RegEx解析自定义标签

Question

I would like to parse following input.

{*HEADER}
Product
{*DESCRIPTION}
Product Name

{*HEADER}
Service
{*DESCRIPTION}
Service Name

and the output should be something like .

List<Dictionary <string,string> >
key = HEADER , value = Product
Key = DESCRIPTION , value = Product Name

and same for the next object of list.

Answer 1

My idea of parsing your input would be the use of negated class and capturing groups .

{\*([^}]+)}\s*([^{]*[^\s{])

• [{\\*([^}]+)} will capture the key to $1
• \\s* followed by any amount of whitespace
• ([^{]*[^\\s{]) captures the value to $2 not ending in a whitespace (right trimmed).
