how delete the special rows of array string

[marii]

how i can delete  string's rows that have &&KK, in this array?

[Oligarlicky]

1. Wire string data into a for loop
2. Use Match pattern inside the array to detect &&KK and use conditional indexing to output just the elements that don't have &KK

[marii]

plz more explain, i want to delete the rows including &&kk,

What don't you understand?  You were told exactly what to do.  What have you tried?

You use a FOR loop to go through each element of your array.  Use Match Pattern to do the check for &&kk in the string.  If it was not found autoindex that value out.  The conditional indexing is very useful here.

i try it, but it dont work

Post your code. It will help us help you.

In what way is it not working?

Also please next time don't attach a 6MB VI containing a sample array with almost 100k elements. A sample array with 20 elements would be sufficient to show the problem.

He posted in LabVIEW 6.1, which does not have any conditional indexing.

Still there are plenty of threads here that show how to filter a 1D array ... 😉

Good observation on the 6.1. I guess marii will have to

• Create a shift register with an empty array of strings.
• Go through each element in String Data and  search for &&KK using match pattern
• Use a case structure to either append the String Data element to the shift register or leave the shift register as is.
• Create an indicator from the output of the loop's shift register

Whew, I guess I know why NI added the conditional tunnels.

I did notice that after I made that post.  That will indeed make things more interesting.

OpenG has some good examples of how to filter an array.
