Relative to absolute paths in HTML (asp.net) -

-

i need create newsletters url. next:

  1. create webclient;
  2. use webclient's method downloaddata source of page in byte array;
  3. get string source-html byte array , set newsletter content.

but have troubles paths. elements' sources relative (/img/welcome.png) need absolute (http://www.mysite.com/img/welcome.png).

how can this?

best regards, alex.

one of possible ways resolve task use htmlagilitypack library.

some example (fix links):

webclient client = new webclient(); byte[] requesthtml = client.downloaddata(sourceurl); string sourcehtml = new utf8encoding().getstring(requesthtml);  htmldocument htmldoc = new htmldocument(); htmldoc.loadhtml(sourcehtml);  foreach (htmlnode link in htmldoc.documentnode.selectnodes("//a[@href]")) {     if (!string.isnullorempty(link.attributes["href"].value))     {         htmlattribute att = link.attributes["href"];         att.value = this.absoluteurlbyrelative(att.value);     } }

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
