What steps will reproduce the problem?
Build and run the following code:
package main
import "xml"
import "strings"
import "fmt"
import "os"
func main() {
fragment := `<test><![CDATA[ &val=foo ]]></test>`
parser := xml.NewParser(strings.NewReader(fragment))
var err os.Error
for {
if _, err = parser.Token(); err != nil {
if err == os.EOF {
return
}
fmt.Fprintf(os.Stderr, "Xml Error: %s\n", err)
return
}
}
}

Please provide any additional information below.
The XML parser in the Go xml package should ignore special tokens like & and < or
> when they are inside a <![CDATA[ ... ]]> tag.
The current implementation does not and consequently yields parse errors where it should
not.
