Functions ¶
func Find ¶
Find a particular node in the tree. The input is a slash-separated list of elements, #names, and .classes to search for. Elements and classes may be combined, such as div#contentName or ul.listClass. A token may also be prefixed with a count N and asterisk (e.g. 2*span), which will find the Nth match.
Example ¶
document := `<html><body><div>
<span>Some text</span>
<span name="abc">ABC</span>
<span class="fancytext">Fancy Text</span>
</div>
</body>
</html>`
root, _ := html.Parse(strings.NewReader(document))
node, _ := Find(root, "html/body/div/#abc")
fmt.Println("Text for #abc is", node.FirstChild.Data)
node, _ = Find(root, "html/body/div/span.fancytext")
fmt.Println("Text for span.fancytext is", node.FirstChild.Data)
node, _ = Find(root, "html/body/div/2*span")
fmt.Println("Text for 2nd span element is", node.FirstChild.Data)
divNode, _ := Find(root, "html/body/div")
node, _ = Find(divNode, "3*span")
fmt.Println("Text for 3rd span element is", node.FirstChild.Data)
Output: Text for #abc is ABC Text for span.fancytext is Fancy Text Text for 2nd span element is ABC Text for 3rd span element is Fancy Text
