Android XML parser for simple xml node strings
提问by mousedown
I need to parse a series of simple XML nodes (String format) as they arrive from a persistent socket connection. Is a custom Android SAX parser really the best way? It seams slightly overkill to do it in this way
我需要解析一系列从持久套接字连接到达的简单 XML 节点（字符串格式）。自定义 Android SAX 解析器真的是最好的方法吗？它接缝略有矫枉过正做在这样
I had naively hoped I could cast the strings to XML then reference the names / attributes with dot syntax or similar.
我天真地希望我可以将字符串转换为 XML，然后使用点语法或类似语法引用名称/属性。

I'd use the DOM Parser. It isn't as efficient as SAX, but if it's a simple XML file that's not too large, it's the easiest way to get up and moving.
我会使用 DOM 解析器。它不如 SAX 高效，但如果它是一个不太大的简单 XML 文件，它是最简单的启动和移动方式。

You might want to take a look at the XPath library. This is a more simple way of parsing xml. It's similar to building SQL queries and regex's.
您可能想查看 XPath 库。这是一种更简单的xml解析方式。它类似于构建 SQL 查询和正则表达式。

I'd go for a SAX Parser:
我会选择 SAX 解析器：
- It's much more efficient in terms of memory, especially for larger files: you don't parse an entire document into objects, instead the parser performs a single uni-directional pass over the document and triggers events as it goes through.
- It's actually surprisingly easy to implement: for instance take a look at Working with XML on Androidby IBM. It's only listings 5 and 6 that are the actual implementation of their SAX parser so it's not a lot of code.
- 它在内存方面效率更高，尤其是对于较大的文件：您不会将整个文档解析为对象，而是解析器对文档执行单向传递并在它通过时触发事件。
- 它实际上非常容易实现：例如查看IBM 的在 Android 上使用 XML。只有清单 5 和清单 6 才是其 SAX 解析器的实际实现，因此代码并不多。

You can try to use Konsume-XML: SAX/STAX/Pull APIs are too low-level and hard to use; DOM requires the XML to fit into memory and is still clunky to use. Konsume-XML is based on Pull and therefore it's extremely efficient, yet the API is higher-level and much easier to use.
您可以尝试使用Konsume-XML：SAX/STAX/Pull API 太低级且难以使用；DOM 要求 XML 适合内存，但使用起来仍然很笨拙。Konsume-XML 基于 Pull，因此非常高效，而且 API 更高级且更易于使用。
