Unlike Condition, the expression that you specify is not appended to the implicit XPath expression that corresponds to the current element. The following example shows how to select the same elements that are selected by the preceding example for the Condition keyword. Replaces the selected element with the element that is specified in the transform file. If more than one element is selected, only the first selected element is replaced.

For an example of how to use the Replace keyword, see the examples for the Locator attributes. Adds the element that is defined in the transform file as a sibling to the selected element or elements.

This feature substitutes values in the JSON configuration files. It overrides the values in the specified JSON configuration files for example, appsettings. File names must be specified relative to the root folder.

For example, if your package has this structure:. Alternatively, use wildcard patterns to search for specific JSON files.

Files names must be relative to the root folder. You can use wildcards to search for JSON files. To substitute values in nested levels of the file, concatenate the names with a period. A JSON object may contain an array whose values can be referenced by their index. For example, to substitute the first value in the Users array shown above, use the variable name DBAccess. However, the file transform task has the ability to transform entire arrays in JSON files.

You can also use DBAccess. Variable substitution is applied for only the JSON keys predefined in the object hierarchy. It does not create new keys.
