parse data fetch from html

I'm trying to get some data from the federal reserve and paste into my spreadsheet.

So here is my code

function myFunction() {
var response = UrlFetchApp.fetch("http://research.stlouisfed.org/fred2/data/TWEXMANL.txt");
a=response.getContentText();
var ss = SpreadsheetApp.getActiveSpreadsheet(); 
var InputSheet = ss.getSheetByName("Sheet5"); 
InputSheet.getRange("E5:E5").setValue(a); 
}

This code pastes all of the output into E5. I just want the data following the "Date" and "Value" pasted into 2 columns.

Can anybody help me with this? I'm sure it's pretty simple for you guys.

Thanks.

Using a little string manipulation, this becomes very easy:

function myFunction() {
  var response = UrlFetchApp.fetch("http://research.stlouisfed.org/fred2/data/TWEXMANL.txt");
  a=response.getContentText();
  var ss = SpreadsheetApp.getActiveSpreadsheet(); 
  var InputSheet = ss.getSheetByName("Sheet1"); 

  //Slice off the text above the columns
  var allData = a.slice(a.indexOf("DATE         VALUE"));

  //Trim spaces between date and value to just 1 space for splitting
  allData = allData.replace(/ +/g, " ");

  //Split the text so each line is a row
  var splitData = allData.split("\n");

  //For some reason, there is an extra line, so remove it
  splitData.pop();

  //Split each row so data is one column and value is another
  for(var i = 0; i < splitData.length; i += 1) {
    splitData[i] = splitData[i].split(" ");
  }

  //Save to spreadsheet. +4 because you start at E5. Note the change to F on the right.
  InputSheet.getRange("E5:F" + (splitData.length + 4)).setValues(splitData);
}

I start by taking off the little intro text. I then split the string into an array containing the rows of data. I split each row (a string) into an array as well. This gives me a array I can use setValues() on at the bottom. Because this isn't just one cell, I have to specific the exact width and height or it fails.

If you'd like to see the data at any point in there, I recommend Logger.log(splitData);
