pull 方式解析xml文件

1. XmlPullParser解析xml的android文档docs/reference/org/xmlpull/v1/XmlPullParser.html

2. xmlPullParer官网:http://www.xmlpull.org/

   例子:要解析的文件:pull.xml

3. <?xmlversion="1.0"encoding="UTF-8"?>
   <Customer>
   <PersonName>
   <SurName>张三</SurName>
   </PersonName>
   <PersonName>
   <SurName>李四</SurName>
   </PersonName>
   
   <ContactNamecontactType="CSM">
   <PersonName>
   <SurName>王五</SurName>
   </PersonName>
   <TelephonePhoneTechType="Mobile"PhoneNumber="1310000000"/>
   <Email/>
   </ContactName>
   </Customer>

   解析此文件的java文件:

   Stringtag=xmlParser.getName();
   Log.d(TAG,"tag="+tag);
   if(tag.equalsIgnoreCase("Customer"))
   {
   customers=newArrayList<Customer>();
   }
   elseif(tag.equalsIgnoreCase("PersonName")&&personCount<2)
   {

   personCount++;
   }
   elseif(tag.equalsIgnoreCase("ContactName"))
   {

   customer.mContactType=xmlParser.getAttributeValue(null,"contactType");
   }

   }
   break;
   caseXmlPullParser.END_TAG:

   {
   customers.add(customer);
   if(personCount<2)
   {
   customer=null;
   }
   }
   elseif(xmlParser.getName().equalsIgnoreCase("SurName"))
   {
   customer.mSurName=buffer.toString().trim();
   }
   break;
   caseXmlPullParser.TEXT:
   Log.d(TAG,"text="+xmlParser.getText());
   buffer.append(xmlParser.getText());
   break;
   default:
   break;
   
   }
   evtType=xmlParser.next();
   }
   
   }catch(Exceptione){
   //TODO:handleexception
   e.printStackTrace();
   }
   returncustomers;
   }
   
   }

   customer.java

5. packagecom.xmlpullparser;
   publicclassCustomer
   {
   publicStringmSurName;
   publicStringmContactType;
   publicStringmPhoneTechType;
   publicStringmPhoneNumber;
   }
