com.google.clearsilver.jsilver.template.HtmlWhiteSpaceStripper

HTML whitespace stripper to be used by JSilver. It removes leading and trailing whitespace, it reduces contiguous whitespace characters with just the first character, and removes lines of nothing but whitespace. It does not strip whitespace inside the following elements:

PRE
VERBATIM
TEXTAREA
SCRIPT

It also strips out empty lines and leading whitespace inside HTML tags (i.e. between '<' and '>') and inside SCRIPT elements. It leaves trailing whitespace since that is more costly to remove and tends to not be common based on how templates are created (they don't have trailing whitespace).

Loadtests indicate that this class can strip whitespace almost as quickly as just reading every character from a string (20% slower).

While not strictly compatible with the JNI Clearsilver whitestripping function, we are not aware of any differences that yield functionally different HTML output. However, we encourage users to verify for themselves and report any differences.

      // For Clearsilver compatibility we check this HDF variable to see if we
      // need to turn on whitespace stripping. The preferred approach would be
      // to turn it on in the JSilverOptions passed to JSilverFactory
      int wsStripLevel = localHdf.getIntValue("ClearSilver.WhiteSpaceStrip", 0);
      if (wsStripLevel > 0) {
        output = new HtmlWhiteSpaceStripper(output, wsStripLevel);
      }
      jSilver.render(template, data, output, resourceLoaderAdaptor);
      return output.toString();
    } catch (IOException ioe) {
      throw new RuntimeException(ioe);

  @Override
  public void render(Template template, Data data, Appendable output, ResourceLoader resourceLoader)
      throws IOException, JSilverException {
    if (options.getStripHtmlWhiteSpace() && !(output instanceof HtmlWhiteSpaceStripper)) {
      // Strip out whitespace from rendered HTML content.
      output = new HtmlWhiteSpaceStripper(output);
    }
    template.render(data, output, resourceLoader);
  }
