How to usee variable in selectors

Help
1

Hi,

This is my selector:
< webctrl id=‘daily-cal5’ tag=‘TABLE’ />

I would like to change ‘daily-cal5’ in the selector to a variable named updated_daily.

How can I do it?

thanks

@bhe98 you can the replace like this ’ “+variable name+” ’

3

doesn’t work tho.

< webctrl id=’ “+updated_daily+” ’ tag=‘TABLE’ />

4

@bhe98 what error it is showing.

5

object reference not set to an instance of an object

Hi @bhe98

You can use the expression editor to edit the selector. To access it, simple type into the selector expression bar you see in the properties.
Enter this:
“< webctrl id=’” +updated_daily.ToString+ “’ tag=‘TABLE’ />”
and ensure that updated_daily is defined in the scope.

If it fails, please share your .xaml

Cheers

sorry there was a problem uploading my file

I’ve attached a few images

Basically, I am trying to dynamically extract the table from Economic Calendar
But the table changes everyday, and the selector changes according to the day of the week (friday= daily-cal5)

The selector before replacing was < webctrl id=‘daily-cal5’ tag=‘TABLE’ />

Don’t edit it in the selector editor. Copy and paste in the properties tab:
“< webctrl id=’” +updated_daily.ToString+ “’ tag=‘TABLE’ />”

If you want to open the expression editor instead of the selector editor when you click the three dots:
Click on the field beside the selector (not the 3 dots button), type a letter after the string, such as: "< webctrl id=‘daily-cal5’ tag=‘TABLE’ />"a
Click away, now click the three-dots button and it should open the expression editor.

This is the properties tab. Paste the entire string there, do not click the 3-dots button since it opens up the selector editor

Preferably, I need to take a look at your .xaml file
