Xml is formatted incorrectly

[lawrencek76]

Issue Type: Bug

select from a table with xml field data saved like

<PersonName><FormattedName>Alfred Jefferson</FormattedName><GivenName>Alfred</GivenName><FamilyName>Jefferson</FamilyName></PersonName>

'''

when clicking on the xml to view it then displays with extra new lines and spaces within the element values actaully changes the data in the elements as follows

``` xml
<PersonName>
	<FormattedName>
		Alfred Jefferson
	</FormattedName>
	<GivenName>
		Alfred
	</GivenName>
	<FamilyName>
		Jefferson
	</FamilyName>
</PersonName>

the proper pretty print for the original xml that does not change the value of the nodes is

<PersonName>
	<FormattedName>Alfred Jefferson</FormattedName>
	<GivenName>Alfred</GivenName>
	<FamilyName>Jefferson</FamilyName>
</PersonName>

In addition to this correct behavior, formatting settings are needed. It’s even better to add some good existing VS Code plugin to the list of supported ones.

Now you can install the plugin from VS Code through the VSIX installation.
For example, download the XML Tool plugin and set it as default formatter after installation.

The viewer corrupts the file content.

Store an XML string to a column, query the table and click on the XML value to open it to the viewer; all the element contents are line breaked and indented.

If you decide to manually do some changes to the data and push it back to the table through an update query (update myTable Set Xml = N'xmlCopyPastedFromTheViewerHere'), all the line breaks become part of the element contents, which they originally were not.

No such problem with the old SSMS.

Unless your file handling trims all the whitespace out of the values, you can expect some interesting UI glitches in your app.
