Stumped on Regular Expression in ReReplace

Hi Folks,
I'm new to regular expressions and I'm stumped on two of
them. I have a book on order from Amazon on this, but can't wait 3
days for it to arrive. Any help would be greatly appreciated!
1. I need to remove all HTML tags from a string EXCEPT for
certain ones, such as <img> <a> etc. The expression
<cfset vResp = REReplace(vResp, "<[^>]*>", "",
"All")> removes all, but I can't figure out how to exclude the
<img>, <a>, etc. tags.
2. I'm trying to figure out how to remove repeated characters
that could be /n or /r or /f, leaving just the first occurance.
i.e. how to strip out white space between lines in an html file.
Thanks!

Use the inline modifiers. "(?i)" makes the regex case insensitive until the next "(?-i)"; "(?i:xyz)" makes only that group case insensitive.

Regular expression on form value

I have a form value that I need to add a regular expression to the end so I can pick up any characters after the form value.
Example if someone enters Jones then I want to make sure the value could also search Jones Jr or Jones Sr.
Basically add a space and any characters a-z to the form value.
Here is my attempt but lost on regular expression part:
REReplace ("form.myvalue","[[:space:]]","Not sure what the regular expression would be here?","ALL")

This will replace "Jones Jr" and "Jones Sr" in the following text:
"this is a test text Jones Jr and Jones Sr"
ReReplaceNoCase("your_text_in_which_you_want_to_replace",
"#form.myvalue#[[:space:]][a-z]*", "replacement_text", "ALL")

Regular Expression in CF ?

Hi
I have the following line from an rss feed
#weather_xml.rss.channel.item[x].description.xmlText#
At present it outputs as
Thursday: sunny, Max Temp: 8°C (46°F), Min Temp:
4°C (39°F)
Is it possible using regular expressions or another method,
that after each comma the script will insert a tag so
all the data is not displayed on one line ?
Any ideas ?

You do have to provide the basic CFML syntax of hash|pound|#
signs
around the function inside a
<cfoutput></cfoutput> block so that the
ColdFusion application server knows this is a statement to be
resolved,
not just text to display.
I.E.
<cfoutput>#replace(weather_xml.rss.channel.item[x].description.xmlText,
',', ' ', 'ALL'>#</cfoutput>

Regular Expression / replace Function Help

The problem:
cfset myString = "i am a big boy"
cfset outputString = replace("i am a big
boy","i","you","all")
Wrong Output:
you am a byoug boy
Intended Output
you am a big boy
How do I achive that output.

Your first example had only one sentence. That's why I gave
that answer.
Anyway for your real question, you need to use regular
expressions
#rereplace(myString,"i\s","you ","all")# - will give u
you am a big boy you am a big boy you am a big boy you am a
big boy.
\s looks for a whitespace character after the letter i. So
that way it will not change the letter i in big

Regular Expression Trouble

Hello All, Happy Holidays.
I'm creating a component in an application that is similar to
Facebook's "News Feed" feature. This feature lists rows from a
database which may contain some 'special text' that needs to be
converted to HTML. Note: I am storing the 'special text' in the
database instead of the actual html code to save space in the
database in case the name of the object is very long.
Here's what I'm trying to do:
In the database a record might look like this:
On 12/25/06 [user:253]John Smith[/a] Logged On.
When I display the table I want to convert it to the
following:
On 12/25/06 <a href="user_info.cfm?userId=253">John
Smith</a> Logged On.
I've been able to create the following regular expression
which does a good job converting the text to a link, but I am
unable to get the uniqueID (253) from the string. Note: Description
is the name of the column that is being processed.
<CFSET temp = ReReplace(Description,'\[User:.\]','<a
href="user_info.cfm?userID=253">','ALL')>
<CFSET temp =
ReReplace(temp,'\[/a\]','</a>','ALL')>
Is there a way I can convert the string in one regular
expression? Also, how can I get the number value after the colon
(:) and insert it into the replacement string?
Also, to complicate things, the string may have multiple
instances of 'special text'. For example:
On 12/25/06 [user:253]John Smith[/a] modified
[user:262]Captain Picard's[/a] account
Thanks for your help!

If I read your requirement correctly, you should replace
this:
\[user:([^\]]*)](.*)?\[/a]
With this:
<a href="user_info.cfm?userId=\1">\2</a>
The bit you were missing from your regex was capturing the
subexpressions
for the ID and the name. Can I suggest you read this:
http://livedocs.macromedia.com/coldfusion/7/htmldocs/00000990.htm,
and have
a bit of an experiment.

Writing a particular regular expression

I'm trying to come up with a regular expression that I would use to scan a list of strings and store the ones I want. I have most of it working properly but a section of it stumps me.
In order to make my problem as clear as possible, I'll assume that I have some strings that look like the following:
<catapult>
<yay>
<griffin>
<goo>
<dog_man>
<ok>
<>
What I would like to do, is to make the entire string a match, as long as it doesn't contain certain characters and certain substrings.
For instance, say, as long as it doesn't contain the characters "y" or "x", and doesn't contain "cat" or "riff", and is not "goo" then it's a good match. So, the first four in my list should not match and the last three should.
What I tried to do, was create a set of just negating the characters and the substrings contained in groups, which I didn't want. It looked something like this:
<(?:[[^yx]&&[^(?:.*cat.*)]&&[^(?:.*riff.*)]&&[^(?:goo)]]*)>
Apparently this did not produce the results I desired. I assume this can be done but I just can't figure out how.
I hope I made sense. Does anyone have any idea what I need to do?

Wow, thanks so much. That's really helpful. No wonder I couldn't get it. I looked over the tutorials so that helped to clear things up a bit.
Actually, sjasja, I would've done something like that but what I mentioned was just a portion of the patterns that I wanted to match, so although I'm inexperienced with complicated regexes, I figured it would be much neater and concise if I could get it to do what I wanted.
There is a slightly longer, but similar, expression that I would like to match but I suspect I might've made a mistake.
What I want is to have examine a line, and group every instance of what I find within '[ ]'. The substring that would match would be be found in between < >. The first part I would like to be a group of characters (or no characters at all) which don't contain cat, CAT, x or y (anywhere in this area). This time though, I would like something else before the end bracket, so I don't know if I should include the '>' like in the original expression you provided, or not. Following it should be 'cat' or CAT' and then '[ ] >'
What I'm trying to get this pattern to match, are strings like these:
<cat [yay]>
< something CAT [this] >
< dog cat [cat3]>
but not like these:
< cat CAT [yay] >
<catch [HI]>
< CAT CAT [ ] >
What I attempted to do was write the regex as
<\\s*(?:(?!cat|CAT)[^xy])*(?:cat|CAT)\\s*\\[(.*)\\]\\s*>
but I think that (?:(?!cat|CAT)[^xy]) might also match up with the trailing characters, which would result in bad matches. Am I mistaken in this?
I'm sure you're all busy people, but a tip in the right direction would be great.
Thanks again.

Logical AND in Java Regular Expressions

I'm trying to implement logical AND using Java Regular Expressions.
I couldn't figure out how to do it after reading Java docs and textbooks. I can do something like "abc.*def", which means that I'm looking for strings which have "abc", then anything, then "def", but it is not "pure" logical AND - I will not find "def.*abc" this way.
Any ideas, how to do it ?
Baken

First off, looks like you're really talking about an "OR", not an "AND" - you want it to match abc.*def OR def.*abc right? If you tried to match abc.*def AND def.*abc nothing would ever match that, as no string can begin with both "abc" and "def", just like no numeric value can be both 2 and 5.
Anyway, maybe regex isn't the right tool for this job. Can you not simply programmatically match it yourself using String methods? You want it to match if the string "starts with" abc and "ends with" def, or vice-versa. Just write some simple code.

Help in Regular expression

Hello..
I wanted to write a regular expression to match the foll string..
 
 NEW ORLEANS, Louisiana (CNN) 
-- Two years after Hurricane Katrina devastated coastal areas of Louisiana and Mississippi, residents say much of America has forgotten their plight.
 
I tried doing..
Matcher matcher= Pattern.compile(" ([^<^>]+?)", Pattern.CASE_INSENSITIVE).matcher(story);
Its not working...
is there any other soln?

Theres probably a better way to do this but here's a way that works.
import java.util.regex.*;
public class RegexTester{
public static void main(String[] args){
 String text =

 String regex = ">((?:\\s*[\\S&&[^<>]]+\\s*)*?)<";
 Pattern p = Pattern.compile(regex);
 Matcher m = p.matcher(text);
 while(m.find()){
 System.out.println("Match: '" + m.group(1) + "'");

Help in regular expression matching

I have three expressions like

2) [(y2008M5)(y2011M3)] or [(y2009M5)(y2010M12)]
3) [(y2009M1d20)(y2011M12d31)]
i want regular expression pattern for the above three expressions
I am using :
REGEXP_LIKE(timedomainexpression, '???[:digit:]{4}*[:digit:]{1,2}???[:digit:]{4}*[:digit:]{1,2}??', 'i');
but its giving results for all above expressions while i want different expression for each.
i hav used * after [:digit:]{4}, when i am using ? or . then its giving no results. Please help in this situation ASAP.
Thanks

I dont get your question Can you post your desired output? and also give some sample data.
Please consider the following when you post a question.
1. New features keep coming in every oracle version so please provide Your Oracle DB Version to get the best possible answer.
You can use the following query and do a copy past of the output.
select * from v$version 2. This forum has a very good Search Feature. Please use that before posting your question. Because for most of the questions
that are asked the answer is already there.
3. We dont know your DB structure or How your Data is. So you need to let us know. The best way would be to give some sample data like this.
I have the following table called sales
with sales
as
 select 1 sales_id, 1 prod_id, 1001 inv_num, 120 qty from dual
 union all
 select 2 sales_id, 1 prod_id, 1002 inv_num, 25 qty from dual
select *
from sales 4. Rather than telling what you want in words its more easier when you give your expected output.
For example in the above sales table, I want to know the total quantity and number of invoice for each product.
The output should look like this
Prod_id sum_qty count_inv
1 145 2 5. When ever you get an error message post the entire error message. With the Error Number, The message and the Line number.
6. Next thing is a very important thing to remember. Please post only well formatted code. Unformatted code is very hard to read.
Your code format gets lost when you post it in the Oracle Forum. So in order to preserve it you need to
use the {noformat}{noformat} tags.
The usage of the tag is like this.
<place your code here>\
7. If you are posting a *Performance Related Question*. Please read
 {thread:id=501834} and {thread:id=863295}.
 Following those guide will be very helpful.
8. Please keep in mind that this is a public forum. Here No question is URGENT.
 So use of words like *URGENT* or *ASAP* (As Soon As Possible) are considered to be rude.

Hi,
Try this

VTThat won't work as it's expecting at least two characters with the first having to be a-z (lower case) or space or "-" followed by A-Z (upper case) or space or "-".
The correct way is either:
[a-zA-Z -]or
[[:alpha:] -]using the alpha set is often preferable as it can work differently with different character sets/languages rather than restricting to just the a-zA-Z ranges.
Generating a reference for your own database characterset/language can be useful...

Urgent!!! Problem in regular expression for matching braces

Hi,
For the example below, can I write a regular expression to store getting key, value pairs.
example: ((abc def) (ghi jkl) (a ((b c) (d e))) (mno pqr) (a ((abc def))))
in the above example
abc is key & def is value
ghi is key & jkl is value
a is key & ((b c) (d e)) is value
and so on.
can anybody pls help me in resolving this problem using regular expressions...

Bracket in Regular Expression constant?

I am a bit puzzled by the behavior I am experiencing in LV 2011. I hope to get some light from experts out there.
I am trying to parse a messy ASCII header file and after having split it into individual lines (strings), I use the "Match Regular Expression" function to remove some of the info before the substantial information.
Some of the strings include square brackets ([, ]), which are special characters for the function, therefore, as documented in the help, one needs to precede them with a backslash.
Example:
I want to parse the following line:
#PR [PR_DEV,I,2]
One way (which I am using because of considerations related to the rest of the header) is the the following:
Note that the first string constant is using "Code Display" whereas the second one is using "Normal Display".
Why did I not put a backslash in front of the bracket in the first string, you may ask? Well, I did, but it disappeared after I typed the other characters. And reverting to "Normal Display" did not restore it.
Of course, the first version does not parse the input string correctly, whereas the second one does it fine.
In other words, the custom display string (which is convenient for cryptic codes such as \s* or to distinguish between space and tab...or simply ENTER tabs!) seems to mess up with the \[ combo (likewise with the \] one).
It is not a huge deal. I can use the "Normal Display" mode, but I tend to think that this qualifies as a hidden "feature". And again, it is still a pain in the ... when dealing with special characters such as tabs, etc...
Solved!
Go to Solution.

I think that [ is a special character which needs to be preceded by a backslash, but it is not one of the defined backslash characters (like \s). So, you need to put in two \\ to get one \ while in '\' Codes Display.
You can put in any character by using \xx where the xx is a hex character using only upper case letters for A..F. I converted the strings to byte arrays and tried to see what made the arrays match and the Match work.

Need help with regular expression

I'm trying to use the java.util.regex package to extract URLs from html files.
The URLs that I am interested in extracting from the HTML look like the following:
http://forum.java.sun.com -
So, the URL is always preceeded by:

and then followed by a space character and then a hyphen character. I want to be able to put all these URLs in a Vector object. This doesn't seem like it should be too difficult but for some reason I can't get anywhere with it. Any help would be greatly appreciated. Thanks!
