Regex problem?

[mark103]

Hi guys,

I need your help, I am using C++/CLI to code my program. I have got a problem with the regex pattern. I couldn't be able to extract the hyperlink from my php page while I find the matches pattern that I selected on the listview items.

Code:

private: System::Void Button1_Click(System::Object^  sender, System::EventArgs^  e) {


             for each (ListViewItem ^item in this->listView1->CheckedItems)
             {
                 try
                 {
                     String ^URL1 = "http://www.mysite.com/link.php?user=tester";
                      HttpWebRequest ^request1 = safe_cast<HttpWebRequest^>(WebRequest::Create(URL1));
                      HttpWebResponse ^response1 = safe_cast<HttpWebResponse^>(request1->GetResponse());
                      StreamReader ^reader1 = gcnew StreamReader(response1->GetResponseStream());
                      String ^str1 = reader1->ReadToEnd();
                      String ^pattern1 = item->Text + "(<p id='images'>(.*?)</p>)";
                      MatchCollection ^matches1 = Regex::Matches(str1, pattern1);
                      Match ^m1 = Regex::Match(str1, pattern1);


                     for each (Match ^x1 in matches1)
                     {
                         array<String^> ^StrArr1 = x1->Value->ToString()->Split();
                         String ^test = (URL1 + x1->Value->ToString());
                         MessageBox::Show(test);
                     }
                 }
                 catch (Exception ^ex)
                 {

                 }
             }

         }

I am definitely sure that the html tags has the correct tags name.

However, I have put the breakpoint in this line:

Match ^m1 = Regex::Match(str1, pattern1);

I can see the value for pattern1 so here it is:

"my strings 1<p id='images'>(.*?)</p>"

It have found the matches with the html tag, but it doesn't extract the id. So here's the html tags:

<p id="images"> <a href="images.php?id=1">Images</a>  

Do anyone know how I can extract the id in the images tags from the html source?

Any idea how I can do this?

Thanks in advance.
