goxpp
The goxpp library, inspired by Java's XMLPullParser, is a lightweight wrapper for Go's standard XML Decoder, tailored for developers who need fine-grained control over XML parsing. Unlike simple unmarshaling of entire documents, this library excels in scenarios requiring manual navigation and consumption of XML elements. It provides a pull parser approach with convenience methods for effortlessly consuming whole tags, skipping elements, and more, granting a level of flexibility and control beyond what Go's standard XML decode method offers.
Overview
To begin parsing a XML document using goxpp you must pass it an io.Reader object for your document:
file, err := os.Open("path/file.xml")
parser := xpp.NewXMLPullParser(file, false, charset.NewReader)
The goxpp library decodes documents into a series of token objects:
| Token Name |
|---|
| StartDocument |
| EndDocument |
| StartTag |
| EndTag |
| Text |
| Comment |
| ProcessingInstruction |
| Directive |
| IgnorableWhitespace |
You will always start at the StartDocument token and can use the following functions to walk through a document:
| Function Name | Description |
|---|---|
| Next() | Advance to the next Text, StartTag, EndTag, EndDocument token.<br>Note: skips Comment, Directive and ProcessingInstruction |
| NextToken() | Advance to the next token regardless of type. |
| NextText() | Advance to the next Text token. |
| Skip() | Skip the next token. |
| DecodeElement(v interface{}) | Decode an entire element from the current tag into a struct.<br>Note: must be at a StartTag token |
