Check if node is null ASP

programming
1

I am parsing an XML file in ASP. It appears you can’t have an empty node or else I get this error:


Microsoft VBScript runtime  error '800a01a8'

Object required: 'objHdl.childNodes(...).childNodes(...)'

/post/resources/courses/DOP/vtod/index.asp, line 96

Sometimes the node will be populated other times it wont and I need to check that.

Here is my code that is reading the XML and outputting html:


Response.Write("<table width=""800"" cellpadding=""5"" cellspacing=""20"" border=""0"">" & vbCRLF)
For i = 0 To (noOfHeadlines - 1)
	needFooter = true
	Set objHdl = objLst.item(i)
	if i mod numCols = 0 then
		Response.Write("<tr>")
	end if
	Response.Write("<td class=""courseTable"" valign=""top"" width=""33%"">" & vbCRLF &_
	"<div id=""thumbs"" class=""thumb""><a tipcontent=""" & objHdl.childNodes(2).childNodes(0).text & """ href=""" & objHdl.childNodes(7).childNodes(0).text & """>" & vbCRLF &_
	"<img id=""thumb_" & headlineNum & """ border=""0"" src=""" & objHdl.childNodes(5).childNodes(0).text & """ onmouseover=""hoveron(" & headlineNum & ");"" onmouseout=""hoveroff(" & headlineNum & ");""/>" & vbCRLF &_ 
	"<div id=""playbtn_" & headlineNum & """ style=""position:relative; top: -80px; left: 0px; z-index:5; display:none;"">" & vbCRLF &_
	"<img border=""0"" src=""images/btn-play-big.png"" onmouseover=""hoveron(" & headlineNum & ");"" onmouseout=""hoveroff(" & headlineNum & ");""/>" & vbCRLF &_
	"</div></a></div>" & vbCRLF &_
	"<span class=""chantitle""><a href=""" & objHdl.childNodes(7).childNodes(0).text & """>" & objHdl.childNodes(1).childNodes(0).text & "</a></span><br />" & vbCRLF &_
	"<span class=""chanlength"">Length: " & objHdl.childNodes(6).childNodes(0).text & "</span><br />" & vbCRLF &_
	"<span class=""chanstatus"">" &	objHdl.childNodes(3).childNodes(0).text & "</span></td>" & vbCRLF)
//^^^ this line broken if empty^^^

	headlineNum = headlineNum + 1
	
	if i mod numCols = numCols - 1 then
		Response.Write("</tr>")
		needFooter = false
	end if
Next

if needFooter then
	Response.Write("<td colspan=""" & numCols - (i mod numCols) & """></td></tr>")
end if

Response.Write("</table>")

I’ve tried ‘if Not isNull(the node)’ and that didnt work. Anyone know how to do this?
