Not passing much, is use of select over getElementsByClass problematic?

Question about the task

New

Most of my code is similar to the solution code, but I noticed that the solution code tends to search for Element objects matching a class by using the getElementsByClass method, and my code generally uses the select() method (this seems to be more in use currently when searching for how to do this). Also, I tend to select the matching element using first() instead of get(0). It seems that both of these should be equivalent, but I am wondering if the reason it is not passing validation is due to CG strictly looking for the specific methods, or due to something else wrong in my code.

In the HtmlView class, only the getUpdatedFileContents method is still empty. In this task, I'll describe what it should do.

1. In HtmlView, create a protected Document getDocument() throws IOException method that parses the jobPostings.html file using jsoup. The file's encoding is UTF-8. Use the filePath field.

2. Get an element that has the template class.
Make a copy of this object. Then remove the "style" attribute and the "template" class from it.
Use this element as a template to add a new row to the table of job postings.

3. Remove all of the previously added job postings. The only class they have is "vacancy".
There is one existing job posting in the backup.html file: Junior Java Developer.
You need to remove all of the tr tags where class="vacancy".
But don't remove the tr tag where class="vacancy template".
Use the remove method.

4. For each job posting, in a loop:
4.1. Use the clone method to clone the tag template obtained in item 2.
4.2. Get the element that has the "city" class. Write the city from the job posting in it.
4.3. Get the element that has the "companyName" class. Write the company name from the job posting in it.
4.4. Get the hyperlink element (<a> tag). Write the job title in it. Create a working hyperlink to the job posting in place of href="url".
4.5. Add the outerHtml of the element that you wrote job data to, right before the template <tr class="vacancy template" style="display: none">.

5. Return the entire document's HTML code.

6. If an exception occurs, display its stack trace and return "Some exception occurred".

7. Run the application and be sure that all of the job postings are written to the jobPostings.html file.

Requirements:

In the HtmlView class, add a protected Document getDocument() method, in which you will use jsoup to parse the jobPostings.html file.
Implement the getUpdatedFileContents() method. To start, get a parsed page using the getDocument() method.
Get an element that has the template class. Make a copy of this object. Then remove the "style" attribute and the "template" class from it.
Remove from the page all previously added job postings with the "vacancy" class. The element with the "vacancy template" class must remain.
Use the copy of the template to add a separate HTML element to the page before the template object for each job posting. Return the entire page's HTML code.
For each job posting, there should be a valid hyperlink with the job title (title) and URL to the posting (href).
Each job posting must have a valid element with the "city" class.
Each job posting must have a valid element with the "companyName" class.
If an exception occurs, display its stack trace and return "Some exception occurred".
