问题描述

在做项目实训，遇到Xml解析的问题

运行时出现这样的问题setInput() must be called first. (position:START_DOCUMENT null@1:1)

<?xml version=""1.0"" encoding=""UTF-8""?>-<Response>-<Error><ErrorCode>0</ErrorCode></Error>-<Data>-<UserBean><Id>269</Id><Gender>1</Gender><Department>1</Department><Email>1234567＠163.com</Email><Age>11</Age></UserBean></Data></Response>

我的代码是：

public class XmlRegist extends XmlGridParser {

 boolean isLoginfo = false; boolean isName = false; boolean isGender = false; boolean isDepart = false; boolean isPass = false; boolean isEmail = false; boolean isAge = false;public XmlRegist(InputStream is XmlPullParser parser) throws ParseException {    super(is parser);}protected void handleExtraElementInEntry(EntryP entry)        throws XmlPullParserException IOException ParseException {    XmlPullParser parser = getParser();    if (!(entry instanceof EntryLogin)) {        throw new IllegalArgumentException(""Expected EntryRegist!"");    }    EntryRegist regist = (EntryRegist) entry;    int type = parser.getEventType();    try    {        while (type != XmlPullParser.END_DOCUMENT)        {            String name = parser.getName();           switch( type)           {           case XmlPullParser.START_DOCUMENT:               break;           case XmlPullParser.START_TAG:           {if(name.equals(""Data""))           {            if (type == XmlPullParser.START_TAG                    && name.equals(regist.USERBEAN)) {            if (type == XmlPullParser.START_TAG && name.equals(regist.LOFINFO))            {                isLoginfo = true;            } else if (type == XmlPullParser.END_TAG&& name.equals(regist.LOFINFO)) {                isLoginfo = false;            }            else if(type==XmlPullParser.START_TAG&&name.equals(regist.NAME))            {                isName=true;            }else if(type==XmlPullParser.END_TAG&&name.equals(regist.NAME))            {                isName=false;            }            else if(type==XmlPullParser.START_TAG&&name.equals(regist.GENDER))            {                isGender=true;            }else if(type==XmlPullParser.END_TAG&&name.equals(regist.GENDER))            {                isGender=false;            }            else if(type==XmlPullParser.START_TAG&&name.equals(regist.DEPART))            {                isDepart=true;            }else if(type==XmlPullParser.END_TAG&&name.equals(regist.DEPART))            {                isDepart=false;            }            else if(type==XmlPullParser.START_TAG&&name.equals(regist.PASS))            {                isPass=true;            }else if(type==XmlPullParser.END_TAG&&name.equals(regist.PASS))            {                isPass=false;            }            else if(type==XmlPullParser.START_TAG&&name.equals(regist.AGE))            {                isAge=true;            }else if(type==XmlPullParser.END_TAG&&name.equals(regist.AGE))            {                isAge=false;            }            else if (type == XmlPullParser.TEXT)            {                if (isLoginfo)                {                    if (Util.isNull(parser.getText())) {                        regist.setUserId(parser.getText());                    }                 }                if (isName)                {                    if (Util.isNull(parser.getText())) {                        regist.setUsername(parser.getText());                    }                 }                if (isGender)                {                    if (Util.isNull(parser.getText())) {                        regist.setGender(parser.getText());                    }                }                if (isDepart)                {                    if (Util.isNull(parser.getText())) {                        regist.setDepart(parser.getText());                    }                }                if (isPass)                {                    if (Util.isNull(parser.getText())) {                        regist.setPass(parser.getText());                    }                }                if (isEmail)                {                    if (Util.isNull(parser.getText())) {                        regist.setEmail(parser.getText());                    }                }                if (isAge)                {                    if (Util.isNull(parser.getText())) {                        regist.setAge(parser.getText());                    }                }            }            else if (type == XmlPullParser.END_TAG                    && name.endsWith(regist.USERBEAN))            {                break;            }            type = parser.next();           }           }           }        }        }    } catch (XmlPullParserException e) {        UtilLog.e(""Xml XmlLogin-handleExtraElementInEntry(): ""                e.getMessage());    }}

}

应该是解析时出错了，可是都两天了，实在是找不到原因，只能求助于各位大神啦。

解决方案

我也遇到了这样的问题，但是是这样的，同事在SVN中修改了ServerHost，我这边没有更新完全报了这一个错误，修改后解决了
