Use a regular expression to do this...

I need to process this line : "STRTsomeEND.STRTsome2END.STRTsome3END"
to get an array with this values :
String[] processedLine = {
{"STRTsomeEND."}
{"STRTsome2END."}
{"STRTsome3END."}
I tried to use this regular expression to do the work: (STRT[.*]END.)+ but doesn't work. Also I tried with this expresion STRT[.*]END. But I only got the first ocurrence ("STRTsomeEND") .
Can anybody help me?

when you ask a question and then someone gives you advice you should
give them the benefit of the doubt (for at least a little while).
did you take a moment to try to understand what i was saying about escaping the "."?
anyway, your regex should be:
(START)(.*?)(END)\ \ .
the "?" after the "\*" means "reluctant". you dont want the ".\*" to grab up everything.
with the reluctant modifier "?" the regex should stop and grab the first available "END".
and finally, if you meant the "." at the end of "STARTsomethingEND." literally then:
you need to escape the "."

Track the entered answer using the Regular expression

Hi,
I am building a Q&A application which does have user to answer descriptive answer for the question(Text based answer rather than objective)
in this case how we can track the entered answer by the user is the correct one? how we can capture the entered answer and then check with the correct
answer in the DB? Yes we need to use a regular expression , but how we know that entered one is matching with the one in the DB
as the user can answer in lengthy or short form ? Hence please clarify how we can proceed?
Thanks.

How to use regular expression replace for this special characters?

hi,
I need to replace the below string, but i couldnt able to do if we use the special charaters '+', '$' . can anyone suggest a way to do this?
select REGEXP_REPLACE('jan + feb 2008','jan + feb 2008', 'feb',1,0,'i') from dual
anwers should be :- feb

you should use escape character \.
the regular expression will look like as follows:
select REGEXP_REPLACE('jan + feb 2008','jan \+ feb 2008', 'feb',1,0,'i') from dual
hope this is what you needed.
cheers,
Davide

IR filter using "matches regular expression"

Hi,
I am familiar with Perl regular expressions, but I'm having trouble using the IR filter by regular expression in Apex.
For instance, I would like to search for dates of format 'MM/DD/YY' - can someone tell me how this would be done? I tried '[0-9](2)/[0-9](2)/[0-9](2)' and many other patterns to no avail.
Also can you point me to a good thread for regular expressions in Apex?
Thanks for any help.

Hi,
you can play around with oracle regular expressions at
http://www.yocoya.com/apex/f?p=YOCOYA:REGEXP_HOME:0:
It's an Apex application, albeit "seasoned", where you can build and test the regex and it will be 100% compatible as it runs natively, so it's not simulated on a different platform.
Most likely the IR filter will make use of REGEXP_LIKE so you can pick that function from the menu.

How about the statement of regular expression like for this

I what to get varians String array by one regular express for the statement like:
${user} like play ${game} in ${date}
I want to get String[] as {"user","game","date"} by one regex, by str.split(regex). I tried many times but always fail to get the result I expected. May it be possible to meet the destination?
thanks in advance

why StringBuffer was using here?So one could split the pattern into multiple lines. But it just occurred to me that one could just use string concatenation, which would look better. I don't know why I bothered to use StringBuffefer.
e.g.:
String pattern =
    "^" +           // the start of a string
    "(dog)|(cat)" + // match either "dog" or "cat" at the start of the line
    "\\s*" +        // match an arbitrary amount of whitespace
    "$";            // but don't allow anything other than whitespace after dog or cat
Pattern p = Pattern.compile(pattern);
Pattern p = Pattern.compile("^(dog)|(cat)\\s*$");> isn't this look more simpler and better?
In this case, yes. I was looking for a way to make regexps more explicit, with whitespace and comments, for more complicated cases.
But those double quotes and plus signs add ugliness of their own, so a regexp would have to be pretty complex before it would be an improvement.

How can I use regular expression to match this rule

I have a String ,value is "<a>1</a><a>2</a><a>3</a>",and want to match other String like "<a>1</a><a>8</a>",if the one of the first string(like "<a>1</a>") will occur in the second string,then will return true.but I don't know how to write the regular expresstion.
Thx

Fine fine. :P
I was a little bored, so here's some code that uses Strings and a StringBuffer (though you could use a String in place of the StringBuffer). Is this perhaps better? :)
          String testMain = "<a>1</a><ab>2</ab><ab>3</ab>";
          String test = "<ab>1</ab><ab>3</ab>";
          String open = "<ab>";
          String close = "</ab>";
          StringBuffer search = new StringBuffer();
          String checkString = null;
          int lastCheck = 0;
          int start = 0;
          int finish = 0;
          boolean done = false;
          while (!done) {
               start = test.indexOf(open);
               finish = test.indexOf(close);
               if ((start == -1) || (finish == -1)) {
                    System.out.println("No more tags to search for.");
                    done = true;
               else {
                    checkString = test.substring((start + open.length()), finish);
                    search = new StringBuffer();
                    search.append(open);
                    search.append(checkString);
                    search.append(close);
                    if (testMain.indexOf(search.toString()) != -1) {
                         System.out.println("Found value: " + checkString);
                    test = test.substring(finish + close.length());
Resulting output:
Found value: 3
No more tags to search for.

Using a regular expression in String's split method

I have a String that is delimited by commas that I would like to split into a String array. However, the problem is that it is valid that some of the elements could have embeded commas in them. These "extra" commas are always in a predefined pattern though.
For example, the String that I want to parse may look like this (quotes omitted):
data with spaces and tabs , more data with more spaces, now for the problem(5,9), and now some more text and spaces
What I would like the result to be (shown below as if each element has been trimmed):
data with spaces and tabs
more data with more spaces
now for the problem(5,9)
and now some more text and spaces
string.split("[,&&[^[\$.,.\$]]]");The idea being that I want to split on all commas except those that are in the pattern (5,9). Where 5 and 9 could be any integer.
The above expression isn't working. It isn't ignoring the comma in the pattern.
Any suggestions?
Thanks.

i dunno if this help...
There is a class called the StringTokenizer class where it splits the String and delimiter up..e.g
String s1="Hello,Welcome,Can";
String[ ] arr=new String[3];
To use the StringTokenizer, you create.
StringTokenizer st=new StringTokenizer(s1,",");
//this will split the words, hello,welcome and can into "Tokens"
Then use this method .hasMoreTokens( )
int i=0
while(st.hasMoreTokens( ) ==true) {
arr=st.nextToken( );
i++;
Hope this helps! =)

Why am I both unable to open Firefox and unable to uninstall it? I used Firefox regularly until today, but this morning I did a System Restore and other troubleshooting and now Firefox is completely unavailable to me.

I've been having lots of problems with my computer abruptly shutting down lately. This problem '''''might''''' be solved -- it's too early to tell.
When I try to uninstall Firefox, it beeps like Windows is going to uninstall it, then nothing. I close out the Window, then search for it to see if it's gone. It's still there.
I like Firefox, but now I'm forced to use IE. How can I get Firefox back? I don't want to download it until I've uninstalled what's on here now.

First, please try reinstalling Firefox over your current installation. There is very little risk of making things any worse than the system restore function has already done.

Use of Regular Expressions in BI Query Designer

Hello All,
For a particular requirement in Inventory, I have the following to be achieved:
If at the input selection screen, if Plant entered is 'AB12', then it should show batches only startign with 'J' and if Plant entered is 'AB13' then the query output should show only batches with '$****K' (where * indicates any digit and $ indicates any character.
Will I be able to achieve this at query level, since my design for Inventory is already existing.
One way is I can always take it to a new cube and write some routines in transformation to achieve the same, but that would in essence duplicate data at multiple places.
Request to guide me for the same.
Thank you.
Regards,
Kunal Gandhi

Hi,
If you are able, create a Structure in your Query and add 2 Selections to it.
Restrict 1 Selection on Plant AB12, and Batch J****** using Contains Pattern as described by Mansi. Restrict the other Selection on Plant AB13, and Batch $*****K again using Contains Pattern.
Activate Zero Suppression on this Structure.
When the user selects a Plant in the input, only the Selection which contains that Plant will be displayed.
Hope this helps. Sorry it is so long after the question, I found this while looking for something else.

$10 for answer: using Pattern - regular expressions and Scanner

I'm trying to read input messages using Scanner. The messages are in format: word1 word2 number. the "number" is followed by "C null terminator" i.e. '\u0000' character.
I tried this:
Scanner input;
          Pattern pat = Pattern.compile("(\\w+) (\\w+) (\\d+)\u0000");
          input.useDelimiter(pat);
          while (input.hasNext(pat)) {
The input is there and in correct format, but it hangs hasNext(pat) - as if input is not correct. What did I do wrong? Thanks in advance - thsi is urgent, I'd be glad to send you $10 for correct answer via PayPal.

Here is a Regex and a Scanner implementation.
The price is $20 because there are 2 ways to do this.
Plus at least a $10 courtesy tip.
import java.util.Scanner;
import java.util.regex.*;
public class RegexTest{
public static void main(String[] args){
     new RegexTest();
public RegexTest(){
     String input = "word1 word1 1\u0000 word2 word2 2\u0000 word3 word3 3\u0000";
     Pattern pattern = Pattern.compile("(\\w+ \\w+ \\d+\\u0000)");
     Matcher matcher = pattern.matcher(input);
     while(matcher.find() == true){
     System.out.println("Match: " + matcher.group());
     String input = "word word 1\u0000 word2 word2 2\u0000 word3 word3 3\u0000";
     Pattern pattern = Pattern.compile("(\\w+) (\\w+) (\\d+)\\u0000\\s*");
    Scanner scanner = new Scanner(input);
     String result;
     while((result = scanner.findInLine(pattern)) != null){
     System.out.println("Match: " + result);
     System.out.println("Done.");
}Edit: Changed Pattern to end with \\s* to be insensitive to ending spaces

Without using a regular expressions in oracle 9i

dear all;
I have the following test data below
insert into p
      (id)
    values
      ('\G1\G2');
insert into p
      (id)
    values
      ('\A1\');
   insert into p

    values
      ('\B1\B2\B3');
       insert into p
      (id)
    values
      ('\J1\J2\J3\J4');and this is the output I desire though
ID
G1
null
B2
J3the output is gotten by looking at the second to the last entry and extracting it....
so for \G1\G2 the second to the last entry was G1 hence we have G1
for \A1\ there is no second to the last entry and that is why it is null
for \B1\B2\B3 the second to the last entry was B2

'\AI',
'\A1\' or
'\A1\\\\\\\\\\\\'
there's only entry in id, and so you want to return NULL. Is that right?
Here's one way to do that in Oracle 9:

     SELECT     id

                , 1)     AS pos_to
     FROM     p
SELECT       id
,       CASE
           WHEN pos_from     > 1
           THEN SUBSTR ( id

Re: [iPlanet-JATO] Re: Use Of models in utility classes - Pease don't forget about the regular expression potential

Namburi,
When you said you used the Reg Exp tool, did you use it only as
preconfigured by the iMT migrate application wizard?
Because the default configuration of the regular expression tool will only
target the files in your ND project directories. If you wish to target
classes outside of the normal directory scope, you have to either modify the
"Source Directory" property OR create another instance of the regular
expression tool. See the "Tool" menu in the iMT to create additional tool
instances which can each be configured to target different sets of files
using different sets of rules.
Usually, I utilize 3 different sets of rules files on a given migration:
spider2jato.xml
these are the generic conversion rules (but includes the optimized rules for
ViewBean and Model based code, i.e. these rules do not utilize the
RequestManager since it is not needed for code running inside the ViewBean
or Model classes)
I run these rules against all files.
See the file download section of this forum for periodic updates to these
rules.
nonProjectFileRules.xml
these include rules that add the necessary
RequestManager.getRequestContext(). etc prefixes to many of the common
calls.
I run these rules against user module and any other classes that do not are
not ModuleServlet, ContainerView, or Model classes.
appXRules.xml
these rules include application specific changes that I discover while
working on the project. A common thing here is changing import statements
(since the migration tool moves ND project code into different jato
packaging structure, you sometime need to adjust imports in non-project
classes that previously imported ND project specific packages)
So you see, you are not limited to one set of rules at all. Just be careful
to keep track of your backups (the regexp tool provides several options in
its Expert Properties related to back up strategies).

This is a great input for our migration. Though we used the existing

own needs as mentioned by Mike.
We would certainly incorporate this to ease our migration.

Great response. By the way, the Regular Expression Tool uses thePerl5 RE
syntax as implemented by Apache OROMatcher. If you're doing lotsof these
sorts of migration changes manually, you should definitely buy theO'Reilly
book "Mastering Regular Expressions" and generate some rules toautomate the
conversion. Although they are definitely confusing at first,regular
expressions are fairly easy to understand with some documentation,and are
superbly effective at tackling this kind of migration task.

Also, (and Matt's document may mention this)
Please bear in mind that this statement is not totally correct:
Since the migration tool does not do much of conversion for
these
utilities we have to do manually.Remember, the iMT is a SUITE of tools. There is the extractiontool, and
the translation tool, and the regular expression tool, and severalother
smaller tools (like the jar and compilation tools). It is correctto state
that the extraction and translation tools only significantlyconvert the
primary ND project objects (the pages, the data objects, and theproject
classes). The extraction and translation tools do minimumtranslation of the
User Module objects (i.e. they repackage the user module classes inthe new
jato module packages). It is correct that for all other utilityclasses
which are not formally part of the ND project, the extraction and
translation tools do not perform any migration.
However, the regular expression tool can "migrate" any arbitrary
file
(utility classes etc) to the degree that the regular expressionrules
correlate to the code present in the arbitrary file. So first andforemost,
if you have alot of spider code in your non-project classes youshould
consider using the regular expression tool and if warranted adding
additional rules to reduce the amount of manual adjustments thatneed to be
made. I can stress this enough. We can even help you write theregular
expression rules if you simply identify the code pattern you wish to
convert. Just because there is not already a regular expressionrule to
match your need does not mean it can't be written. We have notnearly
exhausted the possibilities.
For example if you say, we need to convert
CSpider.getDataObject("X");
To
RequestManager.getRequestContext().getModelManager().getModel(XModel.class);
Maybe we or somebody else in the list can help write that regularexpression if it has not already been written. For instance in thelast
updated spider2jato.xml file there is already aCSpider.getCommonPage("X")
rule:

<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[CSpider[.\s]*getPage[\s]*\(\"([^"]*)\"]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[CSpider[.\s]*getPage[\s]*\(\"([^"]*)\"]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[getViewBean($1ViewBean.class]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
Following this example a getDataObject to getModel would look
like this:
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[CSpider[.\s]*getDataObject[\s]*\(\"([^"]*)\"]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[CSpider[.\s]*getDataObject[\s]*\(\"([^"]*)\"]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[getModel($1Model.class]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
In fact, one migration developer already wrote that rule andsubmitted it
for inclusion in the basic set. I will post another upgrade to thebasic
regular expression rule set, look for a "file uploaded" posting.Also,
please consider contributing any additional generic rules that youhave
written for inclusion in the basic set.
Please not, that in some cases (Utility classes in particular)
the rule
application may be more effective as TWO sequention rules ratherthan one
monolithic rule. Again using the example above, it will convert
CSpider.getDataObject("Foo");
To
getModel(FooModel.class);
Now that is the most effective conversion for that code if that
code is in
a page or data object class file. But if that code is in a Utilityclass you
really want:
>
RequestManager.getRequestContext().getModelManager().getModel(FooModel.class
So to go from
getModel(FooModel.class);
To
RequestManager.getRequestContext().getModelManager().getModel(FooModel.class
You would apply a second rule AND you would ONLY run this rule
against
your utility classes so that you would not otherwise affect yourViewBean
and Model classes which are completely fine with the simplegetModel call.
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[getModel$]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[getModel\(]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[RequestManager.getRequestContext().getModelManager().getModel(]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
A similer rule can be applied to getSession and other CSpider APIcalls.
For instance here is the rule for converting getSession calls toleverage
the RequestManager.
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[getSession\($\.]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[getSession\.]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[RequestManager.getSession().]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>

Hi All,
In the present ND project we have lots of utility classes.
These

In these classes we access the dataobjects and do themanipulations.
So we access dataobjects directly like

My question is Can we access the the models in the postmigration

We have lots of utility classes which are DataObjectintensive. Can

How to use special characters in regular expression

HI all, I am new to regular expression.
Can any one please tell me the regular expression for characters which are used in regular expression like " [({. tetc.Is there any particular expression to prefix before using these characters

Expression:
< td .*? bgcolor = \" ( [^ \" ] +) \" \\s* .*? > ( .+? ) </td>
It will search for expression starting with <td ,
.*? means any characters zero or more than one,
then it will find bgcolor = , then literal \"... \(any char) is that specific char
[ ^ \" ] any character but not literal \",this means there has to be something between ".... " if empty then wont match ,+ is 1 or more times
Then again literal \ " , after that \\s* means zero or more num of spaces,
then again , .*? means any characters zero or more than one,
it will search for literal > , again any chars . * ?
Finally </td> will be searched.....!!
So all expressions having this particular structure will be
matched.
Output :
<td align="left" valign="top" bgcolor="ffffff" width="177">bla bla bla</td>

Use a regular expression to do this...
