Html Parser

[ragdog]

Hi

I have a question to a html parser example or idea!

how I can get the string "Welcome username" and this date "12.08.2008 13:58" and show in a messagesbox?


here is a snipped from the html file:

Code Select Expand


<tr>
<td class="row2" width="100%">
<table style="border: 1px solid rgb(224, 224, 224);" cellpadding="2" cellspacing="0" width="100%">

                <tbody><tr>
                          <td style="text-align: center;" align="center" width="100%">
                                Welcome Username
                    </td>
                            </tr>
                <tr>
                    <td style="text-align: center;" align="center" width="100%">
                                <div align="center"><img src="index.php-Dateien/photo5019.jpg" alt="" border="0" height="48" width="64"></div>
                    </td>
                </tr>
                <tr>
                    <td style="text-align: center;" align="center" width="100%">
                                <span style="color: red; font-weight: bold;">Last visited:</span>
                    </td>
                </tr>
                <tr>
                    <td style="text-align: center;" id="tdblock" align="center" width="100%">
                                12.08.2008
                    </td>
                </tr>
               
                <tr>
                    <td align="left" width="100%">


Can you help me please

I have not made any great efort to parse HTML but it looks like a byte scanner that is geared to scan for opening and closing angle brackets "< & >", record the data within the tags and match opening and closing tags. Now what will make that fun is the way HTML allows multiple forms within a pair of angle brackets.

If you are after a crude and simple method, try a library module in the masm32 library that strips out "<" and content and ">" and what you have left appears to be what you want from the text.

StripRangeI proc lpszSource:DWORD,lpszDest:DWORD,stByte:BYTE,enByte:BYTE

You can try regular expression although it's not the best way.

the regular expression

Code Select Expand


<tr>[\s]*\r\n[\s]*<td [^>]*>[\s]*\r\n[\s]*([\w ]*)[\s]*\r\n[\s]*</td>[\s]*\r\n[\s]*</tr>

matchs

Code Select Expand


<tr>
                          <td style="text-align: center;" align="center" width="100%">
                                Welcome Username
                    </td>
                            </tr>

and the first match is "Welcome Username"

Here I write a simple code,and you can download the perl regular expression lib from here.
