示例1: getTitleNode
func getTitleNode(document *h5.Tree) (titleNode string, err error) {
var chain *selector.Chain
if chain, err = selector.Selector("title"); err != nil {
return
}
if matches := chain.Find(document.Top()); len(matches) > 0 {
match := matches[0:1]
titleNode = h5.RenderNodesToString(match)
}
return
}示例2: ExtractReader
// ExtractReader - Acts like Extract but first parses html body from reader.
func (m SelectorsMap) ExtractReader(buffer io.Reader) (res interface{}, err error) {
// If no buffer return error
if buffer == nil {
err = ErrNoBody
return
}
// Parse body
var node *h5.Tree
node, err = h5.New(buffer)
if err != nil {
return
}
// Extract from top node
res = m.Extract(node.Top())
return
}示例3: rewriteBody
func rewriteBody(containerSelector string, dest io.Writer, body string) (err error) {
if containerSelector == "" {
dest.Write([]byte(body))
return
}
var chain *selector.Chain
var document *h5.Tree
if document, err = h5.NewFromString(body); err != nil {
err = fmt.Errorf("invalid html document: %v", err)
return
}
var titleNode string
if titleNode, err = getTitleNode(document); err != nil {
return
}
if chain, err = selector.Selector(containerSelector); err != nil {
err = fmt.Errorf("invalid css: %v", containerSelector)
return
}
if matches := chain.Find(document.Top()); len(matches) > 0 {
match := matches[0:1] // Take only the first match
newBody := h5.RenderNodesToString(h5.Children(match[0]))
fmt.Printf("data: %v", h5.Data(match[0]))
dest.Write([]byte(titleNode))
dest.Write([]byte(newBody))
return
}
err = fmt.Errorf("container not found")
return
}
