Package goq was built to allow users to declaratively unmarshal HTML into go structs using struct tags composed of css selectors. I've made a best effort to behave very similarly to JSON and XML decoding as well as exposing as much information as possible in the event of an error to help you debug your Unmarshaling issues. When creating struct types to be unmarshaled into, the following general rules apply: - Any type that implements the Unmarshaler interface will be passed a slice of *html.Node so that manual unmarshaling may be done. This takes the highest precedence. - Any struct fields may be annotated with goquery metadata, which takes the form of an element selector followed by arbitrary comma-separated "value selectors." - A value selector may be one of `html`, `text`, or `[someAttrName]`. `html` and `text` will result in the methods of the same name being called on the `*goquery.Selection` to obtain the value. `[someAttrName]` will result in `*goquery.Selection.Attr("someAttrName")` being called for the value. - A primitive value type will default to the text value of the resulting nodes if no value selector is given. - At least one value selector is required for maps, to determine the map key. The key type must follow both the rules applicable to go map indexing, as well as these unmarshaling rules. The value of each key will be unmarshaled in the same way the element value is unmarshaled. - For maps, keys will be retreived from the *same level* of the DOM. The key selector may be arbitrarily nested, though. The first level of children with any number of matching elements will be used, though. - For maps, any values *must* be nested *below* the level of the key selector. Parents or siblings of the element matched by the key selector will not be considered. - Once used, a "value selector" will be shifted off of the comma-separated list. This allows you to nest arbitrary levels of value selectors. For example, the type `[]map[string][]string` would require one selector for the map key, and take an optional second selector for the values of the string slice. - Any struct type encountered in nested types (e.g. map[string]SomeStruct) will override any remaining "value selectors" that had not been used. For example, given: `[foo]` will be used to determine the string map key,but `[bar]` and `[baz]` will be ignored, with the `[bang]` tag present S struct type taking precedence.
