-**Note:** source with a `tag` option takes precedence over source without.

-For example, to process `data-src` attributes on _all_ tags, omit the tag name:

-**webpack.config.js**

-```js
-module.exports = {

-> ⚠ You **must** specify a tag name if using `...` to extend attributes for tags already in the default sources list
-
-For example, to extend the default source list so that it also processes `data-src` attributes on _all_ tags, you might be tempted to do this:
-
-```js
-module.exports = {
-  module: {
-    rules: [
-      {
-        test: /\.html$/i,
-        loader: "html-loader",
-        options: {
-          sources: {
-            list: [
-              // All default supported tags and attributes
-              "...",
-              {
-                attribute: "data-src",
-                type: "src",
-              },
-            ],
-          },
-        },
-      },
-    ],
-  },
-};

-However this will only process `data-src` attributes on tags that _aren't in the default list_:
-
-- `<p data-src="..">` will be processed, as `p` is not in the default sources list
-- `<img data-src="..">` won't be processed, as `img` is already in the default sources list
-
 > You can use your custom filter to specify html elements to be processed.
