Highlight code in blogger using syntaxhighlighter

2010-06-24T18:39:00.001-07:00

I want to highlight my code in blooger,and I do some web search ,It looks like there is
a good choice called syntaxhighlighter,It's pure javascipt.I read the install faq,but It seems difficult to use it in blogger,and I search again for how to use it in my blog.luckly I found two artical about using syntaxhighlighter,so I combination the two method and I success. here is the way I got it:
edit the template code in blogger
add this code to the end of template:


<script class='javascript'>
//<![CDATA[
  function FindTagsByName(container, name, Tag)
  {
      var elements = document.getElementsByTagName(Tag);
      for (var i = 0; i < elements.length; i++)
      {
          if (elements[i].getAttribute("name") == name)
          {
              container.push(elements[i]);
          }
      }
  }
  var elements = [];
  FindTagsByName(elements, "code", "pre");
  FindTagsByName(elements, "code", "textarea");

for(var i=0; i < elements.length; i++) {
if(elements[i].nodeName.toUpperCase() == "TEXTAREA") {
 var childNode = elements[i].childNodes[0];
 var newNode = document.createTextNode(childNode.nodeValue.replace(/<br\s*\/?>/gi,'\n'));
 elements[i].replaceChild(newNode, childNode);

}
else if(elements[i].nodeName.toUpperCase() == "PRE") {
 brs = elements[i].getElementsByTagName("br");
 for(var j = 0, brLength = brs.length; j < brLength; j++) {
  var newNode = document.createTextNode("\n");
  elements[i].replaceChild(newNode, brs[0]);
 }
}
}
//clipboard does not work well, no line breaks
// dp.SyntaxHighlighter.ClipboardSwf =
//"http://[YOUR HOST]/clipboard.swf";
dp.SyntaxHighlighter.HighlightAll("code");
//]]>

when I down load poderosa(a excelent ssh client),and this error occured:

Parameter name: startIndex""

int LocalShell.cs

char[] buf = new char[XXX];
int n = Win32.GetEnvironmentVariable("PATH", buf, buf.Length);

XXX is the buffer size for enviroment PATH,and my PATH is too long to filled in the buf,

I change XXX up to 8096 and Everything goes well.
