How do I replace existing keys/values in an XML document
|
|
This example demonstrates the approaches to replace existing keys/values in an XML document and returns the result within the context of an automated test in execution.
Solution:
Approach 1:
In this example, you store the XML in a variable and using the "xmlReplaceNodesByPaths" command, the path/key pair for an existing path in the document overwrites the existing document value with the new key i.e "income" key is replaced with "salary".
| # | Command | Target | Value |
|---|---|---|---|
| store the xml | |||
| 1 | store | <?xml version="1.0" encoding="UTF-8"?> <insuranceData> <insurance category="valid"> <age>45</age> <income>55000</income> <zipcode>90001</zipcode> <result>You are eligible for a subsidy.</result> </insurance> <insurance category="valid"> <age>64</age> <income>25000</income> <zipcode>14301</zipcode> <result>You are eligible for a subsidy.</result> </insurance> <insurance category="invalid"> <age>15</age> <income>25000</income> <zipcode>08857</zipcode> <result>Combinations of inputs provided out of scope for the calculator.</result> </insurance> </insuranceData> |

Approach 2:
In this example, you store the XML in a variable and using the "xmlReplaceNodesByPaths" command, the path/key pair for an existing path in the document overwrites the existing document value with the new value i.e age value is replaced from "15" to "45".| # | Command | Target | Value |
|---|---|---|---|
| store the xml | |||
| 1 | store | <?xml version="1.0" encoding="UTF-8"?> <insuranceData> <insurance category="valid"> <age>45</age> <income>55000</income> <zipcode>90001</zipcode> <result>You are eligible for a subsidy.</result> </insurance> <insurance category="valid"> <age>64</age> <income>25000</income> <zipcode>14301</zipcode> <result>You are eligible for a subsidy.</result> </insurance> <insurance category="invalid"> <age>15</age> <income>25000</income> <zipcode>08857</zipcode> <result>Combinations of inputs provided out of scope for the calculator.</result> </insurance> </insuranceData> |

Tips, Tricks, Gotchas & Best Practices:
- The XML should be valid and encoded in "UTF-8" format.
- You can use the xmlAssertPathExists command to check if the path is valid or invalid.
The nodeValue should not be greater than existing nodes.
