This data-source enables you to enter the URL of an XML data source, using it to populate the items of a compatible editor, e.g. Data List.
The configuration of the XML data-source has the following options:
The first field is URL, here you can enter either a remote URL, or a local relative file path.
e.g. https://leekelleher.com/umbraco/contentment/data.xml or ~/umbraco/config/lang/en.xml
The next set of fields are the XPath expressions used to populate the data-source's items from the XML data.
Items XPath is to used to populate the item. Name XPath is to select the item's name. Note that this XPath is used within the context of the item, so only needs to be relative to the item' XML node itself, e.g. @name will select the item's name attribute. The same follows for the Value XPath, Icon XPath, and Description XPath fields.
If you need help with XPath expressions and syntax, please refer to this resource: https://developer.mozilla.org/en-US/docs/Web/XPath.
An advanced note about XML namespaces. If your XML data source contains namespaces, these will be automatically loaded in. For default namespaces (without a prefix), these will be prefixed with
nsfollowed by a number, e.g. first will bens1, second will bens2, and so forth.
The value for the XML data-source item is a string.
Depending on the List editor used, this may be wrapped in a List<string>.
