Constants

const XMLHeader = `<?xml version="1.0" encoding="UTF-8" standalone="yes"?>` + "\n"

XMLHeader is a header that MarshalXML uses to prefix the XML files it creates.

func AddFileFromBytes Uses

func AddFileFromBytes(z *zip.Writer, zipPath string, data []byte) error

AddFileFromBytes takes a byte array and adds it at a given path to a zip file.

func AddFileFromDisk Uses

func AddFileFromDisk(z *zip.Writer, zipPath, diskPath string) error

AddFileFromDisk reads a file from disk and adds it at a given path to a zip file.

func Decode Uses

func Decode(f *zip.File, dest interface{}) error

Decode unmarshals the content of a *zip.File as XML to a given destination.

func ExtractToDiskTmp Uses

func ExtractToDiskTmp(f *zip.File, path string) (string, error)

ExtractToDiskTmp extracts a zip file to a temporary file in a given path, returning the name of the file.

func MarshalXML Uses

func MarshalXML(z *zip.Writer, filename string, v interface{}) error

MarshalXML creates a file inside of a zip and marshals an object as xml, prefixing it with a standard XML header.

func MarshalXMLByType Uses

func MarshalXMLByType(z *zip.Writer, dt unioffice.DocType, typ string, v interface{}) error

func MarshalXMLByTypeIndex Uses

func MarshalXMLByTypeIndex(z *zip.Writer, dt unioffice.DocType, typ string, idx int, v interface{}) error

func RelationsPathFor Uses

func RelationsPathFor(path string) string

RelationsPathFor returns the relations path for a given filename.

type DecodeMap Uses

type DecodeMap struct {
    // contains filtered or unexported fields
}

DecodeMap is used to walk a tree of relationships, decoding files and passing control back to the document.

func (*DecodeMap) AddTarget Uses

func (d *DecodeMap) AddTarget(filePath string, ifc interface{}, sourceFileType string, idx uint32) bool

AddTarget allows documents to register decode targets. Path is a path that will be found in the zip file and ifc is an XML element that the file will be unmarshaled to. filePath is the absolute path to the target, ifc is the object to decode into, sourceFileType is the type of file that the reference was discovered in, and index is the index of the source file type.

func (*DecodeMap) Decode Uses

func (d *DecodeMap) Decode(files []*zip.File) error

Decode loops decoding targets registered with AddTarget and calling th

func (*DecodeMap) IndexFor Uses

func (d *DecodeMap) IndexFor(path string) int

func (*DecodeMap) RecordIndex Uses

func (d *DecodeMap) RecordIndex(path string, idx int)

func (*DecodeMap) SetOnNewRelationshipFunc Uses

func (d *DecodeMap) SetOnNewRelationshipFunc(fn OnNewRelationshipFunc)

SetOnNewRelationshipFunc sets the function to be called when a new relationship has been discovered.

type OnNewRelationshipFunc Uses

type OnNewRelationshipFunc func(decMap *DecodeMap, target, typ string, files []*zip.File, rel *relationships.Relationship, src Target) error

OnNewRelationshipFunc is called when a new relationship has been discovered.

target is a resolved path that takes into account the location of the relationships file source and should be the path in the zip file.

files are passed so non-XML files that can't be handled by AddTarget can be decoded directly (e.g. images)

rel is the actual relationship so its target can be modified if the source target doesn't match where gooxml will write the file (e.g. read in 'xl/worksheets/MyWorksheet.xml' and we'll write out 'xl/worksheets/sheet1.xml')

type SelfClosingWriter Uses

type SelfClosingWriter struct {
    W io.Writer
}

SelfClosingWriter wraps a writer and replaces XML tags of the type <foo></foo> with <foo/>

func (SelfClosingWriter) Write Uses

func (s SelfClosingWriter) Write(b []byte) (int, error)

type Target Uses

type Target struct {
    Path  string
    Typ   string
    Ifc   interface{}
    Index uint32
}
