Examples of org.jsoup.nodes.Element.select()

org.jsoup.nodes.Element.select()
Find elements that match the {@link Selector} query, with this element as the starting context. Matched elementsmay include this element, or any of its children.
This method is generally more powerful to use than the DOM-type {@code getElementBy*} methods, becausemultiple filters can be combined, e.g.:
- {@code el.select("a[href]")} - finds links ({@code a} tags with {@code href} attributes)
- {@code el.select("a[href*=example.com]")} - finds links pointing to example.com (loosely)
See the query syntax documentation in {@link org.jsoup.select.Selector}. @param query a {@link Selector} query @return elements that match the query (empty if none match) @see org.jsoup.select.Selector
