问题描述
我正在尝试解析一个包含XML内容的字符串，该内容符合，Xerces2解析器支持解析XML 1.1文档。但是，我无法弄清楚如何告诉它我们试图解析的XML包含符合1.1的XML。
According the Xerces2 website, the Xerces2 parser supports parsing XML 1.1 documents. However, I cannot figure out how to tell it the XML we are trying to parse contains 1.1-compliant XML.
我正在使用DocumentBuilder来解析XML（某些东西）像这样）：
I'm using a DocumentBuilder to parse the XML (something like this):
public Element parseString(String xmlString) {
try {
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = dbf.newDocumentBuilder();
InputSource source = new InputSource(new StringReader(xmlString));
// Throws org.xml.sax.SAXParseException becuase of the invalid character refs
Document doc = documentBuilder.parse(source);
return doc.getDocumentElement();
} catch (ParserConfigurationException pce) {
// Handle the error
} catch (SAXException se) {
// Handle the error
} catch (IOException ioe) {
// Handle the error
}
}
我已尝试设置XML标头以指示XML符合1.1规范......
I've tried setting the XML header to indicate the XML conforms to the 1.1 spec...
xmlString = "<?xml version=\"1.1\" encoding=\"UTF-8\" ?>" + xmlString;
...但它仍然被解析为1.0 XML（仍然会生成无效的字符引用异常）。
...but it is still parsed as 1.0 XML (still generates the invalid character reference exceptions).
如何配置Xerces解析器以将XML解析为XML 1.1？是否有替代解析器为XML 1.1提供更好的支持？
How can I configure the Xerces parser to parse the XML as XML 1.1? Is there an alternative parser which provides better support for XML 1.1?
推荐答案
以获取xerces支持的所有功能的列表。可能低于2的功能是您必须打开的。
See here for a list of all the features supported by xerces. May be below 2 features is what you have to turn on.
http://xml.org/sax/features/unicode-normalization-检查
True：执行Unicode规范化检查（如第2.13节和XML 1.1建议书的附录B中所述）并报告规范化错误。
True: Perform Unicode normalization checking (as described in section 2.13 and Appendix B of the XML 1.1 Recommendation) and report normalization errors.
错误：不报告Unicode规范化错误。
False: Do not report Unicode normalization errors.
http://xml.org/sax/features/xml-1.1
True：解析器支持XML 1.0和XML 1.1。
False：解析器仅支持XML 1.0。
访问：只读
从：Xerces-J 2.7.0
注意：此功能的值取决于是否已知SAX解析器拥有的解析器配置支持XML 1.1。
True: The parser supports both XML 1.0 and XML 1.1.
False: The parser supports only XML 1.0.
Access: read-onlySince: Xerces-J 2.7.0Note: The value of this feature will depend on whether the parser configuration owned by the SAX parser is known to support XML 1.1.
