wget is a great tool to make a quick snapshot of a small site. As far as I know (I really hope I just couldn't find it in wget --help), wget can follow well-known HTML URL attributes only, like <a href=..., <img src=... and so on. However, sometimes a particular site might use non-standard attributes that represent real URLs that do not look like URLs for wget. Let' say, if a site has a static gallery with zoomed images, a particular image page might have something like this:<div zoomed_img=/gallery/image.jpg>    <img src=/gallery/image_small.jpg/></div>Thus, wget ignores the zoomed_img attribute with /gallery/image.jpg. My wget command is:wget --recursive \    --domains domain \    --no-parent \    --page-requisites \    --no-clobber \    --html-extension \    --convert-links \    http://domain/galleryIs it possible to make wget follow custom URL HTML attributes?
wget: Follow custom URL attributes
wget
wget (at least 1.16.3) does not allow a user to specify custom attributes. There has been a suggestion to extend the the --follow-tags option with a syntax like --follow-tags=a/href, but nobody followed up on that.If you do not mind applying a quick hack to wget to support your scenario, see this commit for the work needed to add custom tags or attributes.Alternatively, you can write a post-processor yourself.
