Question

I want to retrieve some values from a webpage using Pattern & Matcher

<form name="loginForm"  id="loginForm"  method="post" onsubmit="ScrollUp(60);return validateLoginForm();" 
                 enctype="multipart/form-data" action="/login.php">
                 <input type="hidden" name="Rpidci" value="">
                <div class="last_box">
                    <div class="second_box_heading_panel">
                        <h1>Existing users  - 
                            <span> Login here</span>
                        </h1>
                    </div>
                    <div class="second_box_form_panel">
                        <div class="error-msg">
                                                        </div>
                        <div class="name_form_panel">
                            <div class="name">User Name
                            </div>
                            <div class="name_text_field">
                                <input name="sHZnGSgdzmIJoKWOCHmYez" type="text" class="existing_user round_four" id="sHZnGSgdzmIJoKWOCHmYez" maxlength="10" value=""/>
                            </div>
                        </div>
                        <div class="name_form_panel">
                            <div class="name">Password 
                            </div>
                            <div class="name_text_field"><input name="AWrPDfe" type="password" class="existing_user round_four" id="AWrPDfe" maxlength = "20"
                            value=""/>
                            </div>
                        </div>


                              <div class="login_btn"><a href="javascript:void(0);" onclick="javascript:ScrollUp(70);return validateLoginForm();"><img src="images/login_btn.png" title="login here" /></a></div>
                            </div>
                            </div>
                      <div class="name_form_panel"></div>

                                                        </div> 

                    </div>
              </form>

I want to retrieve values of this two fields

<input name="sHZnGSgdzmIJoKWOCHmYez" type="text" class="existing_user round_four" id="sHZnGSgdzmIJoKWOCHmYez" maxlength="10" value=""/>

&

<input name="AWrPDfe" type="password" class="existing_user round_four" id="AWrPDfe" maxlength = "20" value=""/>

I tried several times but failed in getting the output. Please help.

EDIT:

The code I tried is as below: (not the same as I wrote initially as I was frustrated and messed it up very much)

Matcher matcher = Pattern.compile("<form name=\"loginForm\" .+ method=\"post\" .+ action=\"/login.php\">\\s*<input[^>]+>\\s*<input[^>]+>\\s*").matcher(loginResp);

        String[] strArr = matcher.group(0).split("<input");
        String str1 = "";
        String str2 = "";
        String str3 = "";
        String str4 = "";

        Pattern localPattern = Pattern.compile(" name=\"([^\\s]+)\" type=\"text\" id=\"([^\\s]+)\" value=\"([^\\s]+)\" />");
        Matcher localMatcher2 = localPattern.matcher(strArr[3]);
        if (localMatcher2.find()) {
            str1 = localMatcher2.group(1);
            echo("STR1 " + str1);
            str2 = localMatcher2.group(3);
            echo("STR2 " + str2);
        }

As ever, I would recommend using an HTML parser such as JTidy or JSoup. You can’t do this reliably using regular expressions and an HTML parser is a much easier solution.
