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.

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.

URL paths and regular expressions in ASDM

Some background info - I've recently switched to an ASA 5510 on 8.4(3) coming from a Checkpoint NGX platform (let's say fairly quickly and without much warning ). I have a couple questions and they're kind of similar so I'll post them up. I've read docs about regex and creating them both via command line and ASDM, but the examples always seem to include info I don't need or honestly something I don't understand yet (mainly related to defining class\inspect maps). If someone could provide a simple example of how to do these in ASDM that would help a lot in understanding how regular expressions are properly configured. So here we go.
I know this is basic but I need to make sure I understand this properly - I have a single web server (so this won't be a global policy) where I need to allow access to a specific URL path\file and that's it. So we'll call it \test\testfile.doc. Any other access to any other path should be dropped. What's the best way to do this in ASDM (6.4)? I think if I saw a basic example for this I could figure out next few questions but I'll post them as well just in case.
I have another single public web server (again this won't be a global policy) where I'd like to specify blocking file types, like .php, .exe., etc... again a basic example would be great.
Lastly, and this is kind of related, but we have a single office/domain and sometimes we get spam from forged addresses appearing to be from our domain. On Checkpoint I used to use its built-in SMTP security server and could define if it received mail from *@mydomain.com to drop it because we would never receive mail externally from our own domain name. I saw something similar with ESMTP in ASDM and it looks kind of like how you set up the URL access mentioned above. Can I configure this in ASDM as well, and if so how?
TIA for your help,
Jordan

ACE20 Module, webservices and regular expressions.

Hello All,
I am trying to loadbalance requests for webservices in a serverfarm. But for some reason, ACE20 module y not making matches on the requests.
We have a serverfarm Prod1 with 2 real servers and another serverfarm named WSDL with other 2 real servers.
The idea is the following, if we receive the following string, /App.WebService, the ACE should redirect it to serverfarm Prod1, but if it receives /App.WebService?wsdl, it should be redirected to WSDL.
Request with string /App.WebService --------------> ServerFarm Prod1
Request with string /App.WebService?wsdl -----> ServerFarm WSDL
We use regular expression in L7 class maps to make the loadbalance to happen.
class-map type http loadbalance match-all APP.WEBSERVICES-L7-SLB
2 match http url /App\.WebService\?wsdl
class-map type http loadbalance match-all APP-L7-SLB
2 match http url /App\.WebService
policy-map type loadbalance first-match L7_SLB-POLICY
class APP.WEBSERVICES-L7-SLB
    serverfarm WSDL
class APP-L7-SLB
    serverfarm Prod1
class L4_SLB_DATAPOWER(9050)
    loadbalance vip inservice
    loadbalance policy L7_SLB-POLICY
    loadbalance vip icmp-reply
    appl-parameter http advanced-options HTTP_PARAM
    ssl-proxy server wildcard.test.org
    connection advanced-options TCP_PARAM
But the ACE20 Module seems to be removing the ?wsdl from the URL and only the class-map called APP-L7-SLB is being matched.
Any comments or suggestions on why this could be happening?
Thanks in advance,
Fernando

Hello Kanwal and all,
Finally, after reading and reading I found a fix to this problem. Seems that the HTTP protocol uses the question mark (?) character as a delimiter for data appended to the URL. So, if you get the following:
www.test1.org/App.WebService?wsdl
If you configured a L7 class map to parse the URL, it will only parse until the question mark (?).
So you need to create a PARAMETER-MAP changing the URL delimiter start. Here is an example:
parameter-map type http HTTP_PARAMETER_MAP_WSDL
persistence-rebalance strict
set secondary-cookie-delimiters ;!@?
set secondary-cookie-start ;
I used the semicolon ( ; ) as delimiter.
Hope this helps.

PrintWriter issue with Directory Traversal and Regular Expression

This is a follow up to my previous question on the forum. I am developing a program traverses the hard drive for information. If it finds the said information in any of the file (based on the regular expression wriiten) it must print the output into the file. Currently I am able to traverse the harddrive perfectly, the regular expression and the search is perfect and when I print the output into the local console, I am able to derive perfect results. But when I use the PrintWriter to write the output into the flight, it writes NOTHING into the file. I have been scouring all over the Internet for an answer, but havent been able to find. Would highly appreciate if someone can tell me what I am doing wrong and provide some guidance on how to get it right.

Question about match regular expression

Colleagues,
Very stupid question. I would like to get substring between "..." symbols. For example, string 02 July from Explosion occurred on "02 July", 2008.
How to do this with single Match Regular Expression?
For example such expression ".*" will give me "02 July":
But I would like to get it without " symbols!
I tried this "[~"]*" and this "[~"].*", then read this and this , and all without success... But I'm sure it should be possible. Can you help me?
Andrey.
PS
This regular expression should give exactly the same output as following construction:

I'm only using 7.0 now, but you can do this with Scan from String...

[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:
\^\[^#]
but not also in zsh. I have also noted that regular expression works fine with other zshrc configurations found in archwiki (like grml) but i want to have my configuration. And i really can't find what command make a difference

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.

A question about using regular expression

Hi,
This is a part of HTML file.
how
are
you
I want to search string between each pair of , tags by using Regular Expression.
For example:
how
are
you
If I use following method
String regx="(.+)";
Matcher m=Pattern.compile(regx).matcher(str);
int currentLoc=0;
while(currentLoc<str.length()){
 if(m.find(currentLoc))
 System.out.println(m.group(1));
 currentLoc=m.end();
}The content between first and last will be searched.
How to solve this problem?

Use a non-greedy match:
(?s)(.+?)(?s) makes the dot match the line terminator (same as setting the dot all option)

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.

Question about creating regular expression

Hi!
I am creating parser for the specific configuration file. Now I have got small problem: I need to find the line with text in format "key value".
For example I have this text file:
entry {
     key value
     key2 value2
     entry2 {
     }I wish to find, using java.regex, these two lines: "key value" and "key2 value2". But how?

Is your problem that you don't understand regular expressions? If so then this might help. Or is your problem you don't understand Java regular expressions? If so then this might help. Or is your problem that you don't understand how to read lines of a file? If so then this might help.

[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.

Url pattern tag and regular expression

I am trying to set up my web.xml in Tomcat 4.1.3 container to go to one page if letters are entered in last part of url or go to another page if numbers are entered in the last part of a url.
For example if here is how the url would be set up where the url will go to either the all numbers location or the non numbers location:
Any number entry for last part of url which could be something like 343
http://127.0.0.1:8080/theapp/pack/weburl/343
Any non number entry for last part of url which could be something like abec
http://127.0.0.1:8080/theapp/pack/weburl/abec
My attempt below is not working because it doesnt seem to take the regular expressions. But if I manually put in letters such as: <url-pattern>/pack/weburl/ab</url-pattern> it would take me to the correct page. How does web.xml work with regular expressions inthe url-pattern tag??
<servlet>
<servlet-name>Number</servlet-name>
<servlet-class>pack.Number</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Number</servlet-name>
<url-pattern>/pack/weburl/\d*</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>NotNumber</servlet-name>
<servlet-class>pack.NotNumber</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>NotNumber</servlet-name>
<url-pattern>/pack/weburl/[A-Za-z]</url-pattern>
</servlet-mapping>

Sorry, this pattern can't take regular expressions.
Referring to the servlet spec section 11.2 which defines these mappings
In the web application deployment descriptor, the following syntax is used to define
mappings:
� A string beginning with a �/� character and ending with a �/*� postfix is used
for path mapping.
� A string beginning with a �*.� prefix is used as an extension mapping.
� A string containing only the �/� character indicates the "default" servlet of the
application. In this case the servlet path is the request URI minus the context
path and the path info is null.
� All other strings are used for exact matches only.As an alternative, I would suggest that you match the request to a filter, and then use some logic based on request.getURI() to determine which resource to forward to from there.

JFormattedTextField Mask and regular expression

Hi,
I have to allow a user to enter numeric values only. The first 3 digits are mandatory, followed by a space, followed by a maximum of 20 digits,
I am trying to use the regex formatter from Sun at
http://java.sun.com/products/jfc/tsc/articles/reftf/
Plus, I wanted to have a mask as well, so that the user does not have to type-in the space.
So far, I haven't had any luck in getting to implement both.
Any helps would be greatly appreciated.
Thanks

Hello,
... so that the users don't have to type-in the space?I don't see a solution with regular expressions for that, although I'm not an expert in that field. Let's take an example with a more "visible" character like "123-456", regex only checks, but doesn't display or jump over separator literals.
Presently I can only see a solution in using a normal MaskFormatter
    MaskFormatter mf1;
    try
    { mf1 = new MaskFormatter("### #####");
    catch (ParseException e)
    JFormattedTextField tf = new JFormattedTextField();
    mf1.install(tf);If you install a field to a maskFormatter it doesn't oblige you to fully fill up the mask, as happens if doing a
JFormattedTextField tf = new JFormattedTextField(mf1);
This nicely jumps over the blank (or any other literal). However, you
have to check whether at least three ciphers have been input. This could be done either in an Action- or Focus(Lost)Listener or by means of an InputVerifier.

Basic question on this Regular Expression syntax

The below query returns the string before the first comma.
SQL> select regexp_substr('JACK,AND,JILL,WENT', '[^,]+' ) FROM DUAL;
REGE
JACKWhat does
[^,]do? Does it just mean, look for comma (,)
What does the plus sign in
'[^,]+'do?
These are not mentioned in the 10GR2 's SQL Reference for REGEXP_SUBSTR function, hence i am posting this in OTN.
