Removing spaces in a value

What is the easiest way to remove the spaces form a string or replace them with underscore i.e. change "The red car" to "Theredcar" or "Theredcar"?
Thanks.
Pedro

I realize you have a lot of excellent responses to this question already!! Some serious AppleScript-gun-slinging going on in this thread, I like!!
Just to throw another method into the mix:
<pre style="margin:0px;padding:5px;border:2px dotted green;width:630px; height:auto;color:#ffffff;background-color:#000000;overflow-x:auto;overflow-y:h idden;font-family:Verdana, Monaco, monospace;font-weight:bold;font-size:12px;"
title="Copy this text and paste it into your Script Editor application.">set theDog to display dialog "Enter the text to manipulate below:" default answer ¬
"The red car" buttons ¬
{"Cancel", "Remove Spaces", "Replace With Underscores"} default button 3
set {theText, theButton} to {text returned of theDog, button returned of theDog}
if theButton is "Remove Spaces" then
set theDelimiter to ""
else
set theDelimiter to "_"
end if
do shell script "echo " & quoted form of theText & ¬
"|awk 'gsub(\" \",\"" & theDelimiter & "\") {print}'"</pre>
Now you've got plenty to choose from and all these different approaches serve their own great purpose!! Happy scripting! Remember, there are always many different ways to achieve the results you're looking for.

Regular Expression to remove space in HTML Tag

Hello All,
My HTML string is like below.
select '<CityName>RICHMOND</CityName>
<StateCd>ABCD CDE
<StateCd/>
<CtryCd>CAN</CtryCd>
<CtrySubDivCd>BC</CtrySubDivCd>' Str from dual
Desired Output is
<CityName>RICHMOND</CityName><StateCd>ABCD CDE
<StateCd/><CtryCd>CAN</CtryCd><CtrySubDivCd>BC</CtrySubDivCd>
i.e. want to remove those spaces from tag value area having only spaces otherwise leave as it is. Please help to implement the same using Regular expression.

Hi,
It's unclear what you want. This site seems to be formatting your message in some odd way.
Post a statement like
SELECT '...' FROM dual;
without any formatting, to show your input, and post the exact output you want friom that, with as little formatting as possible. It might help if you use some character like ~ instead of spaces (just for posting; we'll find a solution that works for spaces).
To remove the text that consists of spaces and nothing else between the tags, you can say
REGEXP_REPLACE ( str
, '> +<'
, '><'
How is this string being generated? Maybe there's some easier, more efficient way to keep the bad sub-wrtings out of the string in the first place.

But it is not working.

How remove space in column ?

In a.newunit column I have spaces before data. I tried to use TRIM and LTRIM -- but doesn't work :(
What else I can use?
SELECT LTRIM(u.scode), LTRIM(a.newunit)
FROM unit u,
aaa_test a
WHERE LTRIM(u.scode) = LTRIM(a.newunit)

Can you explain what "doesn't work" means, preferrably with an example (i.e. DDL for the Unit and AAA_Test tables, INSERT statements, and a query that returns the incorrect results)?
TRIM will remove spaces at the beginning and end of a value, LTRIM will remove spaces at the beginning of a value. Potentailly, you don't really have spaces at the beginning of your data. Potentially, you are misinterpreting something (in which case seeing what constitutes "not working" is critical).

Remove spaces and special characters from a form field

Hi,
I am tragically new to all of this, but am trying to create a form in Adobe Acrobat 9. I am trying to use a Custom Format script to take inputs in a form field and automatically remove spaces and special characters (hyphens specifically). For example, if a user inputs "RAN-99 06" I would like it to change to "RAN9906." I found this script that will not let users input special characters
if (!event.willCommit) {
event.change = event.change.replace(/[\$#~%\*\*\^\-\+=\[\]\{\};\"\<\>\?\|\\\!]/g, "");
And that's okay, but I can't figure out how to disallow spaces. Also, the perference would be for a script to allow users to input the data as they like, but to clean it up after they leave the text field.
Thanks in advance!

From the description, I assume that the script is currently in the Keystroke event. In fact, that would be a most logical way to have it; simply ignore anything unwanted when entered.
If you want to allow the user to enter anything, but "clean it up" when done, you would place your code in the Validate event. You will have to adjust your Regular Expression so that it works globally, but that's the whole difference. This will change the value.
Note that you can also enter the code into the Format event. However, that would only change the visual representation of the value, but internally, the value would remain as entered.
Hope this can help.

XDOFX if-then-else command testing of space and numeric value

Hi,
I have the following xdofx statement in a RTF template to display the value of one variable or another, depending on the value it contains: (the variable can contains both space or null or a numeric value).
<?xdofx: If Amount_1 = " then 'display amount_2' else If Amount_1 = 0 then 'display amount_2' else 'display Amount_1' end if?>
Result: When Amount_1 variable contains space or null value, then this If-then-else statement works. But When Amount_1 contains a number such as 0, it gives error "SBL-OMS-00203" (when it's checked against [=" ] in If condition). What's causing this? Is XDOFX being confused to test a variable that supposedly a character string (default by testing against [ =" ]), but find a number in the variable?
Any work around solution? (So [=" ] and [=0 ] can both be specified against a variable in an if-then-else statement in XDOFX).
Thanks a lot.
A.

try
<?xdofx:if (Amount_1 =’’) then ‘display amount_2’ else if (Amount_1 =’0’) then ‘display amount_2’ else ‘display Amount_1’ end if?>or
<?xdofx:if (Amount_1 =’’) then ‘display amount_2’ else if (to_number(Amount_1) =0) then ‘display amount_2’ else ‘display Amount_1’ end if?>

How to remove space below text?

In the screenshot below, how to remove space below text? I simply added a text box using the type tool and I get that extra space bellow the letter "B" that I don't need. I want to remove that space to center the letter within the octogon.
Thanks!

You might consider giving the letter a negative baseline shift and aligning it to centre.
That way you can adjust it so that its anchor point coincides with the centre of the hexagon.
Like this:
Another thing: You may find it easier working with type if you hide bounding boxes.

How do I remove space after paragraph?

Does Robohelp have the "Remove Space after paragraph" button for reducing the space between lines, like the one in Word?

In HTML the space after is controlled by the style in your CSS file. You need to edit the style in the Style Editor.

There are many more but this is enough to show you. I need to remove all spaces from the First and Third Columns. I need to remove all (--) from the fourth. Where do I put in the substitute function and what is source sting, existing-string, new-string, and occurrence.
Thank You for your help.

How do I remove spaces and special characters from the file name during rendering?

I understand that I can set LR_renamingTokensOn to true, but I would like to replace all spaces in the file name with an underscore and remove characters not in the range A-Z and 0-9. What's the easiest way to achieve this?

local photo = catalog:getTargetPhoto()
local sesn = LrExportSession {
    photosToExport = { photo },
    exportSettings = {
        -- ... (determine from export preset) - whatev you want, just be sure you set export directory: LR_export_destinationPathPrefix
        LR_tokens = "{{custom_token}}",
        LR_tokenCustomString = LrPathUtils.removeExtension( photo:getFormattedMetadata( 'fileName' ) ):gsub( "[ %c]", "" ) -- remove spaces and control characters
sesn:doExportOnNewTask()

How to remove space from a variable in a smartform

Hi,
I have a problem in displaying a variable in a smartform..The variable shows some blank space that preceeds the data.
for eg:,
variable = 18.000.
How to remove space before 18.000?

To remove the decimal places for quantity and rate/quantity , use the syntax to restrict the number of digits after decimal places. The syntax is
&symbol(.N)&
where N is number of decimal places.
Since you dont want decimals use &symbol(.0)&
For the other case it depends on how the currency is represented , any way try using the syntex &symbol(T)&
Please give me reward point If it is useful
Thanks
