XML or text declaration not at start of entity异常的原因

今天在做XML解析的时候，总是给我报

XML Parsing Error: XML or text declaration not at start of entity

?

的错误，后来查了下讲大概意思是android中解析的时候xml文件格式问题。

?

在文件的最前端 即<?xml version="1.0" encoding="UTF-8"?>前面不能有空格。

?

修改即好。

xml

  <?xml version="1.0" encoding="UTF-8" ?> - <msg>  <name>nico</name>   <des>male</des>   </msg>

ParserUtil

package com.nico;import java.io.InputStream;import org.xmlpull.v1.XmlPullParser;import org.xmlpull.v1.XmlPullParserException;import android.util.Xml;public class ParserUtil {private String myDes = " ";public String getDes(InputStream is){XmlPullParser parser = Xml.newPullParser();try {parser.setInput(is, "utf-8");int event = parser.getEventType();while(event!=XmlPullParser.END_DOCUMENT){switch(event){case XmlPullParser.START_TAG:String name = parser.getName();System.out.println("--------456---------->"+name);if("des".equals(name)){myDes = parser.nextText();return myDes;}break;}event = parser.next();}} catch (Exception e) {e.printStackTrace();}return myDes;}}

TestActivity
