Text Delimited, Regular Expression, JPath, and XPath extractors can have dynamic properties containing not only constant values but also variables. A dynamic property value consists of a combination of constant strings and variables.
The following property can be dynamic:
- text before and text after, in the text delimited extractors
- the regular expression in the regular expression extractors
- JPath query in the Json Jpath Query extractor
- XPath query in the XML Xpath Query extractor
To insert a variable in a dynamic property, use the variable notation described here. The following variable types are supported:
- Extractors
- Datasets
- Data Generators
- Functions
- Scriptable variables
Create dynamic extractor
To create a dynamic extractor, the first step is to set the Is the extractor dynamic? property to Yes.
Then, when setting the extractor definition, you may use variables.
Example:
Imagine the following response:
<input .... name="John" id="11111" />
<input .... name="Laura" id="22222" />
<input .... name="Anita" id="33333" />
You need to extract the id of Laura (22222) because that was the value picked from the dataset. Create the following extractor
Text before: name="{{Contact.FName$Dataset}}" id="
Text after: "
If the value from the dataset on the next iteration would be John, then this extractor would return 11111.
