While it was never difficult, and while the parser is a standard part of the platform, the extra work was a bit of an annoyance.

虽然这并非是一件困难的事情，并且解析器是平台的标准部分，但是额外的工作总是有点让人烦。

Since the grammar of JSON is fairly simple, you can implement such a parser easily without any noticeable performance difference.

由于JSON的语法相当的简单，您可以轻易地实现这种解析器，而不会带来显著的性能差异。

Note that the SAX parser is not required to supply a Locator, but if it does, it must fire this event before any other event.

请注意，不需要SAX语法分析器提供Locator，但是如果它提供了，则必须在任何其它事件之前激活该事件。

You might have to adapt the classpath (second command) if you installed the parser in a different directory.

如果在另一个目录下安装语法分析器，则可能必须修改classpath（第二条命令）。

The MRM CWF parser uses the record's properties (the length of each field) to determine where one Invoice ends and the next one begins.

MRMCWF解析器使用记录的属性（每个字段的长度）来确定一个Invoice记录从何处结束以及下一个Invoice记录从何处开始。

Recognizing and rejecting unexpected formats you aren't prepared to handle is typically the province of a validating XML parser.

识别和拒绝不打算处理的非预期格式通常属于XML验证解析器的范畴。

As you know, SAX parsing requires you to write a ContentHandler that processes parser events.

您知道，SAX语法分析要求您编写处理语法分析器事件的ContentHandler。

Before any provider can be built, the existence of some sort of domain-specific parser is required.
