Restrictions of job.getVariableAsString

[thorsten]

Hi there,

what exactly are the restrictions of this function in node.js script expressions?

Given is an XML structure like

Code: Select all

<Job>
  <Meta Key="key1" Value="value1"/>
  <Meta Key="key2" Value="value2"/>
  <Meta Key="key3" Value="value3"/>
</Job>

In legacy scripting

Code: Select all

job.getVariableAsString('[Metadata.Text:Path="//Meta[@Key=\'key2\']/@Value",Dataset="Job",Model="XML"]');

delivers "value2" as expected. Using Switch variables also works fine.

In node.js I get "The Variable Path is Incorrect".

It looks like referencing the attributes doesn't work in node.js.

Is it a bug oder a feature?

Do you have await before job.getVariableAsString ?

Hi Jan,

Do you have await before job.getVariableAsString ?

yes, I did. I just wanted to keep it short here. Other queries are working and like I said: there is a result but it's always "The Variable Path is Incorrect".

It would take too long to explain here but job.getVariableAsString in NodeJS is limited compared to the one in legacy. And one of the things that will not work is the use of a variable that extracts a piece of information from a dataset.

As an alternative the scripting API has an XmlDocument class: https://cdn.enfocus.com/manuals/Develop ... thods.html. There is sample code on that page you can reuse.

The fact that this is part of the scripting API means you can also use this in a script expression.
