I was really surprised how easy it was to read an XML document using the encoding/xml package that comes with the standard library. The package works by defining structs that map the XML document. If you need more flexibility then use Gustavo Niemeyer’s xmlpath package (found here).
Here is the XML document we are going to read and de-serialize:
There are two structs, one for the entire document (<straps>) and one for each individual child node (<strap>). If you look closely at the structs you may see something new. Each field has a tag associated with it. These tags are bound to each individual field. Go’s reflect package allows you to access these tags.These tag formats are specific to the decoding support inside the encoding/xml package. The tags map the nodes and attributes of the XML document to the struct.The following code decodes the XML document and returns the array of strap nodes:
We have taught Go to thousands of developers all around the world since 2014. There is no other company that has been doing it longer and our material has proven to help jump start developers 6 to 12 months ahead of their knowledge of Go. We know what knowledge developers need in order to be productive and efficient when writing software in Go.
Our classes are perfect for both experienced and beginning engineers. We start every class from the beginning and get very detailed about the internals, mechanics, specification, guidelines, best practices and design philosophies. We cover a lot about "if performance matters" with a focus on mechanical sympathy, data oriented design, decoupling and writing production software.
