How to delete 1st 2 rows in a csv/excel file?

Question

Hi,
Is there a way to read a csv file and delete the 1st 2 rows  (or any no. of rows I would like to)?
I'm currently using Ben Nadel's GREAT piece of code (Parsing CSV Values into a Coldfusion query) found at http://www.bennadel.com/index.cfm?dax=blog:501.view as follows:
<!--- Read file --->
<cffile action="read" file="#variables.uploadedFile#" variable="csvResult">
<!--- Invoke method to convert csv data to query --->
<cfinvoke component="components.csvToQuery" method="CSVToQuery" returnvariable="qCsvData">
     <cfinvokeargument name="CSV" value="#trim(variables.csvResult)#">
     <cfinvokeargument name="FirstRowIsHeadings" value="true">
</cfinvoke>
I need to manipulate qCsvData to delete the 1st 2 rows.
Any ideas would be most welcome.
Thanks and regards,
Yogesh Mahadnac

Hi Joseph,
Thanks again for your brilliant answer!
I still need you help by the way, if you don't mind, of course!
I've based myself on your logic and tried to implement it differently.
(apologies if it's a bit complicated. it's almost 1 o'clock in the morning here, and sleep is getting over...)
Here is what I've done:
Now, I know that I need to ignore the 1st 2 rows, which means, my headers in fact start on the 3rd row.
I've created my column names dynamically and then added rows to my query object.
<cffunction name="removeRecords" returntype="Query" output="false" description="I remove records from a query.">
     <cfargument name="queryObject" type="Query" required="true" hint="Query to remove records from" />
     <!--- Initialise function local variables --->
     <cfset var myQry = QueryNew("")>
     <cfset var i = 0>
     <cfset var j = 0>
     <cfset var columnName = "">
     <cfset var columnList = "">
     <cfset var tempList = arguments.queryObject.columnList>
    <!--- Loop query --->
    <cfloop index="i" from="1" to="#arguments.queryObject.recordcount#">
        <!--- Ignore 1st 2 rows, 3rd row is header --->
        <cfif i gt 2>
            <cfif i eq 3><!--- Create headers --->
                <!--- Loop column list (column_1, column_10, ...) --->
                <cfloop index="j" from="1" to="#listLen(tempList)#">
                    <cfset item = ListGetAt(tempList,j)>
                    <!--- Remove blank spaces --->
                    <cfset columnName = replaceNoCase(trim(arguments.queryObject[item][i])," ","_","All")>
                    <!--- Remove slash --->
                    <cfset columnName = replaceNoCase(trim(columnName),"/","_","All")>
                    <!--- Create column name --->
                    <cfset QueryAddColumn(myQry,columnName,"cf_sql_varchar",ArrayNew(1))>
                    <!--- Create list of column names --->
                    <cfset columnList = columnList & columnName & ",">
                </cfloop>
                <!--- Remove trailing comma --->
                <cfset columnList = left(columnList,len(columnList)-1)>
            <cfelse><!--- As from 4th row, we add 1 new row to myQry for each iteration --->
                <!--- Add rows --->
                <cfset QueryAddRow(myQry)>
                <cfloop index="j" from="1" to="#listLen(tempList)#">
                    <cfset item = ListGetAt(tempList,j)>
                    <cfset fieldValue = trim(arguments.queryObject[item][i])>
                    <cfset col = listGetAt(columnList,j)>
                    <cfset QuerySetCell(myQry,col,fieldValue)>
                </cfloop>
            </cfif>
        </cfif>
    </cfloop>
     <cfreturn myQry>
</cffunction>
Question:
Is there a simpler way to do the following?
<cfset columnName = replaceNoCase(trim(arguments.queryObject[item][i])," ","_","All")>
<cfset columnName = replaceNoCase(trim(columnName),"/","_","All")>
I'm trying to replace all blank spaces and any "/"  between words with an "_".
I know we can use Regular Expressions to do it much simpler, but I'm not very familiar with the syntax.
I'd be grateful if you could please provide me with the correct syntax.
Thanks in advance.
Best regards,
Yogesh
