Changes

• Added support for absolute etree Path queries. An absolute path begins with / or // and begins a search from the element's document root.
• Added GetPath and GetRelativePath functions to the Element type.

Breaking changes

• A path starting with // is now interpreted as an absolute path. Previously, it was interpreted as a relative path starting from the element whose FindElement method was called. To remain compatible with this release, all paths prefixed with // should be prefixed with .// when used with any element other than the document's root.
• [edit 2/1/2019]: Minor releases should not contain breaking changes. Even though this breaking change was very minor, it was a mistake to include it in this minor release. In the future, all breaking changes will be limited to major releases (e.g., version 2.0.0).

The etree package is a lightweight, pure go package that expresses XML in the form of an element tree. Its design was inspired by the Python ElementTree module. Some of the package's features include:

• Represents XML documents as trees of elements for easy traversal.
• Imports, serializes, modifies or creates XML documents from scratch.
• Writes and reads XML to/from files, byte slices, strings and io interfaces.
• Performs simple or complex searches with lightweight XPath-like query APIs.
• Auto-indents XML using spaces or tabs for better readability.
• Implemented in pure go; depends only on standard go libraries.
• Built on top of the go encoding/xml package.

This is the first official release of etree, a go package that has been around for some time but until now has not played well with go vendoring solutions.
