While using Print Anything, I extended the driver to include support for an equals tag. If anyone is using print anything, I found this very helpful when creating more advanced templates. It also supports nested equal statements.

Here's how it works:

<prtany:equal Contact1.FirstName="some value" Contact1.LastName="some other value" ........ >
  
    Displays this text only if:
    Contact1.FirstName="some value" and
    Contact1.LastName="some other value"

    <prtany:equal Contact1.LastName="some other value 2">
  
        Displays this text only if:
        Contact1.LastName="some other value 2" and
        parent equals tag is true

    </prtany:equal>

</prtany:equal>

<prtany:equal Contact1.FirstName!="some value" >
  
    Displays this text only if:
    Contact1.FirstName does not equal "some value"

</prtany:equal>



(Put new code inside the merge function after the last while statement)

Code:

 // remove any conditional content
 while (result.indexOf("<prtany:equal") != -1) {
  var level = 1;
  
  // Find next start tag (<prtany:equal ... >)
  var startTagStartPos = result.indexOf("<prtany:equal");
  var startTagEndPos = result.indexOf(">", startTagStartPos);

  var parsePos = startTagEndPos;
  
  var nextStartTagPos;
  var nextEndTagPos;
  
  // Find corresponding end tag (</prtany:equal>)
  do {
   nextStartTagPos = result.indexOf("<prtany:equal",parsePos);
   nextEndTagPos = result.indexOf("</prtany:equal", parsePos);
   if( nextStartTagPos < nextEndTagPos && nextStartTagPos != -1 ) {
    level = level + 1;
    parsePos = nextStartTagPos + 1;
   } else {
    level = level - 1;
    parsePos = nextEndTagPos + 1;
   }
  } while ( level > 0 )

  if (nextEndTagPos == -1) {
   throw "No equal end tag was found";
  }

  var endTagEndPos = result.indexOf(">", nextEndTagPos);
  
  var conditionalString = result.substring(startTagEndPos+1,nextEndTagPos);

  // Parse start tag conditions (<prtany:equal var="value" var2!="value" ... >
  var statement = result.substring(startTagStartPos+1,startTagEndPos);
  var reg = /(\S+?)\s*(\!?=)\s*\"(.+?)\"/g;
  
  var match = reg.exec( statement );
  while( match != null ) {
   var conditionalValue = mergeData[match[1]];
   if( match[2] == "!=" ) {
    if (conditionalValue == match[3]) {
     conditionalString = "";
    }
   } else {
    if (conditionalValue != match[3]) {
     conditionalString = "";
    }
   }
   match = reg.exec( statement );
  }

  result = result.substring(0,startTagStartPos) + conditionalString + result.substring(endTagEndPos+1)
 }
