我们还将向您展示如何重用解析器实例。

We will also show you how to reuse parser instances.

youdao

通过这种方式配置解析器可以提高处理属性的速度。

Configuring the parser in this way speeds up the processing of attributes.

youdao

有关格式的知识不在解析器中，而是在模型中，模型可由解析器在运行时直接访问，或者将其生成为解析器可调用的代码。

The knowledge of the format is not in the parser but in the model, which is either accessed directly by the parser at run time, or generated into code that the parser invokes.

youdao

您将告诉解析器何时获取下一个文档片段，而不是在解析器看到文档后告诉您所看到的内容。

Rather than being told what the parser sees when the parser sees it, you tell the parser when to go fetch the next piece of the document.

youdao

解析器的行为更像解释器，而不是编译器。

The parsers behave more like interpreters and are not compilers.

youdao

因此，解析器退出。

So, the parser exits.

youdao

它围绕着文法创建解析器对象。

It creates a parser object around a grammar.

youdao

我们有能力借鉴众多解析器来自行开发用于编译的和一个解析器的内部实现。

We have the ability to translate from a number of parsers to an internal representation which we use for compilation.

youdao

大部分代码都在跟踪解析器的状态。

The bulk of the code tracks the parser state.

youdao

为了达到这个目标，实现了一个插件解析器。

To achieve this, a plug-in parser has to be implemented.

youdao

您可以为这些值使用任何兼容JAXP的解析器。

You can use any JAXP-compliant parser framework for these values.

youdao

假定有一组特性和性质，解析器池应该从内部池中返回一个解析器，如果内部池中没有解析器，那么解析器池应该创建并保存一个新的解析器实例。

Given a set of features and properties, the parser pool should either return a parser from an internal pool or create and store a new parser instance if one does not exist.

youdao

因此为了获得较好的性能，我们强烈建议应用程序只在一个地方创建解析器，然后重用这个解析器实例。

Consequently, in order to achieve better performance, we strongly recommend that your application create a parser once and then reuse this parser instance.

youdao

其中的主要原因在于WPF设计器已经拥有了自己的解析器，而重写该解析器以使用这个公共解析器将要花费大量时间。

A major reason for this is that the WPF designers already have their own parsers and rewriting them to use the common parser will take a significant amount of time.

youdao

首先构造一个解析器。

Start by constructing a parser.

youdao

事实上每个xml解析器都知道它。

Virtually every XML parser inherently knows about it.

youdao

最后，清单6开始解析器循环。

Finally, Listing 6 begins the parser loop.

youdao

用解析器验证枚举列表。

Validate enumerations with the parser.

youdao

由此，所生成的添加到类中的代码不是特定于特定解析器的，或者甚至不是特定于特定的解析器类型。

Because of this, the generated code that gets added to your classes is not specific to a particular parser, or even to a particular type of parser.

youdao

有些工具不使用xml解析器。

Some tools do not use XML parsers.

youdao

它还包括一个rss解析器。

It also includes an RSS parser.

youdao

xml解析器能够处理任何字节流。

An XML parser can process any byte stream.

youdao

和解析器一样，它能生成SAX事件。

Like a parser, it can generate SAX events.

youdao

根据解析器操作说明更改这几行代码。

Change these lines of code according to the parser instruction.

youdao

在使用推方式的情况下，由解析器来控制解析操作，需要向解析器提供要解析的文档和处理程序。

With a push approach, the parser is in control of the parsing operation — you give the parser a document to parse and a handler reference.

youdao

它允许您的应用程序代码从解析器中获取事件，这与SAX解析器自动将事件推入处理程序相反。

It allows your application code to pull or seek events from the parser, as opposed to the SAX parser that automatically pushes events to the handler.

youdao

SQL解析器和XML 解析器在DB2编译器中交互，但是它们预期使用不同代码页的输入。

The SQL parser and the XML parser interact within the DB2 compiler, but they expect their input in different code pages.

youdao

此解析器与以前的xml解析器完全兼容。

This parser is fully compatible with the previous XML parser.

youdao

更复杂的解析器通常都使用这些内置解析器对象创建。

More complex parsers are typically created using these built-in parser objects.

youdao

前面已经提到，解析器回调应用程序以建立数据模型，解析器处于控制地位。

The parser issues callbacks to the application to build the data model, as discussed before, but the parser is in control.
