Find and Replace with Visual Studio Code to replace cell alignment with a class - visual-studio-code

Question

Since the align attribute is considered obselete I am cleaning up code to remove it and replace with a CSS class. I'm trying to determine if there is a way to do this using find and replace (or something else) in VS Code.
As an example, I might have some html that looks like this:
<table>
<tr>
<td align="left" class="someclass" id="mainTitleCell" title="Title1">Title1</td>
<td align="center" title="Title2">Title2</td>
<td class="someclass" align="right" title="Title3">Title3</td> <!-- attributes are not always in the same order -->
</tr>
<tr>
<td align="left">Title</td>
<td align="center">Title</td>
<td align="right">Title</td>
</tr>
</table>
which I would like to change to
<table>
<tr>
<td class="left someclass" id="mainTitleCell" title="Title1">Title1</td>
<td class="center" title="Title2">Title2</td>
<td class="right someclass" title="Title3">Title3</td>
</tr>
<tr>
<td class="left">Content</td>
<td class="center">Content</td>
<td class="right">Content</td>
</tr>
</table>
Basically removing the align attribute and either adding a class attribute with a specific value OR adding a specific value to an existing class attribute. Is there a way to do this with the Edit...Replace option in VS Code? I know I can find based on a regex but not sure how I would go about the replace since this becomes
Find the align tag
Remove it
Find a class attribute in the <td> or <th> tag and add the appropriate class
If there is no class attribute, add one with the appropriate class.
Obviously step #1 & 2 are easy, it's #3 & 4 that I'm not sure of. I'd be totally happy with having to run 3 separate find and replace commands (one for left, center and right).
Do I have any options here (I am open to extensions)?
UPDATE:
#Mark had the right answer and I was able to chain together several find and replace commands using the Replace Rules extension. With that I can open a file, run a single keystroke to find and replace everything and clean up the extra spaces in the class attribute.

Try this:
Find: align="(.*?)"(.*?) class="(.*?)"|class="(.*?)"(.*?) align="(.*?)"|align="(.*?)"
Replace: class="$7$1$6 $3$4"$2$5
See regex101 demo.
I'm a little surprised this works as well as it does (I included a couple of other test cases you didn't). The only issue (thus far...) is that it can result in one stray space, as in:
<td class="left ">Title</td> // only happens when there is no class attribute
as you can see in the demo page. You could then search for " and replace with just ". It could be handled by a conditional replacement but vscode find/replace doesn't allow those.
To some degree attributes will be re-ordered so that the class attribute is first, but not always - you didn't mention that as a concern - any attribute that occurs before either the first class or align attribute will not be moved. Otherwise, attributes like id or title if they are between class<->attribute (in any order) will be put last.
