Hi ahmed,

i have a problem in prasing data

Which problem do you have in parsing the data?

What is the expected result and where do you fail?

Additional note:

How should we help when you only attach images? Attach the VI!

Hi Gred W ,

Hi Ahmed,

when I run your VI with the string constant I get this result:

There are results: You only need to increase the size of the string indicators!

(Switching to a different display mode of those strings might help too.)

thanks for the response but as you can notice in my boucle while i stop when the length of my html text is zero in fact i need to prase data for the 12 Ports but i only get results only for X1 ?

Hi ahmed,

i only get results only for X1 ?

Maybe you need to search for X2, X3, and so on?

Are you sure your search criteria is correct all the time?

Edit:

You are searching for a constant 'id="port label_0"', while this label changes for each item in the HTML table to label_1, label_2m and so on.

Did you even compare your search criterias with the actual HTML text?

Hi GredW ,

Yes exactly that's the problem i was using this other devices to transfer ports informations in which i have the same constant string before port name , any ideas please on how can i extract all ports informations from this html text .

this is my last VI version

Hi Ahmed,

any ideas please on how can i extract all ports informations from this html text .

As already said before: you need to search for incrementing port labels!

Searching for a constant "label_0" will always result in just the first entry found!

Quick fix: search for "port_label_"…

Hi Gred W ,

thanks but in the port indicator i need to display only port name " X1" for example but like that it will display :

0"

        >

X1

also the same problem with link parameters when it's  UP and Down i don't have the same constant string .

Best Regards

Hi Ahmed,

i don't have the same constant string .

As you know what you are looking for you can create your search algorithm accordingly.

(This is much easier than to parse unknown text…)

- You know the generic structure of your HTML text, so you can easily parse single rows of your table.

- In each row you know the number and expected content of each cell.

So create an algorithm to get table rows, then parse each row…
