我有一个看起来像这样的xml:
{ <xml><ep><source type="xml">...</source><source type="text">..</source></ep></xml>}
在这里,我想检索"源类型"的值,其中类型s属性.
我试过这样,但它不起作用:
DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
try {
DocumentBuilder builder = domFactory.newDocumentBuilder();
Document dDoc = builder.parse("D:/workspace1/ereader/src/main/webapp/configurations/config.xml");
System.out.println(dDoc);
XPath xPath = XPathFactory.newInstance().newXPath();
Node node = (Node) xPath.evaluate("//xml/source/@type/text()", dDoc, XPathConstants.NODE);
System.out.println(node);
} catch (Exception e) {
e.printStackTrace();
我也试过这个:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
InputSource is = new InputSource(new StringReader("config.xml"));
Document doc = builder.parse(is);
NodeList nodeList = doc.getElementsByTagName("source");
for (int i = 0; i < nodeList.getLength(); i++) {
Node node = nodeList.item(i);
if (node.hasAttributes()) { …我有一个111行的Excel文件.我需要省略工作表的前两行,然后使用java和POI读取文件.
我的JSP页面中有一个图像.我需要在点击该图像时调用jquery函数.请帮我 !!
JSP页面看起来像,
<html>
<body>
<input type="image" id="closeAuction" value="Close Auction" align="right" src="images/close_auction.png" onclick="return endAuction();" disabled / >
</body>
</html>
我在脚本标记内的jquery函数看起来像,
<script src="JS/jquery-1.3.2.min.js">
$(document).ready(function() {
$('#closeAuction').click(function() {
location.reload();
});
});
</script>
但脚本不起作用!! 任何人都可以帮助调用图像上的功能点击..
