如何使用 Java 替换位于特定标记内的 XML 标记的 CDATA 内的值

我有一个输入XML，如下所示. 通过替换位于"SwapTermList"父标记下的&lt；trade_qty&gt；标记的CDATA内的值，我想从该XML形成一个新的XML字符串.例如<trade_qty><![CDATA[25.0]]></trade_qty>//需要用我要传递的另一个值替换25.0 类似地，也替换位于"TermPriceList"父标记下&lt；FIXED_PRICE&>标记CDATA内的值，而该标记也位于"SwapTermList"父标记下.

<fixed_price><![CDATA[92.053]]></fixed_price>//用我将传递的另一个值替换92.053

示例XML:

我已经从我拥有的现有交易字符串创建了Document对象，并try 了一些代码来获取元素.但坦率地说，我不知道如何才能替换这些值，记住它们是在CDATA中替换的(尽管我不介意替换整个 node ，如trade_qty本身)，而且也只在特定的父 node 下.

private Document parseXML(String xml) throws ParserConfigurationException, SAXException, IOException
    {
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        dbf.setNamespaceAware(true);
        DocumentBuilder db = dbf.newDocumentBuilder();
        Document doc = db.parse(new InputSource(new StringReader(xml)));
        doc.getDocumentElement().normalize();
        return doc;
    }

public void readXML(String tradeResponseXML)
    {
        String replacedXML = "";
        Document doc = null;
        try {
            doc = parseXML(tradeResponseXML);
        }
        catch (ParserConfigurationException | SAXException  | IOException xe)
        {
            logger.error("Error parsing the get response xml: ", xe);
        }

        if(doc != null)
        {
            NodeList nList = doc.getElementsByTagName(SWAP_TERM_LIST_XML_ELEM);
            for (int i = 0; i < nList.getLength(); i++)
            {
                Node nNode = nList.item(i);
                Element eElement = (Element) nNode;
                Element cElement =  (Element) eElement.getElementsByTagName(TRADE_QTY_XML_ELEM).item(0);
                logger.info("Qty : " + cElement.getTextContent());
            }
        }
    }

或以下点网代码的类似功能:

For all node name like Get Trade,
    if (rootnodes.Name == "GetTrade")
    {
        foreach (XmlNode t_node in rootnodes.ChildNodes)
        {
            if (t_node.Name == "TradeHeader")
            {
                foreach (XmlNode s_node in t_node.ChildNodes)
                {
                    if (s_node.Name == "SwapTermList")
                    {

                        foreach (XmlNode p_node in s_node.ChildNodes)
                        {
                            if (p_node.Name == "trade_qty")
                            {
                                ColName = p_node.Name;
                                ColValue = p_node.InnerText;

                                sResponse1 = sResponse1.Replace("<trade_qty><![CDATA[" + Math.Abs(Convert.ToDecimal(ColValue)).ToString() + "]]></trade_qty>", "<trade_qty><![CDATA[" + Math.Abs(Convert.ToDecimal(s.ItemArray.GetValue(4))).ToString() + "]]></trade_qty>");//(It's lots value.)
                            }

                            if (p_node.Name == "TermPriceList")
                            {

                                    {

                                        ColValue = k_node.InnerText;
                                        errorLog.log.LogFile("COlname to update price: " + ColName);
                                        errorLog.log.LogFile("COlValue to update price: " + ColValue);
                                        sResponse1 = sResponse1.Replace("<fixed_price><![CDATA[" + Math.Abs(Convert.ToDecimal(ColValue)).ToString() + "]]></fixed_price>", "<fixed_price><![CDATA[" + Math.Abs(Convert.ToDecimal(s.ItemArray.GetValue(10))).ToString() + "]]></fixed_price>");// its TradePrice value.
                                        errorLog.log.LogFile("Response for fixed price : " + sResponse1);
                                    }
                                }
                            }
                        }
                    }
                }
            }

        }
    }

推荐答案

你可以试着用Jsoup.JSoup实际上是一个html解析器，但也能够解析XML.它非常直观，一旦你熟悉了selector syntax，它就非常容易使用.您可以将CDATA的内容解析为CDataNode，并使用内置方法来获取所需内容.

Maven依赖关系:

<!-- https://mvnrepository.com/artifact/org.jsoup/jsoup -->
<dependency>
    <groupId>org.jsoup</groupId>
    <artifactId>jsoup</artifactId>
    <version>1.16.1</version>
</dependency>

使用JSoup您的代码可以简单地替换这些值，如下所示

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.nio.file.Files;
import java.nio.file.Path;

import org.jsoup.Jsoup;
import org.jsoup.nodes.CDataNode;
import org.jsoup.nodes.Document;
import org.jsoup.parser.Parser;

public class Example {

    public static void main(String[] args) throws IOException {

        InputStream inputStream = new FileInputStream(new File("/path/to/your/test.xml"));
        Document document = Jsoup.parse(inputStream, "UTF-8", "", Parser.xmlParser());

        CDataNode trade_qty = (CDataNode) document.selectFirst("SwapTermList trade_qty").childNode(0);
        CDataNode fixed_price = (CDataNode) document.selectFirst("SwapTermList TermScrList fixed_price").childNode(0);

        System.out.println("original values");

        System.out.println(trade_qty.text());
        System.out.println(fixed_price.text());

        //replace cdata text
        trade_qty.text("5555");
        fixed_price.text("7777");

        System.out.println("replaced values");
        System.out.println(trade_qty.text());
        System.out.println(fixed_price.text());

        //if you want to save the modified document to a new file use below write, else delete the 2 lines below
        document.outputSettings().prettyPrint(false);
        Files.writeString(Path.of("/path/to/your/test_out.xml"), document.outerHtml());
    }
}

Update个

如果我需要替换所有的trade_qty实例，而只需要替换最终价格的一个实例(父"TermPriceList"下的那个)，该怎么办呢？

为了 Select 具有相同标签的多个元素，使用方法select而不是selectFirst.语法相似，不同之处在于它们的返回类型，而SELECT返回Elements，seltFirst返回Element.在您的示例XML中，我没有看到任何具有final_price的标记.但如果有的话，程序与fixed_price是一样的.

如果您想要修改某个元素，您可以为 Select 参数提供几种可能性.例如，第n个子元素、第一个元素、元素x后跟元素y，依此类推.熟悉一下这里的selector syntax号.

我已经复制了前面的示例代码，并根据您的问题在适当的位置修改了它.希望这是不言而喻的.

public static void main(String[] args) throws IOException {

    InputStream inputStream = new FileInputStream(new File("/path/to/your/test.xml"));
    Document document = Jsoup.parse(inputStream, "UTF-8", "", Parser.xmlParser());

    Elements trade_qty_elements = document.select("SwapTermList trade_qty");
    CDataNode fixed_price = (CDataNode) document.selectFirst("SwapTermList TermScrList fixed_price").childNode(0);

    System.out.println("original values of trade_qty_elements");
    trade_qty_elements.forEach(element -> System.out.println(((CDataNode) element.childNode(0)).text()));

    System.out.println("original value of fixed_price");
    System.out.println(fixed_price.text());

    //replace cdata text for example fixed_price with 777 and all trade_qty elements with 999
    fixed_price.text("777");
    trade_qty_elements.forEach(element -> ((CDataNode) element.childNode(0)).text("999"));

    System.out.println("replaced values of trade_qty_elements");
    trade_qty_elements.forEach(element -> System.out.println(((CDataNode) element.childNode(0)).text()));
    System.out.println("replaced value of fixed_price");
    System.out.println(fixed_price.text());

    //if you want to save the modified document to a new file use below write, else delete the 2 lines below
    document.outputSettings().prettyPrint(false);
    Files.writeString(Path.of("/path/to/your/test_out.xml"), document.outerHtml());
}
