Question

是自动化的新手，我正在使用Selenium和Java。

我有一个问题，我需要通过XML文件找到一个节点并读取该节点中的值。我需要将值与输入字符串进行比较。

有人可以帮我解释如何读取xml文件并从xml中获取值并将其存储在变量中。

<?xml version="1.0"?>
-<cXML timestamp="2017-06-15T18:26:00.271+05:30" payloadID="7500610099-0-PORQ" version="1.2.011">
-<Header>
+<From>
+<To>
+<Sender>
</Header>
-<Request deploymentMode="test">
-<OrderRequest>
+<OrderRequestHeader type="new" orderType="release" orderDate="2017-06-15" orderID="7500610099-0">
+<ItemOut requestedDeliveryDate="2017-06-02" quantity="1" lineNumber="5">
+<ItemOut requestedDeliveryDate="2017-06-02" quantity="1" lineNumber="5">
+<ItemOut requestedDeliveryDate="2017-05-23" quantity="1" lineNumber="1">
+<ItemOut requestedDeliveryDate="2017-05-23" quantity="1" lineNumber="2">
-<ItemOut requestedDeliveryDate="2017-05-23" quantity="9" lineNumber="3">
-<ItemID>
<SupplierPartID>1*VP470</SupplierPartID>
</ItemID>

我需要读取节点<SupplierPartID>

中的值

我们可以使用Java内置库来创建正则表达式模式，并在String中搜索该模式（文件中的数据）。以下代码可能会给你一些想法。

public static void main(String[] args) throws FileNotFoundException 
{
    //Change the path for the file
    String content = new Scanner(new File("/home/santhoshkumar/Desktop/sample.xml")).useDelimiter("\\Z").next();

    //System.out.println(content);

    Pattern pattern = Pattern.compile("<SupplierPartID>(.*)</SupplierPartID>");    
    Matcher matcher = pattern.matcher(content);  

    while (matcher.find()) 
    {    
        System.out.println(matcher.group(1));    

    }    
}

希望这会对你有所帮助。感谢

“下面的代码”就像一个宝石。

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;


DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            DocumentBuilder builder = factory.newDocumentBuilder();                   

          //Parsing of xml is done here
            Document doc = builder.parse(new File("C:\\Users\\User_Name\\Documents\\My Received Files\\PDSL_ABM.xml"));

            //Here we get the root element of XML and print out
            doc.getDocumentElement().normalize();
            System.out.println ("Root element of the doc is " + doc.getDocumentElement().getNodeName());

            NodeList list = doc.getElementsByTagName("SupplierPartID");
            int totalSupplierPartID =list.getLength();
            System.out.println("Total no of SupplierPartID : " + totalSupplierPartID);



          //Traversing all the elements from the list and printing out its data
            for (int i = 0; i < list.getLength(); i++) {

          //Getting one node from the list.
            Node childNode = list.item(i);
            System.out.println("SupplierPartID : " + childNode.getTextContent());
            }
