To obtain all headers in a markdown string using Regex, you can use the following pattern:
/^#+\s(.+)/gm
Explanation of the pattern:
^
matches the start of a line. #+
matches one or more hash symbols (#) that denotes the header level.\s
matches any whitespace character after the hash symbols.(.+)
matches any characters after the whitespace character 1 or more times and captures it. gm
are the flags that indicate to match globally and multiline; g
flag is used to match all instances instead of stopping at the first match, and m
flag is used to match with multiple lines.Using this pattern in JavaScript, you can get all the headers by using the match()
function on the markdown string like this:
const markdownString = "# Header 1\n## Header 2\n### Header 3\n#### Header 4";
const headerPattern = /^#+\s(.+)/gm;
const headers = markdownString.match(headerPattern);
console.log(headers); // Output: ["Header 1", "Header 2", "Header 3", "Header 4"]
This will give you an array of all the headers present in the markdown string.
