web scraping a problem site

This my Answer to the stackoverflow question: web scraping a problem site:

The website loads the data via ajax. Firebug shows the ajax calls. For the given page, the data is loaded from https://personal.vanguard.com/us/JSP/Funds/VGITab/VGIFundOverviewTabContent.jsf?FundIntExt=INT&FundId=0542

See the corresponding javascript code on the original page:

<script>populator = new Populator({parentId:
inline:fals   e,type:"once"});
