String replace on a variable in an automation script

Rees, Ian

Original question below but having done further testing is more fundamental

How can I use variables in the String replacement part e.g.

{{webresponse.body.name.replace("CHG","GHC")}} works

but VarOne=CHG and varTwo=GHC

{{webresponse.body.name.replace("{{varOne}}","{{varTwo}}")}}  gives syntax errors.

How can I use variables in the replace part

 

Is is possible to do a string replacement on a smart variable that I have created in an automation script, using variables as the replacement string e.g.

Create Variable varLongStr

"Here is my number one text"

Create Variable varOne

"one"

Create Variable varTwo

"two"

and I want to modify varLongstr using something like

{{varLongStr}}.replace("{{varOne}}","{{varTwo}}")}}

but I can't get the syntax right

Hi @Rees, Ian 

Short answer, please try this:

{{varSource.replace(varOne, varTwo)}}

Where the variables are defined as this:

• action: create variable
  • name: varSource
  • smart value: Here is my number one text
• action: create variable
  • name: varOne
  • smart value: one
• action: create variable
  • name: varTwo
  • smart value: two

 

For more information...

Some rule functions accept variable parameters and some will not.  And even for those which work standalone, they may not work in other contexts, such as inside of an iterator.  The only way to know for certain is experimentation.

Please also note:

You are using the replace() function, which takes text as parameters.  Note in my example, there are no quotation marks in the variable definitions.  The function call handles that as variables are text value type.  The same is true when storing a regular expression on a variable, such as when using replaceAll() or match(). The key is to escape any reserved characters for the regular expressions.

Kind regards,
