Extracting a value from a String
I am getting back a String from a function in this format:
Underlying><Code>KGF</Code></Underlying>
Please note that a string is being returned and not an XML.
I need to extract KGF or any other value from this.
The String may contain various <Code> like ABCDS or HSBC or BloomBerg.
Hence I cannot use substring because I cannot use substring(codeReturned,20,<Dont know last element>)
DO I need to use index of? Can anyone please guide?
Please note that a string is being returned and not an XML.
Please make the extra effort to write out words such as "you" . The extra keystrokes won't cost much in the way of time, and the enhanced clarity will be appreciated by those communicating on a forum with international readership.
Strip everything between the < and the >. Either in a loop (pusdo code):
remove = false;
for i = 0 to string.length
char = string.charAt( i )
if char == '<' remove = true;
if remove then string.remove( i );
if char == '>' remove = false
If you like you can also do this with something called a [url=http://en.wikipedia.org/wiki/Regular_expression]Regular Expression[/url].

Just because you are not getting an XML file, does not mean you are not getting XML. If that is a literal example of one of the Strings you are getting, then you are getting a String that contains XML, so you can parse it as if it were an XML file. Simply
DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document dom = db.parse(new ByteArrayInputStream(string.getBytes()));
And you have loaded the String into an XML Parser.
Of course, the other Option is regex.
A quick hack:
String string1 = string.replaceAll("^.*<Code>([^<]*)</Code>.*$", "\1");
if your Strings appear always like that you may use this code perhaps
String ss = "<Underlying><Code>KGF</Code></Underlying>";
int ret = 0;
String mean = "";
String kgf ="";
for(int i=0;i<ss.length()-1;i++)
{
if(ss.substring(i, i+1).equals(">") && !ss.substring(i, i+2).equals("><"))
{
ret = i;
}
}
mean = ss.substring(ret+1,ss.length());
System.out.println(mean);
f:
for(int k=0;k<mean.length();k++)
{
if(!mean.substring(k, k+1).equals("><"))
{
kgf=kgf+mean.substring(k, k+1);
}
else
{
break f;
}
}
kgf = "KGF"
