类名称：XPathImpl
方法名：eval

XPathImpl.eval介绍

[英]Evaluate an XPath expression in the specified context and return the result as a String.

This method calls #evaluate(String expression,Object item,QName returnType) with a returnType of XPathConstants#STRING.

See "Evaluation of XPath Expressions" of JAXP 1.3 spec for context item evaluation, variable, function and QName resolution and return type conversion.

If a null value is provided for item, an empty document will be used for the context. If expression is null, then a NullPointerException is thrown.
[中]在指定的上下文中计算XPath表达式，并将结果作为String返回。
此方法使用returnType个XPathConstants#字符串调用#evaluate（字符串表达式、对象项、QName返回类型）。
有关上下文项求值、变量、函数和QName解析以及返回类型转换，请参阅JAXP 1.3规范的“XPath表达式求值”。
如果为item提供了null值，则上下文将使用空文档。如果expression是null，则会抛出NullPointerException。
