src\b4a\example\main.java:379: error: inconvertible types
_text = (String[])(anywheresoftware.b4a.keywords.Common.Regex.Matcher("<description>(.*)</description>",mostCurrent._reciver._getstring()).getObject());
                  ^
  required: String[]
  found:    Matcher

Answer 1

As the error message says, Regex.Matcher returns an object of type Matcher , but your variable text expects a String[] . You need to extract the strings from the matcher, so you can put them into text .

From the B4A docs , you would need to do something like this:

Dim Matcher1 As Matcher
Matcher1 = Regex.Matcher("<description>(.*)</description>", reciver.GetString)
Do While Matcher1.Find
    ListView1.AddSingleLine(Matcher1.Match)
Loop

This would still match <description> and </description> though. Using regex is not the best option in this case, a proper XML parsing library would probably be better.
