Question

我想将XML文件拆分为单独的XML。通过阅读和标签。我已经使用StringUtils.substringsBetween拆分了XML。但是，我只能从文件中拆分两个XML。第三个XML随第二个XML追加。

程序：

import java.io.BufferedReader;
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;

import org.apache.commons.lang3.StringUtils;

public class SBuff {

    private BufferedReader br;

    public SBuff() {
        // TODO Auto-generated constructor stub
    }

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

         String data = "<?xml version=\"1.0\"?>\r\n" + 
                "<company>\r\n" + 
                "    <staff>\r\n" + 
                "        <firstname>yong</firstname>\r\n" + 
                "        <lastname>mook kim</lastname>\r\n" + 
                "        <nickname>mkyong</nickname>\r\n" + 
                "        <salary>100000</salary>\r\n" + 
                "    </staff>\r\n" + 
                "    <staff>\r\n" + 
                "        <firstname>low</firstname>\r\n" + 
                "        <lastname>yin fong</lastname>\r\n" + 
                "        <nickname>fong fong</nickname>\r\n" + 
                "        <salary>200000</salary>\r\n" + 
                "    </staff>\r\n" + 
                "    <staff>\r\n" + 
                "        <firstname>low</firstname>\r\n" + 
                "        <lastname>yin fong</lastname>\r\n" + 
                "        <nickname>fong fong</nickname>\r\n" + 
                "        <salary>200000</salary>\r\n" + 
                "    </staff>\r\n" + 
                "</company>\r\n"+
                "</xml>";

        SBuff s = new SBuff();
        s.loadData(data);
    }

    public void loadData(String stream) throws IOException {
        String[] list = StringUtils.substringsBetween(stream,
                "<staff">", "</staff>");

        StringBuilder stringBuilder = new StringBuilder();
        for (String s : list) {

            stringBuilder.append("<staff>");
            stringBuilder.append(s);
            stringBuilder.append("</staff>");
            System.out.println("##################################");
            System.out.println(stringBuilder.toString());
            System.out.println("##################################");
        }

    }

    public void display(String data) {
        System.out.println("Buffer Data: " + data);
    }
}

输出：

Expected:

##################################
<staff> 
   <firstname>yong</firstname> 
   <lastname>mook kim</lastname>
   <nickname>mkyong</nickname> 
   <salary>100000</salary>
</staff>
##################################
<staff>
   <firstname>low</firstname> 
   <lastname>yin fong</lastname> 
   <nickname>fong fong</nickname> 
   <salary>200000</salary>
</staff>
##################################
<staff>
   <firstname>low</firstname> 
   <lastname>yin fong</lastname> 
   <nickname>fong fong</nickname> 
   <salary>200000</salary>
</staff>
##################################


Actual:

##################################
<staff> 
   <firstname>yong</firstname> 
   <lastname>mook kim</lastname>
   <nickname>mkyong</nickname> 
   <salary>100000</salary>
</staff>
##################################
<staff>
   <firstname>low</firstname> 
   <lastname>yin fong</lastname> 
   <nickname>fong fong</nickname> 
   <salary>200000</salary>
</staff><staff>
   <firstname>low</firstname> 
   <lastname>yin fong</lastname> 
   <nickname>fong fong</nickname> 
   <salary>200000</salary>
</staff>
##################################

我尝试了不同的方法。似乎没有锻炼。预先感谢。

您可以使用jsoup之类的XML解析器。

<mapping wildcard="false" map-null="false">
    <class-a>XXXX.XXXX.acord_pc_1_22.external.XXXX.NameInfoType</class-a>
    <class-b>XXXX.iaa7_1.XXXX.ccss.XXXX.Stuff</class-b>
    <class-c>XXXX.XXXX.acord_pc_1_22.external.XXXX.PhoneInfoType</class-c>
    <field>
        <a>personName.GivenName.value</a>
        <b>quote.prospectName.firstName</b>
    </field>
    <field>
        <a>personName.Surname.value</a>
        <b>quote.prospectname.lastName</b>
    </field>
    <field custom-converter="XXXX.is.XXXX.converter.ListToListConverter" custom-converter-param="C40">
        <a>personName.OtherGivenName</a>
        <b>quote.prospectname.middleNames</b>
    </field>
    <field>
        <c>phoneNumber.value</c>
        <b>quote.prospectName.phone</b>
    </field>
</mapping>

解析和拆分：

<dependency>
    <groupId>org.jsoup</groupId>
    <artifactId>jsoup</artifactId>
    <version>1.12.1</version>
</dependency>

对于实际输出-您的loadData函数应为

public void loadData(String stream) throws IOException {
        String[] list = StringUtils.substringsBetween(stream, "<staff>", "</staff>");

        StringBuilder stringBuilder = null;
        System.out.println("##################################");
        for (String s : list) {
            stringBuilder=new StringBuilder();
            stringBuilder.append("<staff>");
            stringBuilder.append(s);
            stringBuilder.append("</staff>");
           // System.out.println("##################################");
            System.out.println(stringBuilder.toString());
            System.out.println("##################################");
        }

    }
