Manipulating a string

[opencombatclan]

Hi all,

I have a HTML page and php page that captures the HTML pages content.

The Html page contains a time table, lets say it contains:

<TABLE><TR><TD width="33%" nowrap=1><font size="2" face="Arial">
en
</font> </TD>
<TD width="33%" nowrap=1><font size="2" face="Arial">
<i>103
</i></font> </TD>
<TD width="33%" nowrap=1><font size="2" face="Arial">
<B>CBY</B>
</font> </TD>
</TR></TABLE></TD>
<TD align=center nowrap=1 bgcolor="#FFFF00" ><TABLE><TR><TD width="33%" bgcolor="#FFFF00"  nowrap=1><font size="2" face="Arial" color="#000000">
te7.
</font> </TD>
<TD width="33%" bgcolor="#FFFF00"  nowrap=1><font size="2" face="Arial" color="#000000">
<i>007
</i></font> </TD>
<TD width="33%" bgcolor="#FFFF00"  nowrap=1><font size="2" face="Arial" color="#000000">
<B>KUY</B>
</font> </TD>
</TR><TR><TD width="33%" nowrap=1><font size="2" face="Arial">
bi7
</font> </TD>
<TD width="33%" nowrap=1><font size="2" face="Arial">
<i>011
</i></font> </TD>
<TD width="33%" nowrap=1><font size="2" face="Arial">
STU
</font> </TD>
</TR>

 

I want to personalize the time table, and i made a php script that give you sevral options.

For example i want to remove "bi7" (as shown in html code) but bi7 is room 011 from teacher: STU

Lets say i dont need bi7 in my time table, so i want my script to remove it.

 

I got the complete Html page (with table) in my $data var.

 

And i created a option to choose, lets say if its set to 1 you need bi7, and if its set to 0 you want bi7 to be removed from your timtable.

 

But when you remove bi7, also the teacher (STU) and the room (001) needs to be removed.

Since the rooms are always different the PHP code needs to be smart.

 

i taught of:

• Let the PHP code search for: "bi7"
  
• When its there it makes a selection from the nearest <tr> till the nearest </tr> (its <tr> data bi7 data </tr>)
  
• Then it replaces that selection by <!-- removed --> or so
  

 

So when i for example: echo $data, and i choosed to delete bi7

I will get the output:

<TABLE><TR><TD width="33%" nowrap=1><font size="2" face="Arial">
en
</font> </TD>
<TD width="33%" nowrap=1><font size="2" face="Arial">
<i>103
</i></font> </TD>
<TD width="33%" nowrap=1><font size="2" face="Arial">
<B>CBY</B>
</font> </TD>
</TR></TABLE></TD>
<TD align=center nowrap=1 bgcolor="#FFFF00" ><TABLE><TR><TD width="33%" bgcolor="#FFFF00"  nowrap=1><font size="2" face="Arial" color="#000000">
te7.
</font> </TD>
<TD width="33%" bgcolor="#FFFF00"  nowrap=1><font size="2" face="Arial" color="#000000">
<i>007
</i></font> </TD>
<TD width="33%" bgcolor="#FFFF00"  nowrap=1><font size="2" face="Arial" color="#000000">
<B>KUY</B>
</font> </TD>
</TR>
<!-- removed -->

 

I really hope my big idea is clear, and i really need it to work, but i dont know how to delete the specific selection (as i describled above)

 

Please help me out,

 

yours faithfully,

steven

How about parsing the table into a data structure, modifying the structure, then dumping the structure back into a table format?

[opencombatclan]

Hmm, maybe a good idea, but how?

 

i really dont have a single idea of how to do it.

 

Can you help me out?

(or someone else?)

That's if you could get it to parse successfully, but with /TABLE tags in the middle of the cells, I don't hold out much hope.
