如何从元素中提取属性值.我的xml节点是这样写的
< nodename attribute =“value”>我需要将其解压缩以将其与另一个字符串进行比较.
但由于我没有调用document.getElementsByTag,所以我不能使用.getAttribute(“att.”).getNodeValue来获取值.
相反,我有一个NodeList和getAttribute()没有getNodeValue.

factory.setNamespaceAware(true);
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(new File("input.asp.xml"));
document.getDocumentElement().normalize();
NodeList list = document.getElementsByTagName("izdelek");
for(int i = 0; i < 1; i++) {
NodeList child = list.item(i).getChildNodes();
for(int j = 0; j < child.getLength(); j++) {
if(child.item(j).getNodeName().equals("kategorija")) {
category = child.item(j).getTextContent().trim();
} else if(child.item(j).getNodeName().equals("ean")) {
sku = child.item(j).getTextContent().trim();
} else if(child.item(j).getNodeName().equals("izdelekIme")) {
name = child.item(j).getTextContent().trim();
} else if(child.item(j).getNodeName().equals("slikaMala")) {
small_image = child.item(j).getTextContent().trim();
thumbnail = child.item(j).getTextContent().trim();
} else if(child.item(j).getNodeName().equals("slikaVelika")) {
image = child.item(j).getTextContent().trim();
} else if(child.item(j).getNodeName().equals("dodatneLastnosti")) {
NodeList subs = child.item(j).getChildNodes();
// ^ need to parse these nodes they are written as
// i need to print out the value
}
}
//toCSV();
}
} catch(Exception io) {
io.printStackTrace();
}
}
}
解决方法:
解决了：
XML输入：
< nodename attribute="value" > Something nodename>
Java代码：
NodesList subs = child.item(j).getChildNodes();
System.out.println(subs.item(0).getTextContent()); // >> Something
Element element = (Element) document.adoptNode(subs.item(0));
System.out.println(element.getAttribute("attribute")); // >> value
