Delete White Space in Strings

[Spencer]

My project involves reading databases of strings and numbers. The
database is not flexible (I can't control what the variable names are
and more importantly, what the spacing is). I am trying to search the
database for certain variable names in a systematic way. Unfortunately
the number and location of blank spaces inconsistent, I would like to
be able to strip the strings of all white space. Is there a built in
function that I can use? Has anyone ever done anything similar? I'm
at a loss here.

For clarity, I'm looking for a way of deleting all the space characters
from my strings.

Look at the VI located at Examples\General\Strings.llb\Search String and
Replace - General.vi

Use it to replace spaces with empty string. The input pattern is a regular
expression so you can enter [\s\t\r\n]+ and it will remove all white
characters, spaces, tabs, returns and line feeds

Take a look also to "Match Pattern" and "Scan String for Token" functions.

Thanks that works great. I appreciate the quick help there.

Seach and Replace string with TRUE on replace all input... it should look like this:

Wow bogdan,

you gave an answer to a 16 years old thread that was already solved…

[bogdan.ciobanu]

Indeed "Knight of NI" ...

but you should stop being sarcastic with that "wow" ... any contribution to the forum should be appreciated and you should know that.

I found this thread searching google ... even if it's 16 years old. I guess other people can do the same and land here with same questions in mind. And for those, I found it more intuitive to have a print screen explaining the sollution than only plain text ... and this is why I added a reply.

Best regards,

Bogdan

I doubt Gerd was attempting sarcasm.  That is usually my input to the forums  True surprise at a 16 year bump to a thread is more likely the intent of "wow"

Trim Whitespace.vi would be a simpler implementation for the OP but, I hope they figured that out over the years.

Except they wanted to remove ALL spaces from the stirng, not just the ends.

First...

Second, resurrecting old threads is generally not necessary especially when they are 15 years, 10 months, 1 week, and 5 days old.  I mean I don't want to date myself too much, but I wasn't in high school when that post was made.  Knights and other LabVIEW celebrities can come across as a bit harsh (myself included) on the forums, but it is partly because we don't need to bring up these old relics, and we want to drive it home to new users, that this generally isn't necessary, especially for topics as simple as this where a single primitive can be used in most cases.
