我有一个org.w3c.dom.Document
,并希望使用此功能对其进行序列化,但是却得到一个SAXException
。我该如何解决?
public static String serializeXmlDocument(Document document) throws Exception
{
// set up a transformer
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer trans = transformerFactory.newTransformer();
trans.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
trans.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
trans.setOutputProperty(OutputKeys.INDENT, "yes");
DOMSource source = new DOMSource(document);
// create string from xml tree
StringWriter stringWriter = new StringWriter();
StreamResult stringResult = new StreamResult(stringWriter);
trans.transform(source, stringResult);
return stringWriter.toString();
}
这将导致以下错误:

最佳答案
该文档包含无效的Unicode字符,例如
http://www.fileformat.info/info/unicode/char/d835/index.htm
我用removing invalid XML characters from a string in java中的解决方案修复了它
// remove illegal unicode characters
String xml10pattern = "[^"
+ "\u0009\r\n"
+ "\u0020-\uD7FF"
+ "\uE000-\uFFFD"
+ "\ud800\udc00-\udbff\udfff"
+ "]";
stringValue = stringValue.replaceAll(xml10pattern, " ");
