I got the function to work, it was a matter of needing to javacast() the
numbers before passing them to the substring() function, here is the final
code for anyone interested. I am using this function to get specific html
elements from a page. In my case the needed elements are wrapped with
specific <div> tags. For example:
<cfset preString = "<div id='currentprice'>">
<cfset postString = "</div>">
<cfset loc = stripPrice(weeklyReport, preString, postString)>
<cfscript>
function stripPrice(pageHtml, prePriceString, postPriceString) {
// look for the prePriceString
preStringLoc = pageHtml.indexOf(prePriceString);
if(preStringLoc eq -1)
{
msg = "Coulden't find the prePriceString " +
prePriceString;
throw(msg);
}
// Found the prePriceString, so look for the post
postStringLoc = pageHtml.indexOf(postPriceString, preStringLoc);
if(postStringLoc eq -1)
{
msg = "Coulen't find the postPriceString " +
postPriceString;
throw(msg);
}
returnPrice = pageHtml.substring(javaCast("int",preStringLoc +
prePriceString.length()), javaCast("int", postStringLoc));
return returnPrice;
}
</cfscript>
