Java method for calling XML

The XML format is as follows: <? XML version = "1.0" encoding = "UTF-8"?>
<! -- Cyplate simulator configuration -->
<Cyplate>
<Backgroundchar> ◇ </backgroundchar>
<Foregroundchar> ◆ </foregroundchar>
<Templatewidth> 170 </templatewidth>

1) Get the factory instance of the DOM parser
Documentbuilderfactory domfac = documentbuilderfactory. newinstance ();

2) then get the DOM parser from the DOM Factory
Documentbuilder dombuilder = domfac. newdocumentbuilder ();

3) convert the XML document to be parsed into an input stream so that the DOM parser can parse it
Inputstream is = new fileinputstream ("test1.xml ");

(4) parse the input stream of the XML document to obtain a document

Document Doc = dombuilder. parse (is );

(5) Get the root node of the XML document

Element root = Doc. getdocumentelement ();

(6) obtain the subnode of the node

Nodelist books = root. getchildnodes ();
