get_config_elements [name_patterns] [-hierarchical] [-in_wrappers wrapper_object_spec]
[-partition partition] [-count] [-type type] [-filter filter]
[-regexp] [-nocase] [-silent]

假设spec如下：

tmp(1) {
  ABC (Def,2) {
    prop1 : 1;
    Prop2 : 2;
  }
  abc(def,1) {
  }
  abcdef {
  }
 
}

Case 1

This matches the wrappers with leaf name “abc” inside wrapper tmp(1) independent of whether it has an id. The matching is case-insensitive because only the id matching is case-sensitive.

get_config_elements abc -in tmp(1)

{/tmp(1)/ABC(Def,2) /tmp(1)/abc(def,1)}

Case 2

This matches the wrappers with the first id equal to “Def”. Notice that it does not match abc(def,1) as ids are matched considering casing unless the -nocase option is used.

get_config_elements *(Def,*) -in tmp(1)

{/tmp(1)/ABC(Def,2)} get_config_elements *(Def,*) -in tmp(1) -nocase

{/tmp(1)/ABC(Def,2) /tmp(1)/abc(def,1)}

Case 3

This matches elements below the top-level wrapper starting with a*.

get_config_element */a*

{/tmp(1)/ABC(Def,2) /tmp(1)/abc(def,1) /tmp(1)/abcdef}}

Case 4

This matches elements below the top-level wrapper starting with a* and having two ids.

get_config_element */a*(*,*)

{/tmp(1)/ABC(Def,2) /tmp(1)/abc(def,1)}}

Case 5

This matches elements starting with ‘p’ anywhere inside tmp(1).

get_config_element p* -in tmp(1) -hierarchical

{/tmp(1)/ABC(DeF,2)/prop1 /tmp(1)/ABC(DeF,2)/Prop2}

它的这个（）括号是不匹配的，需要显式写出来。
