c# - How to remove nodes using HTML agility pack and XPath so as to clean the HTML page -

-

i need extract text webpages related business news. html page follows..

<html>       <body>     <div>     <p> <span>desired content - 1</span></p>     <p> <span>desired content - 2</span></p>     <p> <span>desired content - 3</span></p>     </div>   </body> </html>"

i have sample stored in string can take me desired content -1 directly, can collect content. need collect desired content -2 , 3.

for tried current location i.e in span node of desired content -1 used parentof , moved external node i.e para node , got content need entire desired content in div. how it? might ask me go div directly using parentof.parentof.span. specific example, need general idea.

mostly news articles have desired content in division , go directly nested inner node of division. need come out of inner nodes till encounter division , innertext.

i using xpath , htmlagilitypack.

xpath using - 

variable = doc.documentnode.selectsinglenode("//*[contains(text(),'" + searchdata + "')]").parentnode.parentnode.innertext;

here "searchdata" variable holding sample of desired content -1 used searching node having news in entire body of webpage.

what thinking clean webpages , have main tags html, body, tables, division , paragraphs no spans , other formating elements. other website might use spans instead of divs not sure how implement requirement.

basic requirement extract news content different webpages(almost 250 different websites). can not code specific each webpage..i need generic method.

any ideas appreciated. thank you.

this xpath expression selects innermost div element $searchdata variable reference value part of string value.

//div[contains(.,$searchdata)]      [not(.//div[contains(.,$searchdata)])]

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
