I need to search in a line a string but...

Question

Hi there!, I hope you can help me with my problem...
I have a line from an html file like this:
String lineToSearch = "<b>This is a line with a different font<b>"
Well, I have a method that searchs a word or a character in the variable lineToSearch, and it works fine, but it doesn't know to differentiate between a normal character and the tags of an html file, if I want to search the word "font" in the variable lineToSearch, works good, but if the variable have a different line like this:
lineToSearch = "<font color = yellow>This is a line with a different font</font>"
find three time the word, how can I avoid the tags???

Ok the logic is to try to indentify in your string the <bla bla > statements and process only the value...one way (prob my implementation is not very nice but works ok for now
in a string like that :
"<font color = yellow>This is a line with a different font</font>"
we can identify 2 <bla bla> substrings and the value substring
The thing we want is the string between the > and the < right?
This is a line with a different font<So the logic of the code is convert string to char[] array .search the indexes of the < and > characters
in a string like that < blabla > adfasdfasdf </blabla> searching for < and > will give as 4 indexes
so using the indexes of the first > and the second < as they appear in the string we give as the value only...after that you can call your method to process the string
public String giveSubString(String s) {
s="<font color = yellow>This is a line with a different font</font>";
char[]r=s.toCharArray();
Vector indexes= new Vector();
for(int x=0;x<r.length;x++)
if(r[x]=='<'||r[x]=='>')
indexes.add(new Integer(x));
String s1 = s.substring(((Integer)(indexes.get(1))).intValue()+1,((Integer)(indexes.get(2))).intValue());
System.out.println(s1);
return s1;
This logic wont work for a string like that <bla><c>sadfsadfasdf</c></bla> but you can easily modify the logic with the indexes
I hope it helped...if your need further assistance dont hesitate to email me ..because I cant visit the forum so often
