Find/replace and regular expression problem

Hello, i'm using find and replace with a regular expression
for the first time. I have it checkmarked and it's finding my text
but it's missing (not highlighting) the ')' at the end of the line.
Here's my code:
[($[0-9]+US)]
it's supposed to find everything inside the square brackets -
but it misses the closing parenthesis after . I need
to find this string and replace with nothing to remove the string
from any/all pages. Is there a reason why it's missing the closing
parenthesis? I was actually able to add a few more parenthesis
(e.g. "))))") before OR after the closing square bracket and it
still found the original text minus the closing bracket and the
extra parenthesis didn't prevent the text from being found.
Any help is appreciated!

That's not how square brackets work
Try:
$\$\d+US$
A left parens, followed by the dollar sign, followed by at
least one
digit, followed by US,
followed by a right parens.

Find/Replace Using Regular Expressions

Can someone help me with this...I am using Regular expressions to
FIND:
http.*lid=([^&"]*)[^"]*
REPLACE:
$set(\1,ID_id,code)$
So that in the following it will change this:
a href="http://www.test.com/shc/s/home_10153_12605?lid=Search" rilt="Search"
To this:
a href="$set(Search,ID_id,code)$" rilt="Search
Those expressions work in Notepad++ but when i use dreamweaver it just replaces the http... with "$set(\1,ID_id,code)$" and doesnt reference the "search"
Any help?
Thanks

Let me begin by saying I'm a complete idiot with DW's Reg Ex. I use Search Specific Tag whenever possible. See screenshot below.
Try this on your Current Document to see if it works. Then make a back-up copy of site before attempting it on Entire Local Site as you cannot "Undo" this process.
Good luck,
Nancy O.

Pattern and Regular Expression problem

Hi all!
I have trouble with constructing a pattern.
Consider the following:
import java.util.regex.*;
public class Parser {
public Parser() {
String pattern = "<i18n:message(.*)/>";
String myline = "<INPUT type=\"button\" name=\"cancel\" value='<i18n:message key=\"EXP.EP.EPDATES.CANCEL\"/>' class=\"normal08\" onClick=\"javascript:disableInput();document.panel_menu.submit();\"/>";
Pattern p = Pattern.compile(pattern);
Matcher m = p.matcher(myline);
while ( (m.find()) ) {
System.out.println(m.group());
public static void main(String[] args) {
new Parser();
How should I construct the pattern in order to extract from the string myline just the following sequence: <i18n:message key=\"EXP.EP.EPDATES.CANCEL\"/>
It seems that using the pattern I wrote, it continues the match until the last appearance of "/>", and I need to have the match done until the first appearance of "/>".
Thanks a lot.

No, modify it to (.*?).Hey, unky. Would you mind schooling me a bit here?
"<i18n:message(.*?)/>" right?
against "<i18n:message key=\"EXP.EP.EPDATES.CANCEL\"/>' class=\"normal08\" onClick=\"javascript:disableInput();document.panel_menu.submit();\"/>"
I think I understand, but would appreciate confirmation or correction.
.* is zero or more of anything. The ? makes it reluctant (also called lazy?).
So .* is compared against nothing, succeeds, and the regex moves on to the next character.
This doesn't match / so regex backtracks and tries to match .* against the space, which succeeds, but then / doesn't match against the k in key
So we backtrack, and reluctantly add the k to what .* matches.
We keep adding a character to .*'s match every time the next character isn't a /.
Eventually, .* matches everything up to and including the quote before the first />.
At this point, the / and > literals match, and we're done.
Yes?
And we needed to make it reluctant, else the .* would have started by matching as much of the string as it could, gobbling up all of it, and then backtracking to give the /> literals their match at the end of the string.
Yes?
Thanks!

Find text using regular expression and add highlight annotation

Hi Friends
Is it possible to find text using regular expression and add highlight annotation using plugin

A plugin can use the PDWordFinder to get a list of the words on a page, and their location. That's all that the API offers for searching. Of course, you can use a regular expression library to work with that word list.

Replace without regular expressions

Hi,
Is there a standard java library function that can perform a search and replace WITHOUT regular expressions. Its not so much that I dont want to search by regular expressions, but whenever i have a "$" sign in my replace string it'll chuck a poo. Also, i'm sure regexp has to be much slower.
thanks,
Robert.

Wateva, I'll figure it out. I just thought I might be
missing a really simple function or somthing.
Thanks - and enjoy your 'duke dollars' :pFeel free to ask a more detailed question. I don't know how to answer something as general as what you posted. Provide some code, give us an example, tell us what you expect to happen. My sample showed you how to replace a dollar sign, which - as best as I can tell - is the problem you described having.
I've always considered replaceAll() to be pretty simple...

Replacing a Regular Expression by another

I want to replace a regular expression by another regular expression..i.e
if my input is : <tag>-1
output should be : <tag-1>
as the integer value changes for each tag I cannot hard code.I am able to match it using regular expression ">-\\d" but how do i replace it??
Any workarounds would also be appreciated.
Thanks in advance

It's not totally clear what you're asking for, but it sounds like something like this:
str = str.replaceAll("<tag>-(\\d+)", "<tag-$1>");Test it, and let me know if you have questions about what it's doing.
Check out [http://www.regular-expressions.info] for a great regex tutorial.

Help with Java and Regular Expression

Hello,
I have one line of Java and regular expression that I got from the web :
String[] opt;
opt = line.split("\\s+(?=([^\"]*\"[^\"]*\")*[^\"]*$)");
If "line" contains :
1 "Hello World"
this code would give me :
opt[0] : 1
opt[1] : "Hello World"
which is almost what I would like to do except for the double quotes. I wonder if someone could please help me change the regular expression so that it would return :
opt[0] : 1
opt[1] : Hello World
Thank you and Best Regards,
Chris

It looks to me like this is a line from a space delimited file so you should use one of the free CSV parsers such as http://opencsv.sourceforge.net/ . These will handle the quotes properly even if a field actually contains a quote.

GUI Based tool for search and replace using regular expression

Hi,
I have developed this small tool which can be used for search and replace in multiple files using reqular expressions.
Features:
1. Full regular expression
2. GUI based with Highlighted results
3. Preview for replace available
4. Pure Java based.
5. Its like unix sed and grep
Please visit below site for download/more information :
http://sourceforge.net/projects/regexsearchrepl/
Thanks,
Hitesh Viseria

I agree with you, it cannot compete grep/sed/awk combination. I couldnt find anything even close to grep/sed for windows which will also have a preview and most important, free. That is what made me write this tool. I am trying to
improve its performance and more features like history etc.
Any suggestions on additional features are most welcome.

Regular Expressions - Problem

Hi @ all,
I need a complicate regular expression, I don´t know.
I have a big folder with many .htm pages (800-1000) and I have to do the following:
http://www.domain.de/ab%32-xyz?myshop=123
I have to delete the "ab%32-xyz", the problem is, that in this are, there could be every symbol, letter or number.
So the area between "http://www.domain.de/" and "?myshop=123" (these 2 areas are everytime identical in all documents) shoud be deleted.
Could everyone say me, how to do this with regular expressions in dreamweaver?
Thanks,
Felix
P.S.: Sorry, my Engish is not so good, I´m from Germany

Do you want to replace the random text with anything?
If not, this is how you do it in DW:
Make a backup of the folder you want to edit, just in case anything goes wrong
Edit > Find and Replace
In the Find and Replace dialog box, select Folder from the "Find in" drop-down menu, and select the folder you want to work with.
Select Source Code from the Search drop-down menu.
Put the following code in the Find text area:
(http://www\.domain\.de/)[^?]+(\?myshop=123)
Put the following code in the Replace text area:
$1$2
In Options, select the "Use regular expression" check box.
Click Replace All. Dreamweaver will warn you that the operation cannot be undone in pages that aren't currently open. As long as you have made a backup, click OK to perform the operation.

[SOLVED]ZSH and regular expressions

Hi
I am getting into regular expressions and i have noticed that with my .zshrc file i have some problem. In bash this expression works:

Could you try being a bit more specific?
Firstly, i am sorry i didn't post the output. I should have know better.
Secondly, chill out.
I have used above regex with grep command. Output from terminal is:
zsh: bad pattern: ^[^#]
In bash it works perfectly.
If i issue "setopt re_match_pcre" i have the same ouput as above.
EDIT: If i issue "unsetopt no_match" it actually works but i have to change the regex from "\^\[^#]" to "\^[^#]" otherwise i get the same output as above. In bash both options work.

Finding URLs using regular expression.

I have an requirement where user will type some text containing URLs like "Please visit this site http://www.google.com/e/qHvQcWco`~!@#$%^&*()-7747. Thank you". This text has to be modified as below before saving it to the database.
"Please visit this site <a href='http://www.google.com/e/qHvQcWco`~!@#$%^&*()-7747'>http://www.google.com/e/qHvQcWco`~!@#$%^&*()-7747</a>. Thank you"
I am using regular expression (http|https)://.+?\\s which marks the end of the url with a white space character.This pattern doesn't work if the URL is located at the end of the string since there will be no space at the end.
For example if the string is "Please visit this site http://www.google.com/e/qHvQcWco`~!@#$%^&*()-7747" the regex will fail.
My acutal problem is to find the URL irrespective its position within the string.
Pattern urlPattern = Pattern.compile("(http|https)://.+?\\s", Pattern.CASE_INSENSITIVE);
Matcher matcher = urlPattern.matcher(plainText);
Map stringIndexMap = new HashMap();
//Searching the input string for urlPattern...
while(matcher.find()) {
String urlString = matcher.group();
//Storing the urls in a hashmap with their indices as keys....
stringIndexMap.put(new Integer(matcher.start()), urlString.trim());
Set keySet = stringIndexMap.keySet();
Iterator it = keySet.iterator();
//Iterating over the hashmap containing urls...
while(it.hasNext()) {
String urlString = (String) stringIndexMap.get(it.next());
* Replacing the url string in the input text with <a href="#" onclick="window.open('<urlString>')"
* using String index
clickableURLString.replace(clickableURLString.indexOf(urlString),
clickableURLString.indexOf(urlString) + urlString.length(),
"<a href=\"#\" onclick=\"window.open('" + urlString
+ "')\">" + urlString + "</a>");
return clickableURLString.toString();

The end of the input is '$' as a regex.
import java.util.regex.*;
public class Prasanna{
public static void main(String[] args){
 String text
= "Please visit this site http://www.google.com/e/qHvQcWco`~!@#$%^&*()-7747";
// String regex = "(http|https)://.+?(?:\\s|$)"; // this works
 String regex = "(http|https)://[^ ]+"; // this also works
 Pattern pat = Pattern.compile(regex, Pattern.CASE_INSENSITIVE);
 Matcher mat = pat.matcher(text);
 while (mat.find()){
 System.out.println(mat.group());

Interesting Regular Expression Problem

Hi - I am fairly new to Java, but have some reg exp experience.
Basically, I would like a regular expression to strip elements out of a text format. The elements are delimited by curly braces, very similar to Java. The problem is that the elements may contain other elements - the format is hierarchical. I need to extract the whole element, including its children.
For example, I need to extract the B element from
[A]
a1 1
a2 2
b1 1
b2 2
[C]{
c1 1
c2 2}
[C]{
c1 3
c2 4}}
and the answer should be
b1 1
b2 2
[C]{
c1 1
c2 2}
[C]{
c1 3
c2 4}}
The nature of the format is not fixed - I won't know how many child elements the B element contains.
Can this be done using regular expressions, or do I have to write a custom string handling function?
Thanks for any help.

:-) And I still don't understand it!It's quite easy though ;-) Suppose a word w is generated by some grammar.
If this grammar is regular you can write word w as xyz where y is not the empty
word and |x| < p. if w is generated by a regular grammar then xy^nz
(n occurrences of y) can also be generated by the same grammar. That's
the 'pumping' giggle part.
Now suppose the language of nested parentheses is a regular language.
All you have to do is find a word w = xyz where xy^nz is not part of the language.
Let w= ((())) and x= ((, y= ( and z= ))), obviously xy^nz is not a properly nested
parentheses word for n > 1. Note that every generated word in that language,
long enough has to have that value p, where xy^nz |x| < p and xy^nz in the language.
The pumping lemma giggle for context free languages is almost the same:
you have to find two positions where the pumping fails/succeeds.
kind regards,
Jos (huhuh, he said 'pumping' ;-)

[solved] Need a little help with sed and regular expressions

Hello!
I am shure this is something easy for most of you
I want to make a script, which converts filenames of my ripped MP3s (replaces '_' with spaces, removes leading track numbers...)
But I have some problems:
j=$(echo $j | sed 's/_\+/ /g')
j=$(echo $j | sed 's/^[0-9]{0,3}//g')
j=$(echo $j | sed 's/[^ ]-[^ ]/ - /g')
j=$(echo $j | sed 's/_\+/ /g') << this is working fine (converts all "_" to spaces)
j=$(echo $j | sed 's/^[0-9]{0,3}//g') << is NOT working, why??
For Example in "01-somebody_feat_someone-somemusic.mp3" the leading "01" number is NOT being removed..
j=$(echo $j | sed 's/[^ ]-[^ ]/ - /g') << how can I insert spaces before and after the "-"?
So that "someone-somemusic" becomes "someone - somemusic" (but only where "-" is surrounded by letters)

For sed, you must escape { and } to use them as you want (just slap a \ before them).
For the last expression, capture the letter before/after the dash -- use $ and $ -- and then substitute it for something like "\1 -" and then "- \1". You'll want to split this into two pieces, one for the front and one for the back so you can get "somemusic -someband" the way you want without a bunch of cases.
Edit: Or, you could just do a replace for "-" to be " - " and then have another expression to reduce spaces. I see you've used \+ before, so I'm guessing you can figure that out
Also, sed has the -e switch so you can do multiple different expressions with one invocation.
Also (also), have you looked into something like Picard with automatic track renaming? You can even customize how they are renamed.
Edit (2): Also^3, check out prename. There are different versions, ones which use PCRE and ones that use other standards, but it is for renaming files based on regular expressions, which is what you're doing. In any case, you might want to put you script into the User made scripts thread when you feel more comfortable and get some more critiquing, if you're interested.

Extended Replace with Regular Expressions

I am trying to figure out how to user regular expressions in
HomeSite 5.5 extended search and replace.
I am trying to find all matches to: FooText
And replace with: <sometag>FooText</sometag>
I have been able to get the find part working with reg ex:
*[A-Za-z0-9_
><.="']*
However, I have not been able to figure out what to put in
the replace box. I have tried different combinations of syntax with
"\1" for the first match of the reg ex in the search field, but
nothing has worked.
Can someone help me out with the syntax for what I should
enter in the replace field?

SQL>with t as(
2 select 1 id,'a aa ---- ss-ee -' str from dual union
3 select 2, 'a aa -------- ss-ee ---- - - -' str from dual union
4 select 3, '-' str from dual union
5 select 4, '----- -- -a -' str from dual union
6 select 5, '-a-a-a-a----a-a-a-' str from dual
7 )
8 select id,
9 str,
10 trim(trim('-' from regexp_replace(str, '( |-){2,}', '\1'))) new_str,

Question sql and regular expressions

I am trying to write a query where a like with a regular % wont work.
select <cols>
from <tab>
where col2 starts with 'SOME CHARACTERS' The field can have 0 or more empty spaces before there are more characters. However, I know what those characters are. How do I do 0 or more characters?
select mycols
from myemptable
where empname like 'JO%JO'There could be 0 or more empty spaces between JO and JO, but the next character is 'JO' . This is a general case. So it could be something else.
so % won't work. since i could get back 'JO HA JO' which I dont want.

Regular expressions where introduced with Unix in 1973.
It shouldn't be difficult to find online resources.
You seem to belong to the big class of users in this forum who doesn't know how to use the Internet, or find that to demanding.
The solution can of course be found in 5 minutes, of 2 to start my database especially for you at almost midnight.
with a as (select 'JO JO' col1 from dual
 union
 select 'JO JO' col1 from dual
 union
 select 'JO HA JO' col1 from dual
 union all
 select 'JO JO BLEH' from dual)
 select * from a where regexp_like(col1,'^JO( +)JO.*$')
You find out what it means as exercise.
