I hd gotten a great answer from one of the Power Users here and it seemed to work, now it doesn't.

It should return the X5.234

I dont know what was the reason for the regex that you used.
The \b in front of the X means word boundary - so I do not know how it worked in cases where there was anything but space in front og the X.

This below example pulls out the X value from all of your examples:

Thank you for your answer. I will try that today. As well as my next project is to teach myself those damn regex codes.

I was given that line as a answer to a call for help. I thikn I did nopt explain myself well enough to to original person.

Thank you again for your time.

When I use this code in my program it returns blanks. In test scripts it seems to work fine.

the problem seems to be that sometimes LastLine will have a negative number and sometimes a positive.

LastLine=G1-X1.234
LastLine=G1x1.234

[Icarus]

I dont understand - do you want the minus to be included in the capture?
If so , use this
RegExMatch(PullBack, "(-?[Xx]\d+\.\d+)", PullBackNumber)

[StreetRider]

Here is the problem.

I need to use the number else where as both a positive and a negative.

It seems that if the "Haystack" has the "-" then it returned no string. If it was a postitive number it returns just fine.

If it returns a whole number I can add the "-".

Basically I need to extract jut the number not the "-" as well.

It seems like the other RegEx line I was given does not like the "-".

I do not know what is the other regex you are referring to. If you talk about the regex I provided, then it seems to work just fine, with or without a minus in the string.

The below code demonstrates how both the sample strings that you have provided are captured:

[StreetRider]

Thank you for all of your help.


I think your last attempt did it.

possible varible strings are as follows.

G01X-1.1234
G01X-1.234Y1.123
G01X1.1234
G01X1.1234Y1.1234
X1.234
X-1.1234
X10.1234

These are possible eninding points for a CAD-CAM created CNC file. I need to parse the file replacing G and M-Codes. This I have worked out.But, at the end of the program I need to find the Last X move and re-insert it into the program in two other places.

All the other parts I have figured out, and it works nicely. And faster than I had hoped. Once I have this little problem worked out I can complete this and move onto bigger and better things....

Like learning to understand RegEx... <g>

Thank you again.

Yes, judging by your examples, you need the second regex.

[StreetRider]

thak you for explaining th RexEx line. That is the first time I have seen someone take the time, that makes sense.

I could use a IFInString to send the variable to the right RegEx line. or a If contains....


If var contains -
RegEx
ELSE
RegEx

No need for any IFs. The regex I used is good for both negative and positive values.
Furthermore, if you want the sign to be a part of the captured number, just use this regex:
TheRegEx := "[Xx](-?\d+\.\d+)"

All of your examples will work with this regex, and the captured result ("Result1") will contain the number, and its sign.

EDIT:
Then, if you want to do different things if the value is negative or positive, just ask "If( Result1 > 0 )"
From this point on, treat it as a number.

[StreetRider]

Thakn you for taking the time for this. I need to learn RegEx. For this type of thing it is so much quicker.
