    InputStream stream = new ByteArrayInputStream(strXML.getBytes("UTF-8"));
    saxParser.parse(stream, ...);
} catch (SAXException e) {
    // not valid XML String
}
