我有這樣而使用XPath
<Processed>
<address>
<buildingnumber> 29 </buildingnumber>
<street> South Lasalle Street</street>
<city>Chicago</city>
<state>Illinois</state>
<zip>60603</zip>
</address>
<address>
<buildingnumber> 30 </buildingnumber>
<street> West Street</street>
<city>xxx</city>
<state>yyy</state>
<zip>12345</zip>
</address>
</Processed>
一個XML我使用下面的代碼,以打印值解析XML記錄之間如何differentitae
DocumentBuilder builder = tryDom.getDocumentBuilder();
xmlDocument = tryDom.getXmlDocument(builder, file);
factory = XPathFactory.newInstance();
xPath = factory.newXPath();
String expression8 = "//address/descendant-or-self::*[not(*)]";
try {
xPathExpression = xPath.compile(expression8);
Object result = xPathExpression.evaluate(xmlDocument,XPathConstants.NODESET);
printXpathResult(result);
} catch (XPathExpressionException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
public static void printXpathResult(Object result){
NodeList nodes = (NodeList) result;
for (int i = 0; i < nodes.getLength(); i++) {
Node node = nodes.item(i);
String nodeName = node.getNodeName();
String nodeValue = node.getTextContent();
System.out.println(nodeName + " = " + nodeValue);
}
} //end of printXpathResult()
它給我像
輸出buildingnumber = 29
street = South Lasalle Street
city = Chicago
state = Illinois
zip = 60603
buildingnumber = 30
street = West Street
city = xxx
state = yyy
zip = 12345
但問題是我不知道何時一個地址是結束和其他開始。我想要在zip = 60603
之後。我知道第一個地址是結束,其他地址正在啓動。我怎樣才能區分記錄?
感謝
你知道地址節點的數量出現在相關的 –
之前嗎?不是,因爲實時我從網上得到xml,我不知道有多少地址記錄會出現......我希望那每個記錄一些我如何知道新記錄開始... – Basit
我會建議將您的xpaht更改爲「//地址」,並且比迭代結果NodeList的子項(現在是「地址」。 –
