类名称：XmlWriter

XmlWriter介绍

[英]Basic XML writer.

This class does not support all XML features. It supports specific features:

• Pretty printing
• Name conversion for elements and attributes.
• Standard ('\n') or platform specific End of line.
• ...
  WARNING: This class does not check full conformity of generated XML.

Pretty printing
Pretty printing may produce unexpected results with mixed content elements.
This implementation true to produce data as soon as possible.
Discovering that an element has a mixed content may happen late, so that indentation behavior changes after such discovery.
If one knows that an element has a mixed content, it is advised to indicate it to the writer by writing an empty string content first in that element.
[中]基本的XML编写器。
此类不支持所有XML功能。它支持特定功能：
*漂亮的印刷品
*元素和属性的名称转换。
*标准（“\n”）或特定于平台的线端。

• ...
  警告：此类不会检查生成的XML的完全一致性。
  漂亮的印刷品
  使用混合内容元素，漂亮的打印可能会产生意想不到的结果。
  这种实现确实能够尽快生成数据。
  发现一个元素有混合内容可能发生得很晚，因此在发现之后缩进行为会发生变化。
  如果知道某个元素包含混合内容，建议首先在该元素中写入空字符串内容，以向编写器指示该内容。
