Question

I have written code in Java to merge two xml file,
the first file is:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<dependency>
<ownedtestcase ID="UT001_GetPatientInfo" Package="emrservicedesigntest" source="EMRService">
<cutdependency ID="EMRService" Package="emrservicedesign"/>
</ownedtestcase>
</dependency>`  

The second file is:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<dependency>
<ownedtestcase ID="UT001_ScheduleTreatment" Package="emrservicedesigntest" source="EMRService">
<cutdependency ID="Symptom" Package="emrservicedesign"/>
<cutdependency ID="PatientInfo" Package="emrservicedesign"/>
</ownedtestcase>
</dependency>      

My code produced the following merged output xml file:

 <dependency>
 <?xml version="1.0" encoding="UTF-8" standalone="no"?>
<ownedtestcase ID="UT001_GetPatientInfo" Package="emrservicedesigntest" source="EMRService">
<cutdependency ID="EMRService" Package="emrservicedesign"/>
</ownedtestcase>

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<ownedtestcase ID="UT001_ScheduleTreatment" Package="emrservicedesigntest" source="EMRService">
<cutdependency ID="Symptom" Package="emrservicedesign"/>
<cutdependency ID="PatientInfo" Package="emrservicedesign"/>
</ownedtestcase>
</dependency>` 

This is my code in java:

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileInputStream;
import java.io.FileWriter;
import java.io.InputStreamReader;
import java.io.Writer;

public class Class {

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

// Creates file to write to
Writer output = null;
output = new BufferedWriter(new FileWriter("merged_xml.xml"));
String newline = System.getProperty("line.separator");
output.write("<dependency>");

// Read in xml file 1
FileInputStream in = new FileInputStream("C:/Users/modifiedscheduletreatment.xml");
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;

while ((strLine = br.readLine()) != null) {

if (strLine.contains("<dependency>")){
strLine = strLine.replace("<dependency>", "");
}
if (strLine.contains("</dependency>")){
strLine = strLine.replace("</dependency>", "");
}

output.write(newline);
output.write(strLine);

//System.out.println(strLine);
}

// Read in xml file 2
FileInputStream in2 = new FileInputStream("C:/Users/modifiedgetpatientinfo.xml");
BufferedReader br2 = new BufferedReader(new InputStreamReader(in2));
String strLine2;

while ((strLine2 = br2.readLine()) != null) {

if (strLine2.contains("<dependency>")){
strLine2 = strLine2.replace("<dependency>", "");
}
if (strLine2.contains("</dependency>")){
strLine2 = strLine2.replace("</dependency>", "");
}

output.write(strLine2);
output.write(newline);
//System.out.println(strLine2);
}

output.write("</dependency>");
output.close();

System.out.println("Merge Complete");

}

}

You can notice that I have two header in the output file unfortunately, since I have two xml file, and the root becomes before header, I don’t know what should I modify to fix these two problems in the merged output xml file. Thanks in Advance

The expected output file must look like

 <?xml version="1.0" encoding="UTF-8" standalone="no"?>
 <dependency>
  <ownedtestcase ID="UT001_GetPatientInfo" Package="emrservicedesigntest" source="EMRService">
<cutdependency ID="EMRService" Package="emrservicedesign"/>
</ownedtestcase>

<ownedtestcase ID="UT001_ScheduleTreatment" Package="emrservicedesigntest" source="EMRService">
<cutdependency ID="Symptom" Package="emrservicedesign"/>
<cutdependency ID="PatientInfo" Package="emrservicedesign"/>
</ownedtestcase>
</dependency>

It seems you are just missing removing the XML header tags. You need to add another filter, similar to how you took out the dependency tags, for the XML header tags.
