Selecting certain XML elements

fogofogo · December 2nd, 2005, 02:06 PM

Hello All,
I have a question regarding searching and selecting certain elements in an XML document using asp. The xml script basically consist of news headings, contents, date, and category elements that tell what the news is related to and where it should be displayed and stored. For example Finance catagory stories will be stored in a different database to the business one.

Code:

<Article Created="16:01:59" ID="15105602">
   <Heading>Equitable drops claim against former directors</Heading> 
   <Date>02/12/2005</Date> 
  <Contents>
   <news story goes in here> 
   </Contents>
  <Categories>
    <Category ID="430009725">Finance</Category> 
   <Category ID="430009734">Economy</Category> 
   <Category ID="430009735">Business</Category> 
    <Category ID="438000159">Insurance</Category> 
  </Categories>
</Article>

So basically I need a script that can check the XML for certain stories and store them in a database. I already have the script (see below) that takes ALL the news stories from the XML file and puts them in a database. So how can I get the script to check if a story is, say a Finance story and continue to store it in a database? Would I use an if else statment? if so, where should I put it?

Code:

Dim XMLDom
Dim ItemID
Dim DbConn
Dim SQLString
Dim ANArticleNode
Dim CollectionOfArticleNodes
Dim cst
Set XMLDom = CreateObject("MSXML2.DomDocument.4.0")
XMLDom.async = False
XMLDom.setProperty "ServerHTTPRequest", True
Set DbConn = Createobject("adodb.connection")
'DbConn.open "DRIVER={MySQL ODBC 3.51 Driver}; SERVER=localhost; DATABASE=pokernewsxml; OPTION=3"
DbConn.open "Driver={MySQL ODBC 3.51 Driver};" & _ 
        "Server=82.195.128.88;" & _ 
        "Database=johnfog_xml;" & _ 
        "Uid=johnfog_xml;" & _ 
        "Pwd=wordword;"

'-- Load the XML data from your live URL
XMLDom.Load("http://feeds.directnews.org.uk/?ad96...2-ad546b2ed850") 
'-- Create a reference to a collection of all Article Tags within the downloaded XML Document
Set CollectionOfArticleNodes = XMLDom.SelectNodes("InfoStreamResults/Article")
'-- Iterate the collection of Article Tags 
For Each ANArticleNode in CollectionOfArticleNodes 
 ItemID = ANArticleNode.SelectSingleNode("@ID").text
 Heading = ANArticleNode.SelectSingleNode("Heading").text 
 Contents = ANArticleNode.SelectSingleNode("Contents").text
 sDate = ANArticleNode.SelectSingleNode("Date").text
 '-- Delete the item from the local database if it exists
 SQLString = "DELETE FROM DeHavillandNews WHERE trim(ItemID)='" & trim(ItemID) & "';"
    DbConn.Execute(SQLString)
 
 '-- Insert the item into the local database
 SQLString = "INSERT INTO DeHavillandNews (ItemID,Heading,Contents,strDate) " _
    & "VALUES('" & ItemID & "','" & EncodeIt(Heading) & "','" & EncodeIt(Contents) & "', '" & sDate & "');" 
 DbConn.Execute(SQLString) 
 
Next
 
'-- Handles quotations in text
Function EncodeIt(TextString)
 TextString = Replace(CStr(TextString), "''", "'")
 TextString = Replace(TextString, "'", "''")
 EncodeIt = TextString
End Function

Any help would be greatly appreciated as I am seriously stuck with this one.
Thanks folks
J

problem solved

If anyone is interested, here is the solution:

Code:

Dim XMLDom
Dim ItemID
Dim DbConn
Dim SQLString
Dim ANArticleNode
Dim ANArticleNode2
Dim CollectionOfArticleNodes
Dim CollectionOfArticleNodes2
Dim cst
Set XMLDom = CreateObject("MSXML2.DomDocument.4.0")
XMLDom.async = False
XMLDom.setProperty "ServerHTTPRequest", True
Set DbConn = Createobject("adodb.connection")
DbConn.open "DRIVER={Microsoft Access Driver (*.mdb)};DBQ=test1.mdb"
'-- Load the XML data from your live URL
XMLDom.Load("http://feeds.directnews.org.uk/?ad96...2-ad546b2ed850") 
'-- Create a reference to a collection of all Article Tags within the downloaded XML Document
Set CollectionOfArticleNodes = XMLDom.SelectNodes("InfoStreamResults/Article")
'-- Iterate the collection of Article Tags 
For Each ANArticleNode in CollectionOfArticleNodes 
 '-- Now create a reference to the category tag
 Set CollectionOfArticleNodes2 = ANArticleNode.SelectNodes("Categories/Category")
 '-- And iterate through the nodes to test for a match
 For Each ANArticleNode2 in CollectionOfArticleNodes2
  ItemID = ANArticleNode2.SelectSingleNode("@ID").text
  if ItemID = "430009735" then
   '-- Retrieve the value of the heading node from the current article
   Heading = ANArticleNode.SelectSingleNode("Heading").text
 
   '-- Insert the item into the local database
   SQLString = "INSERT INTO test (Heading) " _
   & "VALUES('" & EncodeIt(Heading) & "');" 
   DbConn.Execute(SQLString) 
  end if
 Next '-- check the next category ID
Next '-- move to the next article
'-- Handles quotations in text
Function EncodeIt(TextString)
 TextString = Replace(CStr(TextString), "''", "'")
 TextString = Replace(TextString, "'", "''")
 EncodeIt = TextString
End Function
