我在解析
XML时遇到了麻烦,我尝试了很多东西.
我有像这样的xml. <question id="1" text="Zodiac Sign" > <option id="1" >Aries</option> <option id="2" >Taurus</option> <option id="3" >Gemini</option> <option id="4" >Cancer</option> <option id="5" >Leo</option> <option id="6" >Virgo</option> <option id="7" >Libra</option> <option id="8" >Scarpio</option> <option id="9" >Sagitarius</option> <option id="10" >Capricorn</option> <option id="11" >Acqauarius</option> </question><question id="2" text="Home Town" > </question><question id="3" text="Current Locaion" > </question><question id="4" text="Nationality" ></question> <question id="5" text="Height" ></question> <question id="6" text="Build(optional)" > <option id="13" >Slim</option> <option id="14" >Athletic</option> <option id="15" >Few Pounds Extra</option> <option id="16" >Obese</option> </question><question id="7" text="Hair Color" > </question><question id="8" text="Color Of Eyes" > <option id="23" >Black</option> <option id="24" >Brown</option> <option id="25" >Blue</option> </question><question id="9" text="Smoking Habits" > </question> 我需要得到问题,我想将它们保存在一个数组中,然后有一些问题有选项作为子标记,我想在另一个数组中添加这些选项,并引用该问题ID. 我怎样才能真正解析这个xml. 我一直在尝试使用XMLPullParser 这是我的代码,但它不起作用. StringBuilder sb = new StringBuilder();
int depth = 1;
while (depth != 0) {
switch (parser.next()) {
case XmlPullParser.END_TAG:
depth--;
if (depth > 0) {
sb.append("</" + parser.getName() + ">");
}
break;
case XmlPullParser.START_TAG:
depth++;
StringBuilder attrs = new StringBuilder();
for (int i = 0; i < parser.getAttributeCount(); i++) {
attrs.append(parser.getAttributeName(i) + "=""
+ parser.getAttributeValue(i) + "" ");
}
sb.append("<" + parser.getName() + " " + attrs.toString() + ">");
break;
default:
sb.append(parser.getText());
break;
}
}
payload = sb.toString();
解决方法
我已经构建了自己的解析器来解析这个xml.
这是代码 public class ProfileHome extends Activity {
public String id="";
public String text="";
public ArrayList<String>option = new ArrayList<String>();
public String singleoption="";
List<Questions> q;
private Questions question = new Questions();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.profile_home);
String payload = "<question id="1" text="Zodiac Sign" ><option id="1" >Aries</option><option id="2" >Taurus</option><option id="3" >Gemini</option><option id="4" >Cancer</option><option id="5" >Leo</option><option id="6" >Virgo</option><option id="7" >Libra</option><option id="8" >Scarpio</option><option id="9" >Sagitarius</option><option id="10" >Capricorn</option><option id="11" >Acqauarius</option></question><question id="2" text="Home Town" ></question><question id="3" text="Current Locaion" ></question><question id="4" text="Nationality" ></question><question id="5" text="Height" ></question><question id="6" text="Build(optional)" ><option id="13" >Slim</option><option id="14" >Athletic</option><option id="15" >Few Pounds Extra</option><option id="16" >Obese</option></question><question id="7" text="Hair Color" ></question><question id="8" text="Color Of Eyes" ><option id="23" >Black</option><option id="24" >Brown</option><option id="25" >Blue</option></question><question id="9" text="Smoking Habits" ></question>";
q = new ArrayList<Questions>();
if(payload.contains("question"))
{
for(int i=0;i<payload.length();i++)
{
Questions ques = new Questions();
// check if question has come
if(payload.substring(i,i+8).equals("question"))
{
i=i+9;
// check for the id,text and options
for(int k=i;k<payload.length();k++)
{
if(payload.substring(k,k+9).equals("/question"))
{
q.add(ques);
k=k+9;
break;
}else if(payload.substring(k,k+4).equals("id=""))
{
//get id
for(int j=k+4;j<payload.length();j++)
{
if(payload.substring(j,j+1).equals("""))
{
ques.setId(id);
id="";
k=j+1;
break;
}else
{
id= id + payload.substring(j,j+1);
}
}
//check for text
}else if(payload.substring(k,k+6).equals("text=""))
{
for(int j=k+6;j<payload.length();j++)
{
if(payload.substring(j,j+1).equals("""))
{
ques.setText(text);
id="";
k=j+1;
text="";
break;
}else
{
text= text + payload.substring(j,j+1);
}
}
//check for options
}else if(payload.substring(k,k+11).equals("option id=""))
{
for(int l=k;l<payload.length();l++)
{
if(payload.substring(k,k+11).equals("</question>"))
{
ques.setOptions(option);
q.add(ques);
k=k+11;
break;
}
//now get all options and their id's
for(int j=k+11;j<payload.length();j++)
{
//get id and text
if(payload.substring(j,j+9).equals("</option>"))
{
option.add(singleoption);
singleoption="";
k=j+9;
break;
}else{
singleoption = singleoption +payload.substring(j,j+1);
}
}
}
}
}
}
}
}
for(int i=0;i<q.size();i++)
{
q.get(i).getText();
q.get(i).getId();
q.get(i).getOptions().toString();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.profile_home,menu);
return true;
}
}
