variable dissapearing!

Hi,
I'm using ASP to retrieve simple information from an XML file. I set a variable on the asp page that gets the information from XML if they match.

It is supposed to write out the answer but for some reason the variable on the asp page is not matching the value on the XML page even though they are the same.

Code:

<% 
Var1 = 3 
response.write "CD: " 
response.write Var1 & "<BR>"

' open xml file to compare

Set objXML = Server.CreateObject("Microsoft.XMLDOM") 
objXML.async = False 
objXML.Load(Server.MapPath("check.xml")) 
Set objLst = objXML.getElementsByTagName("list") 
intNoOfHeadlines = objLst.length 
For i = 0 To intNoOfHeadlines-1
'the code below is not matching
if objLst.item(i).childNodes(0).text = Var1 then 
response.write objLst.item(i).childNodes(1).text 
response.write " category is selected" 

end if 
Next 
%>

the xml file

Code:

<?xml version="1.0" encoding="ISO-8859-1"?> 
<Menu> 
<list> 
<cd>1</cd> 
<category>6</category> 
</list> 
<list> 
<cd>2</cd> 
<category>6</category> 
</list> 
<list> 
<cd>3</cd> 
<category>7</category> 
</list> 
<list> 
<cd>4</cd> 
<category>8</category> 
</list> 
</Menu>

Var1 = 3 and there is a tag with value 3 in the xml so its suposed to print out childnode(1) which is 7.

The weird thing is if i use the line

Code:

if objLst.item(i).childNodes(0).text = 3

instead of

Code:

  
if objLst.item(i).childNodes(0).text = Var1

it works but i want to be able to have the value in a variable.

Can anyone help? Thanks.

The reason you are not getting a match is that the statement

Var1 = 3

sets Var1 to numeric 3, whereas the string you are comparing to is text. Numeric 3 and text 3 are not the same. So try one of the following, declare Var1 as text by using

Var1 = "3"

Or try accessing Var1 as text using

Var1.text

One of these should work.
