（schema languages）、命名空間（namespaces）、 XPath、XLink、XPointer

業界聯盟已經在XML 之上定義了業界專用的標示語言（markup
languages）以在它們各自的領域中進行資料交換。XML、基於 XML 的標
示語言，以及其他 XML 相關的技術時常用於特定業界中的應用程式間、
跨語言、跨平台的資料交換。
Python 的標準程式庫，出於歷史因素，有多個模組支援 XML，都放在
xml
套件底下，而且功能性有所重疊；本書並沒有涵蓋它們全部，因此，請參
閱線上說明文件（

）。
本書（或更明確地說，本章）只涵蓋 XML 處理中最 Pythonic（Python
式）的做法：
ElementTree
，其優雅性、速度、一般性、多樣的實作，以及
Pythonic 的架構讓它成為 Python XML 應用的首選套件。有關
