Why would you want to "parse the sm"?

The link you showed and the resulting URL are identical unless the whitespace in the link you showed actually exists:

<a href="MySurvey_SummaryDownload.aspx?sm= yUsTZIyAVJQqSsTu3TSbdT0ZMzs
+fbk0cbSdAOVkNUDY%3d" class="itBtn">
        /MySurvey_SummaryDownload.aspx?sm=yUsTZIyAVJQqSsTu3TSbdT0ZMzsf
+bk0cbSdAOVkNUDY%3d

Anyway, the general rule of thumb when automating things is to compare what your script does against what the reference does. So, compare what Wireshark gets from your browser against what it gets when you use WWW::Mechanize. Also test the site with Javascript disabled.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
