The following constitutes the bare minimum required to replace text in DOCX document.
import (
"github.com/nguyenthenguyen/docx"
)
func main() {
r, err := docx.ReadDocxFile("./template.docx")
if err != nil {
panic(err)
}
docx1 := r.Editable()
// Replace like https://golang.org/pkg/strings/#Replace
docx1.Replace("old_1_1", "new_1_1", -1)
docx1.Replace("old_1_2", "new_1_2", -1)
docx1.ReplaceHeader("out with the old", "in with the new")
docx1.ReplaceFooter("Change This Footer", "new footer")
docx1.WriteToFile("./new_result_1.docx")
docx2 := r.Editable()
docx2.Replace("old_2_1", "new_2_1", -1)
docx2.Replace("old_2_2", "new_2_2", -1)
docx2.WriteToFile("./new_result_2.docx")
r.Close()
}
