使用标签创建正则表达式？

Question

There are three lines on the pages (000) 000-0-000 and +00 (000) 000-00-00 so I wrote a regular expression that searches for them /([\\+]?[0-9]+\\s)?[\\(][0-9]+[\\)]?[\\s][0-9-]+/ , but the third string is enclosed in tags <strong>(0000)</strong><span>00-00-00</span> how to modify the expression to come across and the third row?

function PhoneReplace(){
            var src = $('body').html().replace(/([\+]?[0-9]+\s)?[\(][0-9]+[\)]?[\s][0-9-]+/g, '098 907 23 42');
            $('body').html(src);

        };

tags can not be deleted, I must be replaced

Answer 1

Don't catch that case in your existing regular expression. Instead, modify the string before you apply your phone number expression, ie remove the tags. There are many ways to do so, eg use a DOM parser, regexes might not be the best tool for that. You could do

var results = input.replace(/<[^>]+>/g,"").match(myPhoneNumberExpression);

to remove all tag-like things.

Answer 2

var s = '<strong>(0000)</strong><span>00-00-00</span>';
var n = '', result;
var regex = /(\+?\d+)/g;
while ((result = regex.exec(s))) { 
  n += result[1];
} 
document.writeln(n);

Answer 3

You can use document.body.innerText or document.body.textContent to get at the textual content (without tags) of the HTML and you can then apply your phone# regular expression.

If the textual content doesn't help, then Strip HTML from Text JavaScript explains several (hacky) ways to remove tags from a string of HTML.
