Data from html web page in label of AI2

[carto_lover]

is it possible to take a value from a webpage online and put a value of it in a label?

for example from this webpage:

Btp-1mz26 4,5%: rendimenti effettivi - Borsa Italiana

i want to take the value inside this tag

103,62

and this value:

+0,06%

and put them in 2 labels/ textbox

but it's not good for me..

i need text after span class="t-text -black-warm-60 -formatPrice">

and before ** /strong>

the js:

window.AppInventor.setWebViewString(document.getElementsByClassName("t-text -black-warm-60 -formatPrice")[0].innerText + "|"+document.getElementsByClassName("t-text -size-lg -cbalanced -percPrice")[0].innerText)

i saw that the name of class change..

if it is with +
window.AppInventor.setWebViewString(document.getElementsByClassName("t-text -black-warm-60 -formatPrice")[0].innerText + "|"+document.getElementsByClassName("t-text -size-lg -cbalanced -percPrice")[0].innerText)

while if it is -
window.AppInventor.setWebViewString(document.getElementsByClassName("t-text -black-warm-60 -formatPrice")[0].innerText + "|"+document.getElementsByClassName("t-text -size-lg -assertive -percPrice")[0].innerText)

and it changes in a day a lot of times

while if i want also to add last update i tryed adding
window.AppInventor.setWebViewString(document.getElementsByClassName("t-text -black-warm-60 -formatPrice")[0].innerText + "|"+document.getElementsByClassName("t-text -size-lg -assertive -percPrice")[0].innerText+ "|"+document.getElementsByClassName("t-text -block -size-xs | -xs")[0].innerText)

and it's ok!

is it possible to split in 3 labels the 3 values at fly? and not add before in 1 label with "|" ?

[Kevinkun]

you can use any special character as seperator, and use split at block to convert the outcome to a list , then pick item from the list.

[carto_lover]

tryed this

[Kevinkun]

select list item from first, not ITXXXXX

[carto_lover]

yes i corrected it with first!! my fault

[carto_lover]

can i do also operations after retrieved data?

for example i have a value in my labe8
and i want to do a subtraction (-) between 2 labels
label 8 - label27 retrieved from html

the values are correct

[carto_lover]

i replaced , with . and works

is there other way to fix? and use the , ?

[Kevinkun]

in app inventor, even in Math world, comma ','is not part of number.

[carto_lover]

in italy we use , for decimal numbers in math!
anyway i will use .
