Hi mertzdj ,

 

To replace empty XML tags with null values or empty strings, you can use the Xml.Tables function in combination with the Table.ReplaceValue function.

let
    Source = Xml.Tables(Web.Contents("https://example.com")),
    ReplaceEmptyTables = Table.ReplaceValue(Source, {}, null, Replacer.ReplaceValue, {"Column1", "Column2", "Column3"})
in
    ReplaceEmptyTables

In this example, we first load the XML data using the Xml.Tables function. Then, we use the Table.ReplaceValue function to replace any empty tables in the specified columns with null values. The Replacer.ReplaceValue option tells the function to replace the empty tables with the specified value, which in this case is null. You can also replace empty tables with an empty string by replacing null with "".
