Question

XML Ending tags for Parents in loop

Asked by: jfergy

Hello-

I have the following code that puts in the change of area when a new area is available as the parent. However, I cant figure out what is the best solution for creating the closing parent tag after it has looped through the area iteration. With the current code it creates the Parent and closing parent tag after just 1 record. However, I need all records for a parent to fall within the tags. So the closing parent tag should only change when there is a new area. I am guessing and array to ubound of the count from area but not sure.

Do While not(getAds.EOF) 
 
nextArea = getAds.fields("Area")
 
if nextArea <> currentArea then
%>
<<%=Replace(Replace(Left(ApplyXMLFormatting(getAds("Area")),len(getAds("Area"))-6)," ",""),"(87)","")%>>
<%
end if
'Change this to match your folder:
Photo = getAds("Photo")
MagPhoto = ""
 
if objFileSystem.FileExists(ImagesLocation & "\" & Photo) then
	Magphoto = "http://www.mytomlinson.com/BoiseAdPix/" & Photo
else
	MagPhoto = "images/nophoto.png"
end if
%>
<Ad>
<Image href="<%=ApplyXMLFormatting(MagPhoto)%>"/>
<Address><%=ApplyXMLFormatting(getAds("Address"))%></Address>
<Price><%=FormatCurrency("0" & getAds("Price"),0)%></Price>
<Info><%=ApplyXMLFormatting(getAds("AdText"))%></Info>
<City><%=ApplyXMLFormatting(getAds("CityName"))%></City>
<Bedrooms><%=getAds("Bedrooms")%>BR</Bedrooms>
<Baths><%=getAds("Bathrooms")%>BA</Baths>
<ASF><%=getAds("AssessedSqFt")%> Sq.Ft.</ASF>
<% if CatID = "2" then%><OHDAY><%=getAds("OHDAY")%></OHDAY>
<StartTime><%=getAds("StartTime")%></StartTime>
<EndTime><%=getAds("EndTime")%></EndTime>
<Directions><%=ApplyXMLFormatting(getAds("Directions"))%></Directions>
<% end if %><MLS>#<%=getAds("ListingNumber")%></MLS><AgentName><%=getAds("DisplayAgent")%><%=getAds("DisplayAgentPhone")%></AgentName></Ad><%
if nextArea <> currentArea then
%>
</<%=Replace(Replace(Left(ApplyXMLFormatting(getAds("Area")),len(getAds("Area"))-6)," ",""),"(87)","")%>>
<%
end if
currentClass = nextClass
getAds.MoveNext 
Loop

Maybe a simpler way of putting this is I need the open area tag, whatever data is in that area with <ad>, then the closing tag of that area, before putting in the new area.

 

by: jfergyPosted on 2009-09-22 at 11:27:36ID: 25395923

Any help here? Another way of putting this is show the area, run all the loop for everything in that area, thn show the end of the area before showing the next one?

I find it a bit difficult to see the wood for the trees. I assume that you are storing your data in an XML file, which you need to update. I'd like to suggest an alternative processing strategy and also ask if you could post the structure of the file.

I do these things using an XML DOM which I create with Javascript (VBScript) :-

 var xmldom = CreateObject('Microsoft.XMLDOM');
 xmldon.async = false;
  xmldom.load('c:\dir\file.xml');

If it is the first time I create the file with FSO and set it to an empty document (<root></root>)

Now the entries are all of the type <entry id="someidnumber">...........</entry>

so I look for the entry to update :

var entry = xmldoc.selectSingleNode('/root/entry[@id=' + parameterForTheId + ']');

if entry=nothing I create a new entry with that id and the data, select the root element and append :-

      entry = xmldom.createElement('entry');
      ...here a bit of code for all the data bits.....
     var root = xmldom.documentElement;
     root.appendChild(entry);

else
    I have found the entry needed and can now select the data elements under it one after the other and update them

end if.

Now to write the file back I use FSO again getting the data to write by xmldom.xml or by using the xmldom.save method.

Hope that's a start.

BigRat-

Thanks for the response. My data is coming from an ADO result set and I am outputting to XML. So I am trying to create a parent tag, all data for that parent tag and then the ending parent tag. I can create the start tag from my code which works fine, however keeping track to show the end parent tag after the child nodes are complete is where i am lost as my variable is defined by the current record set not the previous.

It should go something like this :-

currentArea = ""

Do While not(getAds.EOF)
 
nextArea = getAds.fields("Area")
 
if nextArea <> currentArea then
   if currentArea <>"" then
%>
</<%=Replace(Replace(Left(ApplyXMLFormatting(currentArea),len(currentArea)-6)," ",""),"(87)","")%>>%>
<%
    end if
<<%=Replace(Replace(Left(ApplyXMLFormatting(nextArea),len(nextArea)-6)," ",""),"(87)","")%>>
<%
   currentArea = nextArea
end if

which ensures that the pervious tag is closed when the area changes and a start tag is emitted. If you then need to refer to the area name again it is ALWAYS in the variable currentArea.

The end of the loop does NOT need to bother with the area change, so simply delete these lines :-

if nextArea <> currentArea then
%>
</<%=Replace(Replace(Left(ApplyXMLFormatting(getAds("Area")),len(getAds("Area"))-6)," ",""),"(87)","")%>>
<%
end if

Now the ONLY last problem is that after the loop has closed an end of area tag is missing, and the area name is currentArea, so simply add this code after the loop statement

%>
</<%=Replace(Replace(Left(ApplyXMLFormatting(currentArea),len(currentArea)-6)," ",""),"(87)","")%>>%>
<%

(I'm assuming here that your Replace statements are correct)
