方法名：selectObject

Node.selectObject介绍

[英]selectObject evaluates an XPath expression and returns the result as an Object. The object returned can either be a List of one or more Nodeinstances or a scalar object like a Stringor a Numberinstance depending on the XPath expression.
[中]selectObject计算XPath表达式并将结果作为对象返回。返回的对象可以是一个或多个NodeInstance的列表，也可以是标量对象（如Strings）或Numberinstance，具体取决于XPath表达式。
