INTRODUCTION
Your task is to write a simple Javascript function that extracts certain data from the rows of an HTML table and returns the data as an array of Javascript objects. The function will be executed in a Node.js environment.
This is a very simple project. If you are successful in bidding on this project, and you show yourself to be a professional freelancer, you will be asked to build on your work by completing a number of additional projects for additional pay.
REQUIREMENTS
• Your function will be executed using Node.js v6.11.1.
• Your function must be asynchronous.
• Your function must either (a) accept one argument and return a promise, or (b) accept two arguments, the second of which is a callback function.
INPUT
• Your function will be called with a string containing HTML (less than 30 KB). If necessary, your function will also be passed a callback function in the standard form.
• The HTML will contain a table with two columns, and may contain rows with file numbers structured as described below. Your function should ignore any rows that do not contain file numbers.
• The first cell will contain one or more file numbers of the form /[A-Z]\d+\/\d{4}/ separated by line breaks. It will also contain a URL.
• The second cell will contain one or more file titles separated by line breaks.
EXPECTED OUTPUT
• In this section, when we refer to your function returning a result, we are referring to your function either resolving a promise with the result or executing the callback function with the result, as appropriate.
• Your function must return an array. The array should contain an object for every file number in the HTML table.
• The objects in the array must appear in the same order as the file numbers appear in the table.
• Each object must contain three properties named "number", "title", and "url", corresponding to a file number and URL in the first cell, and a title in the second cell.
• If a row contains more than one file number and more than one title separated by line breaks, the title for each file number should be determined by the line breaks. If a row contains more titles than file numbers, subsequent file numbers in the same row should re-use the title of the previous file number in that row.
• If your function is unable to extract any file numbers, your function must return an empty array.
ASSUMPTIONS
• Like all good developers, you should make as few assumptions about your input as possible.
• If you do make assumptions about your input, for example, by hardcoding observed features of the HTML, you should ensure that it is trivial to update your code in the event that any of those features is changed.
• You can use npm modules, but should do so sparingly.
EXAMPLE 1
Input: '<html></html>'
Output: []
EXAMPLE 2
Input: '<html xmlns="[login to view URL]" xml:lang="en-au" lang="en-au" dir="ltr"><body class="contentpane"><table class="cases"><tbody><tr><td><p><strong>File No.</strong></p></td><td><p><strong>Short Title</strong></p></td></tr><tr><td><a title="Burns" href="/files/file_z186-2017" target="_self">Z186/2017 <br>Z187/2017</a></td><td>Burns & Others </td></tr></tbody></table></body></html>'
Output: [{number: "Z186/2017", title:"Burns & Others", url:"/files/file_z186-2017"}, {number: "Z187/2017", title:"Burns & Others", url:"/files/file_z186-2017"}]

Further examples will be provided to the successful bidder.
