Default ASP output returned to IFrame

I have a bit of code that calls an ASP file which, among other things, returns the contents of an XML file to an IFrame in my original page. The first time this is launched, all is well. The resulting document shows up perfectly within the IFrame. However, if I click again on a link that executes this process again, the resulting file takes over the whole browser window, rather than staying within the IFrame.

Is this something I can correct?

Below are the relevant lines from the originating .XML page:

<a href="showdoc.asp?filepath={source/@location}&amp;filename={source/@filename}" target="viewframe">
<xsl:value-of select="case"/>
</a>

<IFRAME class="viewer" name="viewframe" src="instructions.html" />

You have to define the target to all your links in order to open the page in the IFrame. The other solution is to place the <base> tag to the head of the page that contains the links, with the target attribute equal to the Iframe name, e.g <base target="viewframe">

Thank you for your reply.

The page containing the links is an XML page, formatted with XSL. The links in question are generated by an <xsl:for-each> loop, so the "target" is specified on each link, as the template does the work.

I added the <base> tag as you mentioned, but it made no difference.

By the way, the showdoc.asp file is feeding a .xml file back to the frame with the snippet below. It was suggested that I use Response.Redirect in place of this subroutine instead, but that only generates the error "Object doesn't support this property or method.":

    Set TS = objFSO.OpenTextFile(strFilename, ForReading, Create)
    If Not TS.AtEndOfStream Then
        Do While Not TS.AtEndOfStream
            strLine = TS.ReadLine
            Response.Write strLine
        Loop
    End If

Thanks again for your help.

Ken

The Base Target idea didn't work. My eventual solution to this was to use Microsoft's msxsl.exe utility to output the HTML from the xml/xsl files.

The HTML file does not exhibit the problem. Could it be that xml/xsl and internal frames just don't work well together?
