从我所研究的版本来看，XML4C与Xerces - C+ +相比突出的好处是，它的默认安装对大量国际字符编码提供了更好的支持(见参考资料)。
XML4C's distinguishing merit relative to Xerces-C + + is better out-of-the-box support for a huge number of international character encodings in the version that I explored (see Resources).
较理想的做法是，字符串有一个如error或与之相似的子串(见蓝色粗体的语句)，这个子串允许测试者很快地在输出文件中查找到错误。
Ideally, the string of characters should have a substring such as error or something similar (see the statement in bold blue), which will allow the tester to quickly find the error in the output file.
这个页面（见图1）尽可能地简单：您只需一个文本框用于输入字符串，并为每个服务提供一个按钮。
The page (see Figure 1) is as simple as it gets: You just need a text box for the string and a button for each service.
为了保持连续性，先回顾一下本系列第1部分中讨论过的字符串类(见清单2)。
For the sake of continuity, recall the poorly designed string class discussed in part 1 of this series (see Listing 2).
在这个示例中，希望请求一个代表知识库的xml字符串，然后使用这个字符串创建一个XML对象，见清单10。
In this case, you want to request the XML string that represents the knowledge base, and then use that string to create an XML object, as in Listing 10.
为此，您可以在服务器端随机生成字符串，或根据用户输入的数据创建该值(见清单2)。
To do that, you can randomly generate something on the server side, or you can create a value based on the data the user enters (see Listing 2).
要想创建对于所有字符串比较不区分大小写的数据库，需要使用排序规则UCA500R1，见清单4。
To create a database that is case-insensitive for all string comparisons, it is necessary to use the collation UCA500R1 as shown in Listing 4.
每个GET调用返回一个json格式的字符串，这是查询的交易的状态数据，见清单5。
Each GET invocation returns a JSON-formatted data representation of the status of the transaction being queried, as shown in Listing 5.
如果启用了它的话，主题引擎将把这个文本字符串作为变量（$mission）传递给页面模板（见清单1）。
The theme engine will then deliver this string of text, if enabled, as a variable ($mission) to the page template (described in Listing 1).
我高兴地看到Xerces开发者Tinnyng将它添加到了xmlstring类中，并更进一步设字符串指针为null(见参考资料)。
I was pleased to see that Xerces developer Tinny ng added this to the XMLString class and went a step further to null the string pointer (see Resources).
之后，getFormData()会返回包含表单编码数据的字符串（见清单4）。
Then getFormData() returns the string containing the form's encoded data (see Listing 4)
使用窗口边框的宽度和高度以确保插字符在高分辨率显示中能够看得见。

注意：如果数组包含字符型键，那么将保留这些键。（见案例4）
Note: If the array have string keys, the returned array will allways preserve the keys. (See example 4)
