Thymeleaf dynamic images in email - use context?
I'm trying to support dynamic templates for emails. It can happen that some user-defined templates contains images. I have list of all images available, however templates are uploaded just with image placeholders like:
<img style="min-width: 100%;" src="images/email_template_header.gif" th:src="'cid:email_template_banner'"/>
Every image needs to be added inline, the problem is to detect, which images were used?
I can parse template myself (as it's HTML, so it should be easy) and extract all placeholders.
But Thymeleaf parses template itself. I've ended up with additional, custom dialect+AbstractAttributeTagProcessor, which parse "img" tag, so has all needed information.
Now the problem is: how to pass information about tag from inside processor to method which call parser? Can I use somehow context?
AbstractAttributeTagProcessor uses ITemplateContext, while during setting email parameters I use org.thymeleaf.context.Context. They doesn't seem to be connected in any way.
I would like to put list of all found image placeholders to the context, so after parsing I would be able to read this list and attach inline only those images.
