    How to convert xslt file into string

      i'm writting a java program to use xslt to transform the xml file. i'm encountering the problem when i try to convert the xslt file into string. i've defined my utility class called 'XmlUtil' to carry out the operation of transform xml file through xslt. but in my main java program i need to convert both xml and xslt file into a string in order to input them in my function argument. my function argument is as follows:
      String htmlString = XmlUtil.applyXsltString(xmlContent, xsltString);

      i've already converted xmlcontent into string by using:
      xmlContent = xmlContentBuffer.toString();

      but i don't know how to convert 'xsltString' now ? i've searched the google for an hour but i cannot find the solution. anyone can help ?

      detail of my souce code is as follow:

      in = conn.getInputStream();
      byte[] buffer = new byte[1024];
      int numRead;
      long numWritten = 0;
      System.out.println (in.toString ());
      while ((numRead = in.read(buffer)) != -1) {
      out.write(buffer, 0, numRead);
      numWritten += numRead;
      temp = new String(buffer);
      System.out.println(localFileName + "\t" + numWritten);
      xmlContent = xmlContentBuffer.toString();

      String htmlString = XmlUtil.applyXsltString(xmlContent, xsltString);
      } catch (Exception exception) {

          I don't understand why you need load the XML and XLS files into a String. A Transformer can be constructed from a Source and there is a StreamSouce which can be constructed from an InputStream. The transform() method can take a Source as input and can produce a Result. There is no need to go near a String representation of either the input.
          • 2. Re: How to convert xslt file into string
            Agreed. And besides, the cumbersome procedure you have there for reading the file into a String ignores the encoding of the XML document. This could cause problems. You have access to XML-processing classes that handle that properly. You should use them.

              en, i think i just want to try whether this way works or not. honestly, i haven't thought of encoding of xml document problem yet. but at this stage i just want to see whether i convert both of them into string file works or not. can anyone tell me how to convert the xslt file into string ?

                I don't see why it's so important to you to do the wrong thing. If this XMLUtil thing is forcing you into using Strings, you should stop using it.

                You would read the XSLT file into a String in exactly the same way you read the XML file into a String, wouldn't you?
