Feature request: replace text

[GoogleCodeExporter]

Along similar lines to the color replacement request, is there a chance of 
adding the ability to replace the contents of  one or more text elements, 
preferably by an ID match, but a regexp based search and replace may also be 
useful e.g.

svg.getTextElementById(id).setValue(string);
svg.getTextElementByValue(regexp).setValue(string);

My intention at some point is to support the SVG DOM.  You will then be able to 
manipulate any part of the SVG before rendering.

Thanks, will look forward to having a play.

As a stopgap I've just made a quick fork / hack, so the likes of:
getElementById(String) and getElementsByTagName(Class), and TextSequence()
are now public and a: setTextSequenceById(String, String) has magically
appeared. A bit of a frig as even for my limited requirements.

Oh spotted what appears to be a typo in getElementsByTagName, shouldn't the
recursive call be prefixed by a: result.addAll( )   e.g.

   private List<SvgObject>  getElementsByTagName(SvgContainer obj, Class
clazz)
   {

...

         if (child instanceof SvgContainer)
             result.addAll(getElementsByTagName((SvgContainer) child,
clazz));
             ^^^^^^^^^^^^^
      }
      return result;
   }

Thanks for catching that bug!  I'll fix it for the next release.

FYI / to comply with the Licence, I've created a custom version of SVG.java 
that includes the bugfix above and adds the following two functions:

public int setTextById(String id, String newText) {
        int updated = 0;

        if (id == null || id.length() == 0 || newText == null)
            return updated;

        SvgObject idMatch = getElementById(id);

        if ( idMatch != null) {
            List<SvgObject> allText = getElementsByTagName((SvgContainer) idMatch, TextSequence.class);

            //Should only find one child element, but to be safe
            for (SvgObject textSeq : allText) {
                ((TextSequence) textSeq).text = newText;
                updated++;
            }
        }
        return updated;
    }

    public int replaceTextById(String id, String oldText, String newText) {
        int updated = 0;

        if (id == null || id.length() == 0 || newText == null || oldText == null)
            return updated;

        SvgObject idMatch = getElementById(id);

        if ( idMatch != null) {
            List<SvgObject> allText = getElementsByTagName((SvgContainer) idMatch, TextSequence.class);

            //Should only find one child element, but to be safe
            for (SvgObject textSeq : allText) {
                ((TextSequence) textSeq).text = ((TextSequence) textSeq).text.replace(oldText, newText);
                updated++;
            }
        }
        return updated;
    }
