What you learn:
You will learn how to properly parse XML
(here: from the net
) using a SAXParser
.
What it will look like:
Description:
0.)
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
URL
(
"http://www.
