How to parse xml file using XMLReader
提问by Aditya Mehta
I have a "contacts.xml" file, its structure is:
我有一个“contacts.xml”文件，它的结构是：
<?xml version="1.0" encoding="UTF-8"?>
<Contacts>
<Contact>
<ContactId>1</ContactId>
<ContactName>Aditya Kothari</ContactName>
<MobilePhone1>NA</MobilePhone1>
<MobilePhone2>NA</MobilePhone2>
<OfficePhone1>NA</OfficePhone1>
<OfficePhone2>NA</OfficePhone2>
<OfficePhone3>NA</OfficePhone3>
<HomePhone1>999-367-3944</HomePhone1>
<HomePhone2>NA</HomePhone2>
<TokenId>mtn</TokenId>
</Contact>
<Contact>
<ContactId>2</ContactId>
<ContactName>Jai Mandloi </ContactName>
<MobilePhone1>NA</MobilePhone1>
<MobilePhone2>NA</MobilePhone2>
<OfficePhone1>NA</OfficePhone1>
<OfficePhone2>NA</OfficePhone2>
<OfficePhone3>NA</OfficePhone3>
<HomePhone1>800-742-9678</HomePhone1>
<HomePhone2>NA</HomePhone2>
<TokenId>mtn</TokenId>
</Contact>
</Contacts>
Now i am doing this-
现在我正在这样做-
File xmlFile = new File("E:\contacts.xml");
InputStream is = new FileInputStream(xmlFile);
XMLInputFactory factory = XMLInputFactory.newInstance();
XMLStreamReader reader = factory.createXMLStreamReader(is);
while(reader.hasNext())
{
if(reader.hasText()
{
System.out.println(reader.getText());
}
reader.next();
}
I do not want values of "ContactId" and "TokenId" elements of xml. How should i code?
我不想要 xml 的“ContactId”和“TokenId”元素的值。我应该如何编码？

Recently i got this way-
最近我得到了这种方式-
while(reader.hasNext())
{
if(reader.getEventType()==XMLStreamConstants.START_ELEMENT)
{
if(!reader.getLocalName().equals("ContactId") && !reader.getLocalName().equals("TokenId") && !reader.getLocalName().equals("Contacts") && !reader.getLocalName().equals("Contact"))
{
System.out.println(reader.getElementText());
}
}
reader.next();
}
