TL;DR

Learn how to parse XML documents in Go using the encoding/xml package in this tutorial series.

Key Insights

• 📦 The encoding/xml package in Go simplifies the process of parsing and manipulating XML data.
• 👷 XML documents in Go are defined using structs, with each struct representing an element or attribute in the XML document.
• 👷 Capitalizing values in the XML struct definition is necessary for them to be exported and accessed during unmarshaling.
• 👻 The XML Unmarshal function allows for the conversion of XML data into Go structs.
• ♿ The unmarshaled XML data can be accessed and utilized within the Go program.
• ♿ The tutorial provides additional resources and alternative methods to access XML data if the provided sitemap index cannot be accessed.
• 📜 Looping through the parsed XML data to retrieve specific values from the XML document is discussed in the next tutorial.

Questions & Answers

Q: What is the purpose of the encoding/xml package in Go?

The encoding/xml package in Go allows for the parsing and manipulation of XML data, making it easier to work with XML documents in Go programs.

Q: How do you define the structure of an XML document in Go?

In Go, you define the structure of an XML document using structs. Each struct represents a specific element or attribute in the XML document.

Q: What is the significance of capitalizing values in the XML struct definition?

Capitalizing values in the XML struct definition ensures that those values are exported and accessible when unmarshaling XML data. Lowercase values will not be exported.

Q: How can you parse XML data into Go structs?

To parse XML data into Go structs, you can use the XML Unmarshal function provided by the encoding/xml package. This function takes the XML data and the address of the struct to unmarshal into.
