Get Data from folder for XML

Hi,

Need help as I got issue with Get Data from Folder feature. The file I'm using are XML. I'm not really understand how XML works, but if I open it in Notepad, there is 1st tag (before Items tag) which is a Date, like this :

So I've done this step :

1. From Power BI Desktop, Get Data, and choose Folder

2. Type the path, and choose Transform Data.

3. In Power Query editor, as the folder contains many other files, I filtered the name to files start with 'xyz' which are my XML files. 

On 1st try, I removed other columns except Content so it become like this :

And press that Combine Files icon on the top right. 

The result is a table of the XML contain but it seems only took data start from Items Tag. 1st question is how to include the 1st tag right before Items tag ?

On 2nd try, I realized before I remove other columns, there is Date Create column, and think I can use that. So leave like this :

And after click Combine Files, the end result still not included that "Date created" column. So, probably my 2nd question is if I want to include that column, which is originally outside the Content, can I and how ? But the 1st questions shoud be fine already.

Thanks in advance.
