PredicateString positioning
Sample element screenshot:
Using PredicateString, the basic positioning method is composed of element attribute name, operator, and target value.
element attribute
comparison operator
==, >=, <=, >, <, !=, <>, can be used to compare values or strings
For example:
label == "SYSTEM (TEXT)"
Logical Operators
AND, OR, NOT, AND are equivalent to &&; OR are equivalent to ||; NOT are equivalent to !
For example:
label == "SYSTEM (TEXT)" AND enabled == true
label == "SYSTEM (TEXT)" OR name == "SYSTEM (TEXT)"
label == "SYSTEM (TEXT)" && NOT enabled != true
Fuzzy match LIKE
Both ? and * can be used as wildcards, ? matches one character, and * matches multiple characters.
For example:
label LIKE "SYSTEM (TEXT)"
label LIKE "?YSTEM (TEXT)"
label LIKE "SYSTEM??TEXT)"
label LIKE "* (TEXT)"
label LIKE "SYSTEM*"
other
BEGINSWITH，ENDSWITH，CONTAINS
例如：
# 匹配属性为 label ，value为 SYSTEM 开头的元素
label BEGINSWITH "SYSTEM"
# 匹配属性为 label ，value为 (TEXT) 结尾的元素
label ENDSWITH "(TEXT)"
# 匹配属性为 label ，value包含 TEXT 结尾的元素
label CONTAINS "TEXT"
