示例1: hasTablPluieClass
func hasTablPluieClass(z *html.Tokenizer) bool {
key, val, more := z.TagAttr()
if string(key) == "class" && string(val) == "tablPluie" {
return true
}
if more {
return hasTablPluieClass(z)
}
return false
}示例2: traverse_html_tokenizer
func traverse_html_tokenizer(z *html.Tokenizer) {
for {
if z.Next() == html.ErrorToken {
return
}
text_b := z.Text()
tag_name_b, hasAttri := z.TagName()
tag_attr_key_b, tag_attr_value_b, _ := z.TagAttr()
text := string(text_b)
tag_name := string(tag_name_b)
tag_attr_key := string(tag_attr_key_b)
tag_attr_value := string(tag_attr_value_b)

}示例3: getAttrVal
func getAttrVal(tokenizer *html.Tokenizer, attrName string) string {
for {
key, val, moreAttr := tokenizer.TagAttr()
if string(key) == attrName {
return string(val)
}
if !moreAttr {
return ""
}
}
}示例4: parseAnchorAttrs
// parseAnchorAttrs iterates over all of the attributes in the current anchor token.
// If a href is found, it adds the link value to the links slice.
// Returns the new link slice.
func parseAnchorAttrs(tokenizer *html.Tokenizer, links []*URL) []*URL {
//TODO: rework this to be cleaner, passing in `links` to be appended to
//isn't great

u, err := ParseURL(strings.TrimSpace(string(val)))
if err == nil {

}
}
if !moreAttr {
return links
}
}
}示例5: getAttrs
/*
* Get list of attributes for a tag.
* If the tag is at the end of a HTML fragment and not all attributes
* can be read by the tokenizer, this call terminates with a "nil"
* map to indicate failure. The tag is than dropped (for an eavesdropper
* this looks like a cached resource)
* @param tk *html.Tokenizer - tokenizer instance
* @return map[string]string - list of attributes
*/
