【Java】Document型をString型から生成する

Posted at

DocumentBuilderクラスやDocumentクラスなどを使うことによってXML形式の文書を操作することができます。
String型をDocument型にパースするためには、InputSource型を使用するようです。

java
String xmlString = "<sample>AAA</Sample>";
InputSource inputSource = new InputSource(new StringReader(xmlString));

InputSourceをインスタンス化します。StringReaderはReaderのサブクラスです。

java
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(inputSource);

※上記のコードでは省略していますが、例外処理が必要になります。
