How to get a value from an XML using XPath in Go

Question

Looking at go xml package I could not find such possibility. Go only allows to define tree of structures, map them to XML tree and deserialize using xml.NewDecoder(myXmlString).Decode(myStruct).

Even if I define needed tree of Go structures, I still can't query that tree using XPath.

C# has convenient function SelectSingleNode that allows to select value from XML tree by specifying XPath without duplicating whole tree structure in C# classes.

Is there similar possibility in Go ? If not then what is simplest way to implement it (possibly reusing xml package) ?

Answer 1

There's also the xmlpath package.

Sample usage:

path := xmlpath.MustCompile("/library/book/isbn") root, err := xmlpath.Parse(file) if err != nil {     log.Fatal(err) } if value, ok := path.String(root); ok {     fmt.Println("Found:", value) }
