Android memo, for your own use, do not laugh: (3) XML

Parse XML. Android has two mage types: the SAX method (stream and event, using a relatively large XML, which requires performance) and the DOM method (the entire file is loaded and parsed, provides interface operations, using small XML, without performance requirements ).

 

Code snippet:

SAX:

Import javax. xml. parsers. SAXParserFactory
Import javax. xml. parsers. SAXParser

//

SAXParserFactory factory = SAXParserFactory. newInstance ();
SAXParser parser = factory. newSAXParser ();
ParseXML parX = new ParseXML ();
Parser. parse ("F: \ emps. xml", parX );

 

DOM:

Import javax. xml. parsers. DocumentBuilderFactory
Import javax. xml. parsers. DocumentBuilder
//
DocumentBuilderFactory dbf = DocumentBuilderFactory. newInstance ();
DocumentBuilder db = dbf. newDocumentBuilder ();
Doc = db. parse (docFile); // get the document.

 

I often use DOM. The following example code:

 1 InputStream kana = this. _ activity. getResources (). getAssets (). open (_ fileName );
2 Document doc = DocumentBuilderFactory. newInstance (). newDocumentBuilder (). parse (kana );
3 Element root = doc. getDocumentElement (); // get the root node
4 NodeList lstNodes = root. getElementsByTagName (yin). item (0). getChildNodes ();
5 //
6 for (int I = 0; I <lstNodes. getLength (); I ++)
7 {// because there are still empty nodes, pay attention to the node type before conversion.
8 if (lstNodes. item (I). getNodeType () = Node. ELEMENT_NODE)
9 {
10 Element el = (Element) lstNodes. item (I );
11 KanaXml temp = new KanaXml ();
12 temp. Hiragana = el. getAttribute (_ hiragana );
13 temp. Katakana = el. getAttribute (_ katakana );
14 temp. Romaji = el. getAttribute (_ romaji );
15 temp. Sound = el. getAttribute (_ sound );
16 lstXmls. add (temp );
17}
18}
