In this tutorial we are going to parse the following XML-File located at the following url: http://www.anddev.org/images/tut/basic/parsingxml/example.xml
:
XML:
<?xml
version
="1.0"
?>
<outertag>
     <innertag
sampleattribute
="innertagAttribute"
>
          <mytag>
               anddev.org rulez =)
          </mytag>
          <tagwithnumber
thenumber
="1337"
/>
     </innertag>
</outertag>
To accomplish the parsing, we are going to use a SAX-Parser
(Wiki-Info
). SAX
stands for "S
imple A
PI for X
ML
", so it is perfect for us
1.)
Lets take a look at the onCreate(...)
-method. It will open an URL
, create a SAXParser
, add a ContentHandler
to it, parse the URL
and display the Results
in a TextView
.
Java:
     /** Called when the activity is first created. */
     @Override
     public
void
onCreate(
Bundle icicle)
{
          super
.onCreate
(
icicle)
;
          /* Create a new TextView to display the parsingresult later. */
          TextView tv = new
TextView(
this
)
;
          try
{
               /* Create a URL we want to load some xml-data from. */
               URL
url = new
