What is it?

Pretty XML is a XML formatter extension for Visual Studio Code and VSCodium. It formats XML documents just like Visual Studio on Windows.

Supported file extensions:

• xml • xaml • axml • xsd • xsl • plist • mobileconfig • config • csproj • svg • resx and all other XML type of files.

There is also Visual Studio for Mac version of this extension. Check it out at PrettyXML.VSMac

Suggestions, improvement PRs are welcome.

Features

1. Prettify XML (XML Formatting)

Right Click and Select Prettify XML or use shortcut

• Position each attribute on a separate line. • First attribute on same line as start element start tag. • All attributes indented aligning with first attribute. • If no child for an element then close inline end tag. • No empty lines. • Supports ' and whitespace unicodes in attribute value for XAML parser compatibility.

1.a. Format Entire Document

• Lets you format entire valid XML document.

1.b. Format Selection - Beta

• Lets you format part of an XML document. XML can be partial and invalid. This is in beta, so feel free to submit pull request with improvements. • The selection is indented from the indentation of its first line, so it keeps the depth it sits at in the document, and that first line's indentation is kept exactly as it was written. • Indentation follows the editor: one tab per level when the editor inserts tabs, otherwise prettyxml.settings.indentSpaceLength spaces. Continuation lines of a wrapped attribute list line up with spaces, since a column inside a tag cannot be written in tabs. • Nothing is added or removed. An end tag closes the element it names, an element the selection leaves open keeps its content indented under it, and a selection that starts or ends in the middle of a tag keeps those characters as they are. • Content of an element carrying xml:space="preserve" is left as written when that element is inside the selection. • An element whose content mixes text and markup is kept on one line when it begins and ends with text, as in some bold text

. Otherwise the markup that the text joins together shares a line, as in . Text spanning several lines is re-indented a line at a time.
