I do it this way (it works for me):
/**
* @param tag The tag without the angle bracket, i.e.,
* the given value does not start with "<".
* @param str The string containing the tags and data.
* @return empty string when tag absent or str invalid.
*/
String takeit(String tag,String str){
try{
int i = str.indexOf("<"+tag+">");
if(i<0){
i = str.indexOf("<"+tag+" ");
}
if(i<0) {
return "";//tag not found
}
String s = str.substring(i);
i = s.indexOf(">");
if(i<0) {
//no matching end-angle-bracket (>)
return "";
}
s = s.substring(i+1);//the returned string begins with the data
of this tag
int j = s.indexOf("</"+tag+">"); //in this version, "<tag/>"
tags are not used.
if(j<0) {
//TODO Log.d(...)
return "";
}
s = s.substring(0,j); // j is the position of the end-tag.
return s.trim();
}catch(Exception ex){
/* TODO maybe
Log.d("myClass",ex+" - Thread.currentThread()
+".takeit() returning empty string;"
+" tag = "+tag
+"; str = "+str
);
*/
return "";
}
}
