Parsing

[LabRatzz]

Hello,

 

I have these to strings of data how do i use labview to differentiate bettwn the two? the first four letters are always the same and the rest changes,

 

SDFS = Data1

 

ASXP = Data2

 

I guess what i want is when the data comes... labview automaticly knows this line is DATA1 or this line is DATA2

 

 

SDFS~S0000000040942770200002014016980156XXX

 

ASXP`0100361553364651\`

Many ways.  How about getting the string subset on the first four characters and seeing if they equal SDFS or ASXP then getting the string subset of there for the appropriate length and offset for each.

 

I'm sure regular expression could do it too.  Post your VI you have tried and show what you couldn't get to work.

Try the example "Extract Numbers with Match Pattern.vi"

Under the Menu items Help>>Find Examples...

As someone wiser (and more sarcastic) than myself has already pointed out...

 

Some people, when confronted with a problem, think 

“I know, I'll use regular expressions.†  Now they have two problems.

Notice I didn't say to use regular expressions, I just said that it could be used.

Are you checking the data after it was received or while it is being received?  Is there any type of header or pattern to your data?
