goxtag
This package is an analog of github.com/andrewstuart/goq for xpath selectors.
Install
go get -u github.com/azlotnikov/goxtag
Example
package main
import (
"github.com/azlotnikov/goxtag"
"log"
"net/http"
)
// Structured representation for github file name table
type example struct {
Title string `xpath:"//h1"`
Files []string `xpath:".//table[contains(concat(' ',normalize-space(@class),' '),' files ')]//tbody//tr[contains(concat(' ',normalize-space(@class),' '),' js-navigation-item ')]//td[contains(concat(' ',normalize-space(@class),' '),' content ')]"`
}
func main() {
res, err := http.Get("https://github.com/azlotnikov/goxtag")
if err != nil {
log.Fatal(err)
}
defer res.Body.Close()
var ex example
err = goxtag.NewDecoder(res.Body).Decode(&ex)
if err != nil {
log.Fatal(err)
}
log.Println(ex.Title, ex.Files)
}

Functions ¶
func Unmarshal ¶
Unmarshal takes a byte slice and a destination pointer to any interface{}, and unmarshals the document into the destination based on the rules above. Any error returned here will likely be of type CannotUnmarshalError, though an initial htmlquery error will pass through directly.
func UnmarshalSelection ¶
Types ¶
type CannotUnmarshalError ¶
type CannotUnmarshalError struct {
Err error
Val string
FldOrIdx interface{}
V reflect.Value
Reason string
XPath string
}
CannotUnmarshalError represents an error returned by the goqxtag Unmarshaler and helps consumers in programmatically diagnosing the cause of their error.
func (*CannotUnmarshalError) Error ¶
func (e *CannotUnmarshalError) Error() string
type Decoder ¶
type Decoder struct {
// contains filtered or unexported fields
}
Decoder implements the same API you will see in encoding/xml and encoding/json except that we do not currently support proper streaming decoding as it is not supported by goquery upstream.
func NewDecoder ¶
NewDecoder returns a new decoder given an io.Reader
