本文介绍了Expat库的基本概念，它是一种基于事件的XML解析器，类似于SAX但不完全兼容。程序通过注册处理器函数来处理XML解析事件。此外，文章详细讲述了如何在Linux环境下对Expat库进行交叉编译，步骤包括下载源码、配置和安装。

1、expat库简介

refer to wiki:

To use the Expat library, programs first register handler functions with Expat. When Expat parses an XML document, it calls the registered handlers as it finds relevant tokens in the input stream. These tokens and their associated handler calls are called events. Typically, programs register handler functions for XML element start or stop events and character events. Expat provides for more sophisticated event handling such as XML Namespace declarations, processing instructions and DTD events.

Expat is parsing events resemble the events defined in the Simple API for XML (SAX), but Expat is not a SAX-compliant parser. Projects incorporating the Expat library often build SAX and possibly DOM parsers on top of Expat. While Expat is mainly a stream-based (push) parser, it supports stopping and restarting parsing at arbitrary times, thus making the implementation of a pull parser relatively easy as well.
