RegEx library question

[Mario Barón]

Hey guys,

I have a question about the regEx library, I'm really just a beginner with reguar expressions but I've been trying to write one that helps me evaluate when the user writes a home address which should be in this format (for example):

Street 3 # 6 - 4

it should check if the user wrote something from the # character onwards including the #. I have tested this expression /(?:# *).+/gi in some online testers like this one and it seems to do the trick. But when I run it through the regEx library it always returns false as if no matches were found. 

This is my code by the way:

 public static boolean validateRegEx(String pattern, String source) {

    RE r = new RE(pattern);

    if (r.match(source)) {

      return true;

    } else {

      return false;

    }

  }

Is there something wrong with the expression, or is there something I'm not doing right with the library? Really appreciate your help.

Thanks.

Can you post the part of the code where you specify the regex string.  Make sure not to include the slashes at the beginning and end .

Hey Steve,

thanks for the extremley fast response =) here is the full code:

  public static final String DIRECTION_PATTERN = "/(?:# *).+/gi";
  String direction = "Carrera 32 # 49-44";

 boolean isDirectionComplete = Utilities.validateRegEx(Utilities.DIRECTION_PATTERN, direction);

[Mario Barón]

Sorry, accidentally published that incomplete. I have tried with 

direction = "Carrera 32";

also and it still says it doesn't match.

Regex strings should be java-style regex strings.  You don't include the '/' at the beginning and end.  And your "gi" flags should be specified using the match flags in the second parameter.

These javadocs should be helpful.

http://regexp-me.googlecode.com/svn/trunk/regexp-me/doc/me/regexp/RE.html

So your regex would be something like:

RE re = new RE("(?:# *).+", RE.MATCH_CASEINDEPENDENT);

Hey Steve, 

sorry for bothering you again, but I'm testing this regular expression and it only seems to validate the address as incomplete when it doesn't contain blank spaces after the # character. Do you know how I can modify it to take this case into consideration? I was sure the * after the space included this case but as I said previously, I'm not that experienced with regular expressions

For example:

address= "Carrera 23"   ==> incomplete

address= "Carrera 23 #"   ==> incomplete

address= "Carrera 23 # "   ==> incomplete

address= "Carrera 23 #         "   ==> incomplete

address= "Carrera 23 # 31a"   ==> complete

address= "Carrera 23 #31a"   ==> complete

Thanks a million.

If you want to just match the # to the end of the input, you could just to

RE re = new RE("#.*$", RE.MATCH_CASEINDEPENDENT);
