[英]How to extract value from this XML in JSP
I have an XML as below (has 100s of line): 我有一个XML,如下所示(有100行):
<root>
<data v="1.0">
<cellimage counter="0" cash_filename="C:\Temp\_TempFolder\39d437f08cc302876a70a0f91b137991_h.jpg" width="94" height="141" />
<cellimage counter="1" cash_filename="C:\Temp\_TempFolder\39d437f08cc302876a70a0f91b137991_h.jpg" width="94" height="141" />
</data>
</root>
Can anyone please tell me how I can loop through it and extract attributes like 'counter' and 'cash_filename' from the above XML file in JSP. 任何人都可以告诉我如何遍历它,并从上述JSP中的XML文件提取诸如“ counter”和“ cash_filename”之类的属性。
So far I have following code: 到目前为止,我有以下代码:
<%
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse("http://localhost:8080/data.xml");
NodeList nl = doc.getElementsByTagName("cellimage");
for (int i = 0; i < nl.getLength(); i++) {
//Not sure what to do here!
}
%>
you can get your items quite simple: 您可以很简单地获得商品:
NodeList nl = doc.getElementsByTagName("cellimage");
Element el;
Integer counter;
String fName;
for (int i = 0; i < nl.getLength(); i++) {
//Not sure what to do here!
el = (org.w3c.dom.Element) nl.item(i);
counter = Integer.valueOf(el.getAttribute("counter"));
fName = el.getAttribute("cash_filename");
}
