如何替换＆，<字符为&,<解析后的xml文件为android？

Question

这里是我想改变我的XML文件的一部分...... 这个文件并不存储在我的项目的资产，它是在网络 xml文件我用了XMLPull解析器解析

参照此：XmlPullParser

你在寻找这样的事情：

if(eventType == XmlPullParser.TEXT) 
{ 
    String text = xpp.getText(); 
    if(text.contains("&")) 
     text = text.replace("&", "&"); 
    if(text.contains("<")) 
     text = text.replace("<", "&lt;"); 
} 

编辑： 这里是你如何获取XML在String：

String xmlStr = ""; 

HttpGet uri = new HttpGet(params[0]); 

DefaultHttpClient client = new DefaultHttpClient(); 

HttpResponse resp = client.execute(uri); 
StatusLine status = resp.getStatusLine(); 
if(status.getStatusCode() == 200) 
{ 
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); 
    DocumentBuilder builder = factory.newDocumentBuilder(); 
    Document doc = builder.parse(resp.getEntity().getContent()); 

    TransformerFactory transformerfactory = TransformerFactory.newInstance(); 
    Transformer transformer = transformerfactory.newTransformer(); 
    transformer.setOutputProperty(OutputKeys.INDENT, "yes"); 

    StringWriter stringWriter = new StringWriter(); 
    transformer.transform(new DOMSource(doc), new StreamResult(stringWriter)); 

    // Now you can fix the invalid characters in your xml and put it in the parser 
    xmlStr = stringWriter.toString(); 
}
