How to parse html ul li to array charsequence in android

I have a html view get from asset. But i want to parsing <ul><li>Category 1</li></ul> to be charsequence array, so I can put it into listview.

My HTML data:

<html>
<body>
<ul>
<li>Category 1</li>
<li>Category 2</li>
<li>Category 3</li>
<li>Category 4</li>
</ul>
</body>
</html>

I want to get result 

CharSequence[] myList={"Category 1","Category 2","Category 3","Category 4"};

a bit strange to use a local html asset as a datasource for a listview, but anyway..

To extract the contents of the tags into an charsequence array you could use something like this

List<String> tagValues = new ArrayList<String>();
final Matcher matcher = Pattern.compile("<li>(.+?)</li>").matcher(theStringWithTags);
while (matcher.find()) {
    tagValues.add(matcher.group(1));
}

CharSequence[] cs = tagValues.toArray(new CharSequence[tagValues.size()]);

Cheers, Marcus
