How to validate XML in Golang 1.20
0In this video we are going to generate source code for the GoLang Program, How to validate XML using chatGPT.
After generating we will verify and run the generated code.
IMPORTANT NOTE on SOURCE CODE: only source code that are acceptable by the youtube description box will be displayed.
In this program I have replaced the angled brackets with > or <. once you copy the source code to editor replace it with greater than or less than symbols respectively.
##############SOURCE CODE#########################
package main
import (
"encoding/xml"
"fmt"
)
func main() {
xmlString := `<person><name>John Doe</name><age>30</age><email>johndoe@example.com</email></person>`
// Parse the XML string
var person struct {
XMLName xml.Name `xml:"person"`
Name string `xml:"name"`
Age int `xml:"age"`
Email string `xml:"email"`
}
err := xml.Unmarshal([]byte(xmlString), &person)
if err != nil {
fmt.Println("Invalid XML string:", err)
return
}
// Print the parsed data
fmt.Println("Parsed data:")
fmt.Println("Name:", person.Name)
fmt.Println("Age:", person.Age)
fmt.Println("Email:", person.Email)
}
##############END OF SOURCE CODE#########################
Below is the explanation for the program:
The program first defines an XML string and assigns it to the xmlString variable. It then uses the xml.Unmarshal() function to parse the XML string into a struct. The struct is defined inline using the struct{} syntax.
The struct fields are tagged with the xml package to specify the XML element names when they are unmarshaled from XML. The XMLName field is used to specify the name of the root element.
If there is an error while parsing the XML string, the program will print an error message and exit.
Finally, the program prints the parsed data using fmt.Println(). This is just an example of what you could do with the parsed XML data. You could modify this program to do whatever you need with the parsed XML data.
