go - How to compare HTML markup in Golang? -

-

i'm trying come test suite checks html fragments/files canonically equivalent 1 another. surprised see if parse same string or file, https://godoc.org/golang.org/x/net/html#node comparing different. missing?

hopefully demonstrates issue:

package main  import (     "fmt"     "strings"      "golang.org/x/net/html" )  func main() {     s := `<h1>     test     </h1><p>foo</p>`     // s2 := `<h1>test</h1><p>foo</p>`      doc, _ := html.parse(strings.newreader(s))     doc2, _ := html.parse(strings.newreader(s))      if doc == doc2 {         fmt.println("html same") // expected     } else {         fmt.println("html not same") // got     } }

html not same

the simplest way use reflection, since html.parse returns *node object. comparing 2 of objects in go need reflect.deepequal.

if reflect.deepequal(doc, doc2) {                                              fmt.println("html same")  } else {         fmt.println("html not same")                          }

this prints out "html same".

this error has shown on many times, seems. prominent answer issue seems restkit 0.20 — coredata: error: failed call designated initializer on nsmanagedobject class however, solution posted doesn't work me. let's start beginning: i want upload file server. want parse response make sure uploaded. if not, try again later. model has boolean variable called nsnumber *senttoserver purpose (in coredata, bool saved nsnumber ) . because don't know whether sending going successful, save entity coredata model first before sending via restkit. when post request successful, server returns json string this: {"id":14,"created":true} notice that, of course, id not set on coredata model yet, both id , created new informations model. here's model: @interface recording : nsmanagedobject @property (nonatomic, retain) nsstring * audiofilepath; @property (nonatomic, retain) nsdate * createdat; @property (nonatomic, retain) nsstring * deviceid; @
