You can check my bookmarklets as example. There are some features: 1. It is use post request, so any size of data can be send to server 2. It is use user selection from page 3. It is extract page text content using boilerpipe library.

<a class="button" href="javascript:function post_to_url(path,params,method){method=method||'post';var form=document.createElement('form');form.setAttribute('method', method);form.setAttribute('action',path);form.setAttribute('accept-charset','UTF-8');for(var key in params){var hiddenField=document.createElement('input');hiddenField.setAttribute('type','hidden');hiddenField.setAttribute('name',key);hiddenField.setAttribute('value',params[key]);form.appendChild(hiddenField);}document.body.appendChild(form); form.submit();};var t=((window.getSelection&&window.getSelection())||(document.getSelection&&document.getSelection())||(document.selection&&document.selection.createRange&&document.selection.createRange().text)||location.href);if(t=='')t=location.href;post_to_url('http://g-calendar.appspot.com/analyze/analyze', {withKeywords:'true', message:t, sumSize:5, return_type:'list', title:document.title, url:location.href}, 'post')">
    Summarise
</a>

You can get the tagname with element.tagName, and any attribute of that tag with element.getAttribute('attributename'). Would that get you the data you are trying to get?

If not, can you give us an example of the data you are trying to get?
