// include the latest version of the regex crate in your Cargo.toml
extern crate regex;
use regex::Regex;
fn main() {
let regex = Regex::new(r"(?mi)(?<!&)(?:\b(?:nbsp|quot|divide)|#[0-9a-f]+);").unwrap();
let string = "I have a huge HTML with several special chars, in the forms or \"�.
Faulty HEX: #82173333;
Some of them are wrong, because they lack the initial &.
I would like to search for such wrong spacial chars. I know that I can search all the right special chars by means of the following regex:
\\&(?:[a-z]+|#x?\\d+);\\
But I'd need a regex useful to search the wrong ones (without the initial &). Can you help me? Thanks in advance
Edit:
As suggested, I post an example. My HTML cointains the following statement:
<![CDATA[<nolink>blablabla blablabla</nolink>]]>nbsp;
where we have 2 special HTML character:
divide;
÷
quot;
I'm interested in finding the second item, because it is wrong (laking the initial &).
So the output of the requested regex should be: quot;";
// result will be an iterator over tuples containing the start and end indices for each match in the string
let result = regex.captures_iter(string);
for mat in result {
println!("{:?}", mat);
}
}
