Empty String has a length > 2?



  • So first the code then i explain:

    #PROTOC PARSE "<SOURCE>" LR "Protocol: " "</span>" -> VAR "PROTOC" 
    
    #PROTOCL FUNCTION Length "PROTOC" -> VAR "PROTOCL"
    

    This is the code to parse and get the length of the Protocol string
    I get this back in the Data Box

    PROTOC (Single) = 
    PROTOCL (Single) = 7
    

    Now i am wondering why the length is 7 even though the string is empty...

    So i checked with Replace if i can replace " " with "-" to see if there are 7 spaces but that just gives me this

    PROTOC (Single) = 
    PROTOCL (Single) = PROTOC
    

    What am i doing wrong?

    Thankx

    Maybe it's full of spaces, use the trim block



  • I will check late but thats why i tried to replace " " with "-" but the result was not "-----"


  • Admin

    well it could be tabs as well, or maybe newline characters xD



  • When i use trim i get the Input Variable name as output so its not working
    Now i used a prefix and suffix around the capture and it looks like nothing is in it

    ""
    

    I rly dont know whats the issue here



  • So still dont understand the problem but i find a way around it so thankx anyways
