Trying to extract account status information using a regular expression in the DOM.
Here is the specific string from the page:
<h3>Status</h3><p>Completed</p>Current regular expression being used:
<h3>Status</h3>[\s\S]*?<p>([\s\S]*?)</p>Looking to isolate and capture only the "Completed" status from the string, considering submatching techniques but unsure of implementation.
re.match() will give you the sub-matches for each capture group in an array. Here's how you can use it:
let re = new RegExp('<h3>Status</h3>[\s\S]*?<p>([\s\S]*?)</p>');
let match = re.match(data);
let submatch = match[1];
Here is a regex that will do the job:
/<h3>Status<\/h3>[\s\S]*<[^>]*>([^<]+)<.*/You can test it out on this page: http://jsfiddle.net/M7kJ7/
Although using DOM functions would be more efficient. Why rely on regex when there are better options available?
UPDATE: If direct access to the database is not possible and native DOM functions cannot be used, consider server-side javascript (node.js) or another language like perl with a DOM parser.
For node.js, you can utilize node-htmlparser. Your node app can fetch data from each url, parse it using the parser, and output as json for your page to consume via ajax.
In perl, you can use HTML::DOM for a similar process. Other languages like php, python, or ruby also offer parsing libraries for this purpose.
It's important to handle this logic on the server-side for optimal performance and security.
