+# xml文本转换
+
+### 简介
+
+本示例通过XmlSerializer序列化构建xml文本，通过XmlPullParser解析xml文本，通过ConvertXML转化xml文本为JavaScript对象。
+
+### 使用说明
+
+1.点击**Xml 序列化**按钮，会构建xml文本，并在按钮上方的文本框显示xml文本内容。
+
+2.点击**Xml Pull解析**按钮，会解析已经预置的xml文本，并在文本框显示解析信息。
+
+3.点击**Xml 文本转换**按钮，会将预置的xml文本转换为JavaScript对象，并在文本框显示。
+
+### 约束与限制
+
+本示例仅支持在标准系统上运行。
