这里不需要调用一个字符一个字符地进行比较的equals函数，相反，您可以通过引用将解析器报告的名称与字符串常量进行比较。
Instead of making calls to equals which compares strings character by character, you can compare names reported by the parser against string constants by reference.

In this case the ResourceBundle class (see Listing 3) can be used to look up translated string constants and to include the internationalized strings in the XML data.
在使用图8中的Add/Edit对话框构建消息元素目标时，您将Type字段保留为String，以便Value 字段是所希望的字符串常量。
When you constructed the message element target using the Add/Edit dialog in Figure 8, you left the Type field as String so that the Value field could be the desired string constant.
如果您提前知道要进行编码转换的字符串的内容，最好为该字符串创建一个xmlch字符串常量，如清单5所示，而不是调用XMLString：transcode 。
If you know the content of the string to be transcoded ahead of time, then it's better to create an XMLCh string constant for the string, as in Listing 5, instead of calling XMLString: : transcode .
这可以确保在代码中重复使用相同的常量字符串时，可以利用相同的字符串引用。
This ensures that repeated use of the same constant strings in your code will utilize the same string reference.
其他的例子有字符串的地址和常量池入口的内部位置。
Other examples are addresses of strings and the internal locations of constant pool entries.
注意，RSS_URI常量代表默认前缀，因此一个空字符串用作前缀。
Note that the RSS_URI constant represents the default prefix, so an empty string is used as the prefix.
为便于使用，我们定义了一个eventconstants类来声明一些有用的常量，例如主题字符串。
For ease of use, we define a EventConstants class to declare some useful constants such as topic strings.
第二个case表达式在Person的firstName部分使用了一个通配符，但在lastName 部分使用常量字符串Neward 来匹配，在age 部分使用通配符来匹配。
The second case expression uses a wildcard for the firstName part of Person but matches against the constant string Neward in the lastName part and wildcards against the age part.

Evaluate is called with the XPath string passed into the method, the DOM tree you built in the class's constructor, and the constant indicating to return results as a list of nodes.
例如，Python有一个内置的“ % ”操作符，它就执行格式化操作(“ % ”前面的参数就是指定的格式)，因此要确保攻击者不会控制这个格式，也就是说使用常量作为字符串的格式。
For example, Python has a built-in "%" operator that does formatting (the argument before "%" is the format), so make sure the attacker can't control the format, say by making it a constant.
