We recommend an Xml editor (XML Notepad)

Recently, I accidentally found a free Microsoft Xml editor. I think it's good to try it out. I recommend it to you. I don't know if you have a better Xml editor. Microsoft official: http://www.microsoft.com/downloads/details.aspx? Familyid = 72d6aa49-787d-4118-ba5f-4f30fe913628 & displaylang = en.
After the installation, run the program and start the program slowly:

Open the Xml file, which is very convenient to view. You can also directly modify it and save it. Of course, you can also modify the xsd and xsl files.

Microsoft needs to install the SDK directly after downloading it. I pack the installed files, download and unzip them, and run them directly. Download

I will post an official introduction to the functions:

Tree View synchronized with Node Text View for quick editing of node names and values.

Incremental search (Ctrl + I) in both tree and text views, so as you type it navigates to matching nodes.

Infinite undo/redo for all edit operations.

In place popup multi-line editing of large text node values.

Retriable fonts and colors via the options dialog.

Full find/replace dialog with support for regex and XPath.

Intelliisense based on expected elements and attributes and enumerated simple type values.
