Parsing strings.

[moonrocks]

I have this string as below:
0xABCDEFAB #LADKJF
0XAABBCCDD #ADKF
0XAABBCCDD

How can I strip out everything
except for the hex numbers, ie.:
ABCDEFAB
AABBCCDD
AABBCCDD

I've tried it for the whole afternoon.
But no luck. Can anyone help?

Thanks,
Van

Hmm, "Spreadsheet string to Array" with as separator. Then "Scan
From String" with format string "0%[xX]%x". This will as second
parameter actually return an 32bit integer, representing the value of
the hexadecimal string.

Included image shows two possible ways actually. Watch out to enable "\
code Display" for the string constants.

You came through for me again.
Much appreciated.

I have a simular problem that I have been working on for a couple days. I have a string that looks like this

+7.50000000E+01 F,101,+7.50000000E+01 F,102,+7.50000000E+01 F,103,+7.50000000E+01 VDC,104

I want to search the string for a channel number (i.e. 102 ect.) an parse  the reading (+7.50000000E+01 F) less the (F) convert from fract/exp string to number and place it into a 1D array. I have tied the example "extract numbers.vi" and was able to get all the number out of the string but it did't preserve the exp values i.e. it read 7.5 instead of 75.

I'm greatful for any help,

The attached vi proposes two different solutions. Hope one will fit your needs

That works great. I didn't realize that you could do that so simply. I need to do more programming not just when we need something. Again thanks so much. jb112454

Hi

I'm trying to parse a string and seperate it into 

String

Number

String

The only problem is that the output is not delimited by a special character (, ; : ! - _ or anything of the sort).

An example would be 

B43F

whereas another example would be J

I could also have 102443H

and so on...

The amount of chars is random so is the offset. So basically, is there a function that can scan a string and differrentiate a number from a string.

I've tried the scan function

e.g

B43F

With Scan function and %s I guess, B43F

e.g

43F with Scan function and (double) I get 43 and F. This works!

Thanks again!

Use %[^0-9]%d%s for your format.  The %[^0-9] takes a string up until, but not including, a decimal character.

Thanks.

I'll try that!

I was reading up on those format strings but couldn't quite understnad how to use it.
