XML解析(DOM) 1. 开始解析某个元素,会遍历整个XML,识别元素节点名称 - (void)parser:didStartElement:namespaceURI:qualifiedName:attributes: 2. 文本节点,得到文本节点里存储的信息数据,对于大数据可能会接收多次!为了节
In this section, we will see some behavioraldifferences between DOM and SAX parser. These differences will help you to choose DOM over SAX or vice-versa based upon the size ofXML filesand the availability of heap memory inJVM. 1. Working The first and major difference between DOM vs SAX pa...

XML Parsing in Android using DOM Parser AndroidDOM(Document Object Model)解析器是一个解析 XML 文档并从中提取所需信息的程序。此解析器使用基于对象的方法来创建和解析 XML 文件。通常,DOM 解析器将 XML 文件加载到 Android 内存中以解析 XML 文档。这会导致更多的内存消耗。该文档通过 XML 文件中的每个可能...

类似于 xml 中的 DOM,这种方式会在内存中构建整个文档的结构,在处理大文件时容易出现 OOM。然而,大部分场景我们并不需要随机地去访问 excel 中的节点。 POI 提供的 SAX 解析可以解决第一个问题,但是 API 太过复杂。为了解决第一个问题,POI 提供了基于事件驱动的 SAX 方式,这种方式内存占用小、效率高, 但是 ...
