    Scanning a document for tags

    i'm using this code to scan a document for the <script and </script> tags, I'm trying to copy each occurance of javascript from a html file and past is into a seperate edit.
    Code:
              szJava = NULL;
              szBuffer[len] = '\0';
              if(szJava = strstr(szBuffer,"<script"))
              {
                szRemain = strstr(szBuffer,"</script>");
                strcpy(szRemain, szBuffer);
                *szRemain = '\0';
                SetWindowText(hJavaSource,szJava);
              }
              while(szJava != NULL)
              {
                szJava = NULL;
                if(szJava = strstr(szBuffer,"<script"))
                {
                  szBuffer[strlen(szBuffer)] = '\0';
                  szRemain = strstr(szBuffer,"</script>");
                  strcpy(szRemain, szBuffer);
                  *szRemain = '\0';
                  AddWindowText(hJavaSource,szJava);
                }
              }
    if i only use the first part of this, the section not in the while loop it works fine but only finds the first occurance of the script tag. but once i added the while loop in it, it crashes with an Access violation message. is there anything wrong with the code or a better way to do this?

    >>strcpy(szRemain, szBuffer);
    Should be szBuffer = szRemain;

    You replaced both instances of it? Another thing that might crash it is if they have <script> and </Script>.
