go-xmldom's Introduction

go-xmldom

XML DOM processing for Golang, supports xpath query

Parse XML into dom
Query node using xpath
Update XML using dom

Installation

$ go get github.com/subchen/go-xmldom

Basic Usage

xml := `<testsuite tests="2" failures="0" time="0.009" name="github.com/subchen/go-xmldom">
    <testcase classname="go-xmldom" name="ExampleParseXML" time="0.004"></testcase>
    <testcase classname="go-xmldom" name="ExampleParse" time="0.005"></testcase>
</testsuite>`

doc := xmldom.Must(xmldom.ParseXML(xml))
root := doc.Root

name := root.GetAttributeValue("name")
time := root.GetAttributeValue("time")
fmt.Printf("testsuite: name=%v, time=%v\n", name, time)

for _, node := range root.GetChildren("testcase") {
    name := node.GetAttributeValue("name")
    time := node.GetAttributeValue("time")
    fmt.Printf("testcase: name=%v, time=%v\n", name, time)
}

Xpath Query

// find all children
fmt.Printf("children = %v\n", len(node.Query("//*")))

// find node matched tag name
nodeList := node.Query("//testcase")
for _, c := range nodeList {
    fmt.Printf("%v: name = %v\n", c.Name, c.GetAttributeValue("name"))
}

// find node matched attr name
c := node.QueryOne("//testcase[@name='ExampleParseXML']")
fmt.Printf("%v: name = %v\n", c.Name, c.GetAttributeValue("name"))

Create XML

doc := xmldom.NewDocument("testsuites")

suiteNode := doc.Root.CreateNode("testsuite").SetAttributeValue("name", "github.com/subchen/go-xmldom")
suiteNode.CreateNode("testcase").SetAttributeValue("name", "case 1")
suiteNode.CreateNode("testcase").SetAttributeValue("name", "case 2")

fmt.Println(doc.XML())
