Regular Expressions + using them in Vector analysis

I would be very glad for any hint concerning this problem:
Consider this ilustrational code sample
import java.util.regex.*;
Vector sequence = new Vector();
        sequence.add("B");I want to find the first occurence of any alphabetical character ...I thought I can do it like this:
int index = sequence.indexOf("\\w");or from the other point of view like this:
int index = sequence.indexOf("[^-]");Unfortunately none of these are working. Do you know why and how to fix this? There are supposed to be only alphabetical characters and "-" character...
thanks a lot

well, the code I posted above should suit only as an illustration of my problem.
ActualIy I have a bunch of those sequences in an can be from 5 - 100 sequences(vectors) and I need to use some methods which are available only for Collections (frequency(), insertElementAt()...etc.). I am not a proffesional programmer so I do hope that I am using it correctly instead of "simple" String[][] BunchOfSequences = {seq1,seq2,...}I am not aware of any frequency() or insertElementAt() methods in one of Java's collection classes.
Is it possible to use regular expressions to find a first occurence of a "a-z"(or "A-Z" doesnt matter) in a vector then? Or I just need to find it in a "for loop"?
adamRegexes only work on Strings, not on collections holding Strings. So yes, you will need to use a for statement (or similar).
List<String> list = ...
for(String s : list) {
  if(s.matches("\\w")) {

  • How to define a regular expression using  regular expressions

    I am looking for some regular expression pattern which will identify a regular expression.
    Also, is it possible to know how does the compile method of Pattern class in java.util.regex package work when it is given a String containing a regex. ie. is there any mechanism to validate regular expression using regular expression pattern.

  • Regulare Expressions - Uses of logical operators

    I need to make use of logical operators within a regulare expression. (greater than, equal, etc.)
    It seems to me that java.util.regex.Pattern does not support that kind of expression. First of all: Is this true (If I am wrong with my assumption, how would the expression look like). Secondly: Which library does support this expression?
    Thanks in advance!

    Regular expressions deal with characters. In that context all characters are 'equal'. You better explain your question a helluva lot better than that.

  • Regular expression: using replaceAll

    I have the following input text:
    hello javascript:link('1') bye
    hello javascript:link('2') bye
    hello javascript:link('2') bye
    javascript:link('3') hello javascript:link('2')
    I am using the folllowing regular expression:
    in the following code:
    File file = new File("C://simple.txt");
    String regex = "javascript:link(\\(.*?\\))";
    String replacement = "REPLACED";
    String output = "";
              BufferedReader input;
              try {
              input = new BufferedReader(new FileReader(file));
                   String text = input.readLine();
                   while(text != null) {             
              Pattern pattern = Pattern.compile(regex);
              Matcher matcher = pattern.matcher(text);
              if(matcher.find()) {
              output = matcher.replaceAll( + replacement);
                   text = input.readLine();               
              catch (Exception e) {
    And my output is:
    hello ('1')REPLACED bye
    hello ('2')REPLACED bye
    hello ('2')REPLACED bye
    ('3')REPLACED hello ('3')REPLACED
    Firstly, why do the brackets appear in ('1'). I would expect '1'
    Secondly, how do I get the output to say ('3')REPLACED hello ('2')REPLACED, instead of ('3')REPLACED hello ('3')REPLACED

    The examples I gave work with what you have suggested.
    I now need to take it a step further. This is my code now:
    String test = "javascript:link('3X') hello javascript:link('2') hello javascript:link('3X')";
    String pattern = "javascript:link\\('(.*?)X'\\)";
    System.out.println(test.replaceAll(pattern, "$1:REPLACED"));
    But the output is:
    3:REPLACED hello 2') hello javascript:link('3:REPLACED
    I would like the output to be:
    3:REPLACED hello javascript:link('2') 3:REPLACED
    How can I achieve this?

  • DOM Parser fails with regular expression using anchor (carat, dollar)

    I'm using version "Oracle XDK Java Production"
    In trying to parse XML against schema: a regular expression fails to parse the data "8:00" with the following simple regular expression: "^.*$" (used to narrow the error)
    The error message is
    <Line 14, Column 25>: XSD-2025: (Error) Invalid text '8:00' in element: 'XYZ'
    If I remove the anchors and just have ".*", the data is parsed successfully.
    I dont understand why the parse fails when I use a anchors in the regular expression, and the java Pattern/Matcher classes succeed with the anchors?

    That "ns670" string is an xml namespace prefix. it should have a corresponding xml namespace declaration somewhere in the xml document (i'm guessing you have not shown the whole document). the actual value of an xml namespace prefix is meaningless. if you parse the xml with a namespace aware DOM parser, it should generate Nodes with the correct namespace. the namespace is the value you care about when extracting data from the document, not the namespace prefix.
    alternately, if you parse the document using a namespace aware DOM parser, you can just look for nodes based on their "local" name (the part after the ":" separator) and ignore the namespace/prefix.
    whatever you do, please do not parse the xml with a regex, see this for details (applies to xml as well).

  • Regular expressions, using pattern and matcher but not include the pattern

    Hi all
    i have a regular expression but in my matcher it is including the text that is in my regular expression.
    String str="-------------------stuff===========";
    Pattern mainBody = Pattern.compile("-----(.*?)=====", Pattern.MULTILINE);this matches -------------------stuff=====
    now i expect to get some - in there as i match from the start, but i dont want to have the = in the match. how do i do a match that excludes the matching expressions.

    nevermind, figured it out
    when i do it gives me just my match
    sorry for wasting time :)

  • Regular expressions using jsp

    Hello Techies,
    I am having a text area inside a jsp file. When ever the end user gives input it must be submitted to the server.
    The real problem is when the end user gives special characters and double-quotes in this text area, jsp is preforming in abnormal way.
    Can u guys tell me how to resolve this issue. i.e how to solve regular expressions in jsp.
    Even though the end user gives special characters or double quotes we should take only the content.
    Looking forward for u reply.

    The real problem is when the end user gives special characters and double-quotes in this text area, jsp is preforming in abnormal way.What do you mean with "jsp is preforming in abnormal way" ?
    A arbitrary JSP does not care about double-quotes.
    Can u guys tell me how to resolve this issue. i.e how to solve regular expressions in jsp.Usually the same way as you do it in a poj class.
    Nobody here knows how your JSP looks like and who handles the request when the form is submited or even who generates the model of the data displayed by your JSP.
    You have to provide us with more details.

  • How to use regular expression using pattern and match concept for this scenario?

    Hi Guys,
    I have a string "We have 7 tutorials for Java, 2 tutorials for Javascript and 1 tutorial for Oracle"
    I need to replace the numbers based on the below condition.
    if more then 5, replace with many
    if less then 5, replace with a few
    if it is 1, replace with "only one"
    below is my code, I am missing the equating part to replace the numbers could any one of you please help me out fixing this.
    private static String REGEX="(\\d+)";
      private static String INPUT="We have 7 tutorials for Java, 2 tutorials for Javascript and 1 tutorial for Oracle";
      //String pattern= "(.*)(\\d+)(.*)";
      private static String REPLACE = "replace with many";
      public static void main(String[] args) {
      // Create a Pattern object
           Pattern r = Pattern.compile(REGEX);
        // Now create matcher object.
           Matcher m = r.matcher(INPUT);
           //replace the value 7 by the replace string
    //How to equate the (\\d+)  greater than a number  and use it the below code.
                  INPUT = m.replaceAll(REPLACE);
           //Print the final Result;
    Thanks and Regards,

    Try the following which makes use of  "appendReplacement" instead with the "start" and "end" methods to locate and check the searched "regExp" string before dynamically setting the "replace" string:
    String regExp = "\\d+";
    String input = "We have 7 tutorials for Java, 2 tutorials for Javascript and 1 tutorial for Oracle";
    String replace;
    Pattern p = Pattern.compile(regExp);
    // get a matcher object
    Matcher m = p.matcher(input);
    StringBuffer sb = new StringBuffer();
    while (m.find()) {
       Integer x = Integer.valueOf(input.substring(m.start(), m.end()));
       replace = (x >= 5) ? "many" : (x == 1) ? "only one" : "few";
       m.appendReplacement(sb, replace);

  • Java regular expressions using enum

    i have created an enum called MONTHS and would like to include it in a pattern. Can somebody give me a hint on how to do that? Should i do it manually (by creating a string like [Jan,Feb...]) or is there a better way?

    It works by iterating the months and getting a string: months= "Jan|Feb|..." and then appending it to the pattern string. For example:
        public static String getMonthsShortStringList()
            String sList="";
            for (MONTH_SHORT c: MONTH_SHORT.values())
            String newS=sList.substring(0,sList.length()-1);       
            return newS;
    and  then...
    String months=DateConsts.getMonthsShortStringList(); //get a months disjunctive list
    Pattern pattern1=Pattern.compile("("+months+")");
    Matcher matcher1=pattern1.matcher((CharSequence)s);
    boolean found1=matcher1.find();Is there an alternative to this?

  • Regular expressions: the shorter the string, the longer the time to analyse

    Hello there !
    I've got a problem with regular expressions...
    I analyse those two strings with the same regular expression, searching for the "message" word.
    The first of them, which is much longer than the other one, is instantly analysed... but the second one takes about to one second !
    Do you see the problem ? (I do not, as you can guess...).
    I tried to put the same special characters in the two ones... but it still works slowly for the second one.
    This is instantly analysed:
    "Coucou----- Origin.a.l. .message -----From: clems= To: Cl�ment S=ent: Wednes=day, April 30, 2003 1:38 PMSubject: Fw: mail de test----- Original Message -----From: clemsTo: Cl�ment Sent: Wednesday, April 30, 2003 1:37 PMSubject: mail de testcoucou, ceci est un mail de t.e.s.t... !!!Clems.".matches("((.*\\W)*\\Q" + "message" + "\\E(\\W.*)*)")

    Pleaaase, help ;)

    Well in fact everything seems to work... there was another problem...
    My regular expression seems to be wrong and the code too...
    I apologize... sorry for the waste of time.
    See you later :) for my next wrong problem ! :))

  • Problem in creating a Regular Expression with gnu

    Hi All,
    iam trying to create a regular expression using gnu package api..
    i need to validate the browser's(MSIE) userAgent through my regular expression
    userAgent is like :First one ==> Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)
    i wrote an regular expression like this:
    Actaully this is validating my userAgent and returns true, my problem is, it is returning true if userAgent is having more words at the end after Windows NT 5.0 like Second One ==> Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0) Testing
    i want the regularExpression pattern to validate the First one and return true for it, and has to return false for the Second one..
    my code is:
    import gnu.regexp.*;
    import gnu.regexp.REException;
    public class TestRegexp
    public static boolean getUserAgentDetails(String userAgent)
         boolean isvalid = false;
         RE regexp = new RE("Mozilla.*(.*)\\s*(.*)compatible;\\s*MSIE(.*)\\s*(.*)([0-9]\\.[0-9])(.*);\\s*(.*)Windows(.*)\\s*NT(.*)\\s*5.0(.*)");
         isvalid = regexp.isMatch(userAgent);

         String userAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)";
         boolean regoutput = getUserAgentDetails(userAgent);
         System.out.println("***** regoutput is ****** " + regoutput);
    }please help me in solving this..
    Thanks in Advance..

    Ofcourse, i can do comparision with simple string matching..
    but problem is the userAgent that i want to support is for all the MSIE versions ranging from 5.0 onwards, so there will the version difference of IE like MSIE 6.0..! or MSIE 5.5 some thing like that..
    any ways i will try with StringTokenizer once..!
    seems that will do my work..

  • Regular expression does not work in IE

    I'm having a regular expression which should check the content of an inputText field: it should contain a number, a character and the size should be at least 6. It's working when I test it in FireFox but it always fails to succeed in IE:
                <af:validateRegExp pattern="^(?=.*[a-zA-Z])(?=.*[0-9])[a-zA-Z0-9]{6,24}$"
                                   noMatchMessageDetail="Does not match."/>
              </af:inputText>How comes it does not work in IE (6.0)?
    Thanks in advance,

    hi Koen
    The web page you refer to ...
    ... seems to be doing server side Java regular expressions (and as such will behave the same in both FF and IE).
    The af:validateRegExp component you want to use does client side evaluation of the regular expression, using scripting, hence the apparent difference between FF and IE.
    There is also this web page ...
    ... that seems to behave similar to the markup and scripting resulting from the af:validateRegExp component.
    Besides the value "2abcdef" there seem to be others that are accepted by IE for the regular expression "^(?=.*[a-zA-Z])(?=.*[0-9])[a-zA-Z0-9]{6,24}$", values like these:
    "a2abcdef", "a2abcde", "abcdef2abcde", "2a3cdef", "2a34567"
    Although these values are not accepted by IE (but are accepted in FF):
    "2abcde", "23bcdef"

  • Regular Expressions from C++ to Java

    Does anyone know if it is possible to use the same regular expressions used in C++ with in Java? Here it is a regular expression used in a C++ program:
    ^[[:digit:]]{4}$"I did a test, but it does not work. It always evaluate to false.

    Does anyone know if it is possible to use the same
    regular expressions used in C++ with in Java? C++ doesn't have regexes, so presumably you are using a library (and noting that might help.)

  • Back reference for regular expressions on "Search & Replace".

    Can't I reference a result from my Regular Expression used on "Search Clause" into my "Replace Clause"?
    What I'm doing is:
    Using JDev 10.1.3 DP,
    Search Menu -> Replace in Files...
    Select "Regular Expressions"
    Text: (A[0-9]*?_)(.)
    Replace with: $2 (reference to the second Parenthesis in the "Text" Field).
    For example, in Java, I would so something like this:
    "Dummy String".replaceAll("(D.*? )(S)", "$2");
    Are there any other ways that I can just Search something and Replace for nothing? I need a simple "Search and Delete", you know?
    If I don't do that and try to leave it blank, a warning comes up saying that the "Replace with" field cannot be blank.
    Any sugestions?

    Please, anyone?
    Will I really have to delete 1200 occurrences by hand???
