Either escape the double quotes with    String xmlString     lt element attribname   value   attribname1   value1   gt  pcdata lt  element gt     or use single quotes instead  String xmlString     lt element attribname  value  attribname1  value1  gt  pcdata lt  element gt

DocumentBuilder db   DocumentBuilderFactory newInstance   newDocumentBuilder    Document document   db parse new ByteArrayInputStream xmlString getBytes  UTF-8        remove the parameter UTF-8 if you don t want to specify the Encoding type    this works well for me even though the XML structure is complex   And please make sure your xmlString is valid for XML  notice the escape character should be added      at the front    The main problem might not come from the attributes
