RE: parsing help for a slow learner

Seamus,

This is a job for regular expressions. First of all, include this function
in your page (it returns a structure containing all matches):


<CFFUNCTION NAME="REFindAll" OUTPUT="false" RETURNTYPE="struct">
   <CFARGUMENT NAME="regex" TYPE="string" REQUIRED="yes">
   <CFARGUMENT NAME="text" TYPE="string" REQUIRED="yes">

   
   <CFSET var results=StructNew()>
   <CFSET var pos=1>
   <CFSET var subex="">
   <CFSET var done=FALSE>

   
   <CFSET results.len=ArrayNew(1)>
   <CFSET results.pos=ArrayNew(1)>

   
   <CFLOOP CONDITION="NOT done">

      
      <CFSET subex=REFind(ARGUMENTS.regex, ARGUMENTS.text, pos, TRUE)>

      
      <CFIF subex.pos[1] IS 0>
         
         <CFSET done=TRUE>
      <CFELSE>
         
         <CFSET ArrayAppend(results.len, subex.len[1])>
         <CFSET ArrayAppend(results.pos, subex.pos[1])>
         
         <CFSET pos=subex.pos[1]+subex.len[1]>
      </CFIF>

   </CFLOOP>

   
   <CFIF ArrayLen(results.len) IS 0>
      <CFSET ArrayAppend(results.len, 0)>
      <CFSET ArrayAppend(results.pos, 0)>
   </CFIF>

   
   <CFRETURN results>
</CFFUNCTION>

Here is the processing itself:


<CFSET records=REFindAll("(BOOS\|).*?(BOOE\|)", myData)>


<CFLOOP INDEX="i" FROM="1" TO="#ArrayLen(records.pos)#">

<CFSET record=Mid(myData, records.pos[i], records.len[i])>
<CFOUTPUT>#record#</CFOUTPUT>
<HR>
</CFLOOP>

The REFindAll() call gets the matches, and the <CFLOOP> loops through them.
Then just replace the processing in the loop with your own processing.

Hope this helps.

Subject: parsing help for a slow learner

Hi

I'm hoping some-one can help me.
I have to parse a file to insert data into a database, and I'm
stuck on the initial parsing. (I have some sort of mental block
when it comes to this sort of stuff)

A sample of the file is at the bottom of this email.

each record is starts with BOOS| and ends with BOOE|

At the moment I am reading the file, then replacing the BOOS|
with a ~ and looping thru the file using the new delimiter (~)
This way I can get each record but I can't seem to then get each
field.

I have tried:

<CFFILE file="#myFile#" action="" variable="myData">
<cfset myDelim = "BOOS|">
<cfset myData = Replace(myData,myDelim,"~","ALL")>

<cfloop index="myLine" list="#myData#" delimiters="~">

<cfloop index="myRecord" list="#myLine#"
delimiters="#Chr(10)##Chr(13)#">

<cfset Field = left(Trim(myLine),4)>
<cfset Data = "" "|"))>


</cfloop>
<hr>

</cfloop>

But this seems to get BOOK and then the rest of the record ie
doesn't see a new line

Any help at all would be greatly appreciated

Seamus
