String HTML char from text field??
So here is my issue. I have some text fields that can store HTML formatted data in SFDC. For example "<strong>Test</strong>". What I need to do is get a character count of the non HTML characters in that field. So for our example I want to know that there is 5 char in it not 22 char.
I can do this in Javascript by using a regular expression:
var re= /<\S[^>]*>/g; var test = "<strong>Test</strong> test = test .replace(re,"");
But I woudl like to do it in APEX and store the char count in a field on that record. I am not Java guy so all the examples seem to drive me to have a beer. Can anyone point me in the right direction? All I really need to know how to do is perform the above Javascript code in APEX...and I think I need to user the "replaceAll" method.
Thanks in advance!

Public Static String getEmailFromSubjecct(String Subject){
// First, instantiate a new Pattern object "MyPattern"
String emailRegex = '(\\w+)@(\\w+\\.)(\\w+)(\\.\\w+)*';
Pattern MyPattern = Pattern.compile(emailRegex);
// Then instantiate a new Matcher object "MyMatcher"
Matcher MyMatcher = MyPattern.matcher(Subject);
boolean hasMatch = MyMatcher.matches();
String match = MyMatcher.group(0);
return match;
}
I exactly can't guess what your purpose is. However I believe that following code will give you an idea.
If this is not what you are looking for, please supply more info and then I can help you.
public with sharing class LengthCounter{
public Integer getLength() {
Integer charCount = 0;
Pattern pat = Pattern.compile('<[^>]*>([^><]*)<.*');
Matcher matcherInstance = pat.Matcher('<strong>Test</strong>');
if (matcherInstance.find()) {
charCount = matcherInstance.group(1).length();
}
return charCount;
}
}
