android xml to file

The jav开发者_JAVA技巧ax.xml.transform package is not included in the Android SDK, so how to write a dom doc to a file?

---

• org.w3c.dom
• org.xml.sax
• android.sax
• org.xmlpull.v1

If you can't decide which to use, note that SAX is the fastest way to work with XML, DOM being the slowest.
