Issue in unterminated regular expression literal with eval() function

Why do you wrap strdata.replace(...) in eval at all? Is the result of the replace a valid JavaScript statement or expression? What do you see the purpose of eval as?

also what (informally) are you trying to achieve with the replace? Are you really trying to delete from the start of each line constructs like 

<?anything anything?>anything...<?anything?> followed by spaces, but not at all if not followed by spaces?

I don't know JavScript very well and I am still learning, but I couldn't help but notice the following (please excuse if my observations are too rookie):

I am unsure why these variables are declared like this:

1)   In the  line below, it seems like a variable is missing a replacement function to search for the desired string (but I may be wrong)

• var strData = util.stringFromStream(myXMLFile);

You may have come accross this article by ACP Thom Parker: Text matching with regular expressions using JavaScript 

Also see the example on Page 20 of the Acrobat JS Developer Guide , "Debugging with the JavaScript Console".

2)   And in this line what is the use of  ,""  at the end ?

• var xmlData = eval(strData.replace(/^\<\?.*\?\>\s*/,""));

See also JavaScript™ for Acrobat® API Reference util methods for the following:

• getDataObjectContents
  streamFromString
  stringFromStream

3-)   Last, this variable:

• var nLen = xmlData.child("Branch").length();

Shouldn't it be: var nLen = xmlData.child("Branch").length;  without the "()" ?

Again, please excuse if my observations are not up to par with your JavaScript knowledge or the experts of these support forums.
