Parse an XML into Java - MetaData Format

Question

I saw some xml parsing in java but I really don't know how I can apply it to my code.

Here is my xml file:

<?xml version="1.0" encoding="UTF-8"?>
<entry xmlns="http://www.w3.org/2005/Atom" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:georss="http://www.georss.org/georss" xmlns:gml="http://www.opengis.net/gml" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xml:base="https://adomain.com">
   <id>https://sharepoint.mydomain/aFile)</id>
   <category term="SP.File" scheme="http://schemas.microsoft.com/ado/2007/08/dataservices/scheme" />

         <d:UIVersion m:type="Edm.Int32">1</d:UIVersion>
         <d:UIVersionLabel>0.1</d:UIVersionLabel>
      </m:properties>
   </content>
</entry>

I am trying to get the metadata of a file from SharePoint which is displayed in xml format.

How can I get the data which is inside the content and also the title and the author like this:

Author BlaBla
Title Bla
Type application/xml
TimeLastModified xx/xx/xxxx

Answer 1

You can use Jaxb, now a days it is used for parsing purpose very effectively, Converting XML to JAVA called UnMarshalling http://www.javatpoint.com/jaxb-tutorial

Answer 2

The easiest way to parse XML files is the DOM parser. You can find the documentation here and a few tutorials here and here.
