StringtoHTML(String xhtml)

int startPos, endPos;
while ((startPos = xhtml.indexOf("<?")) != -1 && (endPos = xhtml.indexOf("?>")) != -1) {
    xhtml = xhtml.substring(0, startPos) + xhtml.substring(endPos + 2);
while ((startPos = xhtml.indexOf("/>")) != -1) {
    xhtml = xhtml.substring(0, startPos) + xhtml.substring(startPos + 1);
return xhtml;
