i want to replace the one data.xml file of power point presentation in java using apache API with other file data.xml
For the reference i want to replace the following file with another power point file.
Following is the code i have tried but xml isnt replacing. I have different XML for both files every time i run after replacing using this code
public static void main(String[] args) {
// TODO Auto-generated method stub
final String filename = "C:/Users/skhan/Desktop/game.pptx";
final String filename1 = "C:/Users/skhan/Desktop/globe.pptx";
try {
XMLSlideShow ppt = new XMLSlideShow(new FileInputStream(filename));
OPCPackage pkg = ppt.getPackage();
PackagePart data = pkg.getPart(
PackagingURIHelper.createPartName("/ppt/diagrams/data1.xml"));
InputStream data1Inp = data.getInputStream();
XMLSlideShow ppt1 = new XMLSlideShow(new FileInputStream(filename1));
OPCPackage pkg1 = ppt1.getPackage();
PackagePart data11 = pkg1.getPart(
PackagingURIHelper.createPartName("/ppt/diagrams/data1.xml"));
InputStream data1Inp1 = data11.getInputStream();
String data1String = GetData(data1Inp);
String data2String = GetData(data1Inp1);
//i want to replace here
PrintStream pr = new PrintStream(data.getOutputStream());
pr.print(data2String);
pr.close();
System.out.println("Completed");
} catch (Exception e) {
e.printStackTrace();
}
}
public static String GetData(InputStream input) throws Exception
{
StringBuilder builder = new StringBuilder();
int ch;
while((ch = input.read()) != -1){
builder.append((char)ch);
}
String theString = builder.toString();
return theString;
}
I added the few line after changing in order to save the file. The XMLSlideShow must write to some file after changing or adding.
