Question

我有几个配置文件可能有也可能没有某些属性。

例如：

Property1 : value1
Property2 : value2
.
junk text
junk text : line count between useful data varies in every file.
junk text
.
Property3 : value3 //optional

有没有办法只按标签标识符检索属性，并跳过它们之间的所有垃圾？

到目前为止，我无法弄清楚如何跳过垃圾。只有在“记录序列”

之后才允许“忽略”

Answer 1

是的，类似下面的内容，您可以告诉它查找某些标签，并且没有标签的记录可以使用您不感兴趣的标签。
