### Install gosax Go Library
Source: https://github.com/orisano/gosax/blob/main/README.md
Instructions on how to install the `gosax` library using Go's package management tool, `go get`. This command fetches the library and its dependencies, making it available for use in Go projects.
```bash
go get github.com/orisano/gosax

### Utilizing xmlb for encoding/xml Compatibility with gosax in Go
Source: https://github.com/orisano/gosax/blob/main/README.md
Demonstrates how to use the `xmlb` extension to simplify rewriting code from `encoding/xml` to `gosax`, providing a higher-performance bridge. It shows the 'before' code using `encoding/xml.Decoder` and the 'after' code using `xmlb.Decoder`, illustrating the change in token type checking and access.
```go
var dec *xml.Decoder
for {
tok, err := dec.Token()
if err == io.EOF {
break
}
switch t := tok.(type) {
case xml.StartElement:
// ...
case xml.CharData:
// ...
case xml.EndElement:
// ...
}
}
```
```go
var dec *xmlb.Decoder
for {
tok, err := dec.Token()
if err == io.EOF {
break
}
switch tok.Type() {
case xmlb.StartElement:
t, _ := tok.StartElement()
// ...
case xmlb.CharData:
t, _ := tok.CharData()
// ...
case xmlb.EndElement:
t := tok.EndElement()
// ...
}
}
```

### Migrating from encoding/xml Token to gosax TokenE in Go
Source: https://github.com/orisano/gosax/blob/main/README.md
Illustrates how to adapt code that uses `encoding/xml.Token` to `gosax.TokenE` for compatibility. This snippet shows the 'before' and 'after' code, highlighting the change in how tokens are retrieved from the XML decoder. Note that `gosax.TokenE` involves memory allocation due to interfaces.
```go
var dec *xml.Decoder
for {
tok, err := dec.Token()
if err == io.EOF {
break
}
// ...
}
```
```go
var dec *gosax.Reader
for {
tok, err := gosax.TokenE(dec.Event())
if err == io.EOF {
break
}
// ...
}
```

### Basic XML SAX Parsing with gosax in Go
Source: https://github.com/orisano/gosax/blob/main/README.md
Demonstrates fundamental usage of the `gosax` library to parse an XML string. It initializes a new `Reader` and iterates through events, printing each event's raw bytes until the end of the file is reached. This showcases the stream-based processing of XML data.
```go
package main
import (
"fmt"
"log"
"strings"
"github.com/orisano/gosax"
)
func main() {
xmlData := `Value`
reader := strings.NewReader(xmlData)
r := gosax.NewReader(reader)
for {
e, err := r.Event()
if err != nil {
log.Fatal(err)
}
if e.Type() == gosax.EventEOF {
break
}
fmt.Println(string(e.Bytes))
}
// Output:
//
//
// Value
//
//
}
```
