Use Special Characters

When there is no keyword before and after a target variable in one line of raw text, that is, the variable is the only string in that line, you can use the character ^ to represent the start of a line and use the character $ to represent the end of a line when defining the line pattern.

Using Special Character for Exact Match

Take the following Paragraph Parser as an example: the parent line only contains a variable of interface name (note that there is space before and after the variable). To define the parent line pattern, you can use “^ $intf $”, which means the variable starts with a space and ends with a space.

Using Special Characters to Avoid Mismatch

Take the following Paragraph Parser as an example. Multiple lines start with the keyword “Area”. To only parse the variable of Area ID, you can use “Area $area_id$” in the ID line pattern, so that only the lines that end with an Area ID will be parsed as ID lines.
