SUMMARY

This is a simple example of how the Microsoft XML parser (MSXML) object can be used to move XML data from an XML document into a Microsoft FoxPro table. A FoxPro table similar in structure to the Orders table is created and the data in the XML document is moved to the table.

MORE INFORMATION

This example uses the MSXML parser to move data from an XML document to a FoxPro table. The parser is available at:

This code takes the XML document below, creates a new table called SampOrd and populates the table with the XML data.

NOTE: Ensure that any XML document to be used as a datasource for the sample code below has a root tag or basename in the document; otherwise an error might occur.

  1. Install the MSXML parser.
  2. Create an XML document from the XML code below.
  3. Create a FoxPro program file with the following code and then run the program:

    CREATE TABLE SampOrd (  ;
        order_id    c(10), ;
        cust_id     c(10), ;
        emp_id      c(10), ;
        to_name     c(25), ;
        to_address  c(50), ;
        to_city     c(25), ;
        to_region   c(10), ;
        postalcode  c(10), ;
        to_country  c(15), ;
        ship_count  c(15), ;
        ship_via    c(6),  ;
        order_date  c(8),  ;
        order_amt   c(10), ;
        order_dsc   c(10), ;
        order_net   c(10), ;
        require_by  c(8),  ;
        shipped_on  c(8),  ;
        freight     c(10))
    
    *** Uncomment the following line if you want access to oXML 
    *** outside of this program.
    *PUBLIC oXML  
    
    oXML=CREATEOBJECT('msxml.domdocument')  && This creates the parser object
    oXML.LOAD(GETFILE('xml'))  && This gets and loads the XML document. 
    
    *** Select the XML document created from the XML code below.
    *** The following gives the basename of the XML document
    *?oXML.DocumentElement.Basename 
    *** The following gives the number of nodes (or records)           
    *?oXML.documentelement.childnodes.LENGTH  
    
    ** The following snippet appends a blank record and parses 
    ** through each node element and adds it to the table.
    
    ** REMEMBER that the object model is in base zero.
    WITH oXML.DocumentElement.ChildNodes
        FOR iCount = 0 TO .LENGTH - 1
            APPEND BLANK
            FOR iChild = 0 TO .ITEM(0).ChildNodes.LENGTH - 1
                lcVar = .ITEM(iCount).ChildNodes(iChild)
                REPLACE (lcVar.NodeName) WITH (lcVar.TEXT)
            ENDFOR
        ENDFOR
    ENDWITH

  • If a root tag or basename is not in the XML document, usually an "OLE error 0x00000001: Incorrect function" error occurs.
