我正在尝试解析来自 php 请求 URI 的 XML： http: //caracasfutbolclub.com/service/news.php。当我在解析字符串 xml 后做日志时，响应完成，一切看起来都很好，除了将 '<' 转换为 '& lt;' 等等所有的 HTML 标记（可能是一些 utf-8 问题或其他编码）。真正的交易是当我从节点请求元素时，正在检索“标题”XML 标记，但问题是“introtext”标记仅显示“<”而不是所有编码的 HTML标签内部：
注意：不只是显示，如果你在 "map.put("introtext", XMLfunctions.getValue(e, "introtext"));" 之后登录，你会得到整个字符串只是 <。
我正在使用的代码如下：
主要活动：
ArrayList<HashMap<String, String>> mylist = new ArrayList<HashMap<String, String>>();
String xml = XMLfunctions.getXML(); // method that is parsing the whole XML as a String.
Document doc = XMLfunctions.XMLfromString(xml);
Log.d("XML" , xml);
NodeList nodes = doc.getElementsByTagName("New");
for (int i = 0; i < nodes.getLength(); i++) {
HashMap<String, String> map = new HashMap<String, String>();
Element e = (Element)nodes.item(i);
map.put("title", XMLfunctions.getValue(e, "title"));
map.put("introtext", XMLfunctions.getValue(e, "introtext"));
map.put("created", "Publicado: " + XMLfunctions.getValue(e, "created"));
mylist.add(map);
}
XML函数：
public final static Document XMLfromString(String xml){
Document doc = null;
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
try {
DocumentBuilder db = dbf.newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader(xml));
doc = db.parse(is);
} catch (ParserConfigurationException e) {
System.out.println("XML parse error: " + e.getMessage());
return null;
} catch (SAXException e) {
System.out.println("Wrong XML file structure: " + e.getMessage());
return null;
} catch (IOException e) {
System.out.println("I/O exeption: " + e.getMessage());
return null;
}
return doc;
}
/** Returns element value
* @param elem element (it is XML tag)
* @return Element value otherwise empty String
*/
public final static String getElementValue( Node elem ) {
Node kid;
if( elem != null){
if (elem.hasChildNodes()){
for( kid = elem.getFirstChild(); kid != null; kid = kid.getNextSibling() ){
if( kid.getNodeType() == Node.TEXT_NODE ){
return kid.getNodeValue();
}
}
}
}
return "";
