Java如何在JDOM中获取XML属性作为整数值？
在此示例中，您可以看到如何将xml属性值读取为整数值而不是字符串。JDOM提供了方法，例如getIntValue()，getLongValue()，getFloatValue()，getDoubleValue()以获得数值。对于布尔值，我们可以使用getBooleanValue()方法。
package org.nhooo.example.jdom;
import org.jdom2.Document;
import org.jdom2.Element;
import org.jdom2.JDOMException;
import org.jdom2.input.SAXBuilder;
import java.io.IOException;
import java.io.StringReader;
public class JDOMIntegerAttributeValue {
public static void main(String[] args) {
String xml = "<root><table width=\"100\"/></root>";
SAXBuilder builder = new SAXBuilder();
try {
Document document = builder.build(new StringReader(xml));
Element child = document.getRootElement().getChild("table");
int tableWidth = child.getAttribute("width").getIntValue();
System.out.println("tableWidth = " + tableWidth);
} catch (JDOMException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
