类名称：Yamls
方法名：getTextOfYamlAtPath

Yamls.getTextOfYamlAtPath介绍

[英]Given a path, where each segment consists of a string (key) or number (element in list), this will find the YAML text for that element

If not found this will return a YamlExtract where YamlExtract#isMatch() is false and YamlExtract#getError() is set.
[中]给定一个路径，其中每个段由字符串（键）或数字（列表中的元素）组成，这将找到该元素的YAML文本
如果未找到，将返回一个YamlExtract，其中YamlExtract#isMatch（）为false，并且设置了YamlExtract#getError（）。
