Keterangan

Metode ini adalah ekstensi Microsoft untuk Model Objek Dokumen (DOM). Ini digunakan ketika Anda ingin memformat dokumen Anda secara manual.

Meskipun metode ini membuat objek baru dalam konteks dokumen, metode ini tidak secara otomatis menambahkan objek baru ke pohon dokumen. Untuk menambahkan objek baru, Anda harus secara eksplisit memanggil salah satu metode sisipan simpul.
