svgparser
Library for parsing and manipulating SVG files.
Installation
go get github.com/catiepg/svgparser
Features
Checks if the SVG input is valid according to the W3C Recommendation.
Provides capability to search for SVG elements by id or element name.
Parsing the 'd' attribute of a path element into a structure containing all subpaths with their commands and parameters.
Parsing the value of a style element.
Example
func ExampleParse() {
svg := `
<svg width="100" height="100">
<circle cx="50" cy="50" r="40" fill="red" />
</svg>
`
reader := strings.NewReader(svg)
element, _ := svgparser.Parse(reader, false)
fmt.Printf("SVG width: %s", element.Attributes["width"])
fmt.Printf("Circle fill: %s", element.Children[0].Attributes["fill"])
// Output:
// SVG width: 100
// Circle fill: red
}

Types ¶
type Element ¶
Element is a representation of an SVG element.
func DecodeFirst ¶
DecodeFirst creates the first element from the decoder.
func NewElement ¶
func NewElement(token xml.StartElement) *Element
NewElement creates element from decoder token.
func Parse ¶
Parse creates an Element instance from an SVG input.
Example ¶
package main
import (
"fmt"
"strings"
"github.com/JoshVarga/svgparser"
)
func main() {
svg := `
<svg width="100" height="100">
<circle cx="50" cy="50" r="40" fill="red" />
</svg>
`
reader := strings.NewReader(svg)
element, _ := svgparser.Parse(reader, false)
fmt.Printf("SVG width: %s\n", element.Attributes["width"])
fmt.Printf("Circle fill: %s", element.Children[0].Attributes["fill"])
}
Output: SVG width: 100 Circle fill: red
func (*Element) FindAll ¶
FindAll finds all children with the given name.
Example ¶
package main
import (
"fmt"
"strings"
"github.com/JoshVarga/svgparser"
)
func main() {
svg := `
<svg width="1000" height="600">
<rect fill="#000" width="5" height="3"/>
<rect fill="#444" width="5" height="2" y="1"/>
<rect fill="#888" width="5" height="1" y="2"/>
</svg>
`
reader := strings.NewReader(svg)
element, _ := svgparser.Parse(reader, false)
rectangles := element.FindAll("rect")
fmt.Printf("First child fill: %s\n", rectangles[0].Attributes["fill"])
fmt.Printf("Second child height: %s", rectangles[1].Attributes["height"])
}
Output: First child fill: #000 Second child height: 2
func (*Element) FindID ¶
FindID finds the first child with the specified ID.
Example ¶
package main
import (
"fmt"
"strings"
"github.com/JoshVarga/svgparser"
)
func main() {
svg := `
<svg width="1000" height="600">
<rect id="black" fill="#000" width="5" height="3"/>
<rect id="gray" fill="#888" width="5" height="2" y="1"/>
<rect id="white" fill="#fff" width="5" height="1" y="2"/>
</svg>
`
reader := strings.NewReader(svg)
element, _ := svgparser.Parse(reader, false)
white := element.FindID("white")
fmt.Printf("White rect fill: %s", white.Attributes["fill"])
}
Output: White rect fill: #fff
type ValidationError ¶
type ValidationError struct {
// contains filtered or unexported fields
}
ValidationError contains errors which have occured when parsing svg input.
func (ValidationError) Error ¶
func (err ValidationError) Error() string
