Modifying HTML in Go should be simple.
🧘🏻 Human friendly: query language for humans that takes a minute to grasp.
🎓 Simplicity: no robust solution here just one single goal
🏎 Fast: has support for zero allocation Set/Append
package main
import "github.com/asaf-shitrit/go-rewrite"
func main(){
example := `
<html>
<body>
<h1 id="content">Hello !</h1>
</body>
</html>
`
// load
doc := html_overwrite.Load(strings.NewReader(example))
// mutate
doc.Set("id=content", "Bye Bye")
// get back
newStringDoc := doc.String()
}import "github.com/asaf-shitrit/go-rewrite"
func main(){
// example stream
res, err := http.DefaultClient.Get("somesite.com")
output := &bytes.Buffer{}
// append
html_overwrite.Append(res.Body, output, "tag=head", injectedValue)
}
The two html identifiers supported right now are:
- id
- class name
// All matchers are split up by a comma (,)
// Pattern: [matcher]=[value],[matcher]=[value]
// Example (By ID): id=content
// Example (By Class): class=great-name
// Example (Multiple Matchers) id=content,class=great-name
Useful for stream cases where a single performant mutation is required.
