REGEXP PATTERNS
• attr
Tags: anchored, capturing
Attribute key.
Examples:
Example #1.
".attr" =~ re("DefHash::attr"); # matches
Example #2.
"._attr" =~ re("DefHash::attr"); # matches
Example #3.
".attr1.subattr2" =~ re("DefHash::attr"); # matches
Example #4.
"prop.attr1" =~ re("DefHash::attr"); # matches
Example #5.
"_prop._attr1" =~ re("DefHash::attr"); # matches
Example #6.
"Prop.attr1.subattr2.Subattr3" =~ re("DefHash::attr"); # matches
Example #7.
"_prop.attr1" =~ re("DefHash::attr"); # matches
Cannot start with digit (1).
".0attr" =~ re("DefHash::attr"); # DOESN'T MATCH
Cannot start with digit (2).
"prop.0attr" =~ re("DefHash::attr"); # DOESN'T MATCH
Cannot start with digit (3).
"prop.attr.0subattr" =~ re("DefHash::attr"); # DOESN'T MATCH
Invalid character: dash (1).
".attr-ibute" =~ re("DefHash::attr"); # DOESN'T MATCH
Invalid character: dash (2).
"prop-erty.attribute" =~ re("DefHash::attr"); # DOESN'T MATCH
Invalid character: dash (3).
"prop.attr-ibute" =~ re("DefHash::attr"); # DOESN'T MATCH
Invalid character: whitespace (1).
"property .attr" =~ re("DefHash::attr"); # DOESN'T MATCH
Invalid character: whitespace (2).
"property.attr " =~ re("DefHash::attr"); # DOESN'T MATCH
Invalid character: whitespace (3).
".attr " =~ re("DefHash::attr"); # DOESN'T MATCH
Invalid syntax: dot only.
"." =~ re("DefHash::attr"); # DOESN'T MATCH
Invalid syntax: double dot.
"..attr" =~ re("DefHash::attr"); # DOESN'T MATCH
Invalid syntax: dot without attr.
"attr." =~ re("DefHash::attr"); # DOESN'T MATCH
Invalid syntax: dot without attr (2).
"attr.." =~ re("DefHash::attr"); # DOESN'T MATCH
