I'm trying to write an import/export function for pages that include image files, similar to that for glossary entries.
Do there exist in Moodle functions (or examples) for identifying and extracting filenames from editor content? I am able to use the file libraries to extract the image file details and content and base 64 encode them for export in json format.
I don't really want to search through the editor content string to locate all the plugin files if it's already done somewhere else.
I see that something very similar is done in glossary with xml but I'm having trouble unravelling that code.
Thanks if you can help with any pointers at all.
