Small programs that use php to dynamically generate xml files and extract data from xml files into html

Source: Internet
Author: User

This stuff took me a day... However, at the end, I found that I could not achieve the effect I imagined... It's a pity... It seems that php (as the mainstream development language) is more and more important to xml (standardization is getting closer and closer... If anyone has research on this. Thank you for writing to us...

Create a table first:
Create table books (
Bookid int (4) not null auto_increment,
Bookname varchar (100) not null,
Bookauth varchar (50) not null,
Bookpublisher varchar (50) not null,
Bookpubdate datetime not null,
Bookurl varchar (50) not null,
KEY bookid (bookid ),
);

Then... This section is the source code for converting data from MySQL (the best combination with PHP) to xml (standardization is getting closer and closer:
<?
$ Connect_id = MySQL (the best combination with PHP) _ connect ("localhost", "root ","");
MySQL (best combination with PHP) _ select_db ("bbs", $ connect_id );
$ Query = "select * from books order by bookid ";
$ Rs = MySQL (the best combination with PHP) _ query ($ query, $ connect_id );
$ Numfields = MySQL (the best combination with PHP) _ num_fields ($ rs );
$ Xml (standardization is getting closer and closer) file = "<? Xml (standardization is getting closer and closer) version = "1.0" encoding = "GB2312"?> N ";
$ Xml (standardization is getting closer and closer) file. = "<books> n ";

While ($ row = MySQL (the best combination with PHP) _ fetch_array ($ rs )){
For ($ I = 0; $ I <$ numfields; $ I ){
$ Fieldname = MySQL (the best combination with PHP) _ field_name ($ rs, $ I );
$ Xml (standardization is getting closer and closer) file. = "<". $ fieldname. "> ". $ row [$ I]. "</". $ fieldname. "> n ";
}
}
MySQL (the best combination with PHP) _ free_result ($ rs );
MySQL (the best combination with PHP) _ close ($ connect_id );
$ Xml (standardization is getting closer and closer) file. = "</books> n ";
$ Fp = fopen ("xml (standardization is getting closer and closer) doc/xml (standardization is getting closer and closer) doc. xml (standardization is getting closer and closer)", "w ");
If (fwrite ($ fp, $ xml (standardization is getting closer and closer) file )){
Echo "file written! ";
}
Else {
Echo "failed to write file! ";
}
?>

This section is the source code for converting data from xml (standardization is getting closer and closer) to HTML...
<?
Class xml (standardization is getting closer and closer ){
Var $ parser;

Function xml (standardization is getting closer and closer )(){
$ This-> parser = xml (standardization is getting closer and closer) _ parser_create ();

Xml (standardization is getting closer and closer) _ set_character_data_handler ($ this-> parser, "cdata ");
}

Function parse ($ data ){
Xml (standardization is getting closer and closer) _ parse ($ this-> parser, $ data );
}

Function tag_on ($ parser, $ tag, $ attributes ){
If (xml (standardization is getting closer and closer) _ get_current_line_number ($ parser) = 2 ){
Echo "<tr> <td colspan =" 2 "align =" center ">". $ tag. "</td> ";
}
Else {
Switch (xml (standardization is getting closer and closer) _ get_current_line_number ($ parser)-2) % 6 ){
Case 0:
Echo "<tr> <td> download <td> ";
Break;
Case 1:

Break;
Case 2:

Break;
Case 3:

Case 4:

Case 5:

Break;
}
}
}

Function cdata ($ parser, $ cdata ){
Echo $ cdata;
}

Function tag_off ($ parser, $ tag ){
Echo "n ";
}
}

$ Xml (standardization is getting closer and closer) _ parser = new xml (standardization is getting closer and closer )();
$ Xml (standardization is getting closer and closer) filename = "xml (standardization is getting closer and closer) doc/xml (standardization is getting closer and closer) doc. xml (standardization is getting closer and closer )";
$ Fp = fopen ($ xml (standardization is getting closer and closer) filename, "r ");
$ Xml (standardization is getting closer and closer) data = fread ($ fp, filesize ($ xml (standardization is getting closer and closer) filename ));
?>
<HTML> <Body>
<Table border = "0" cellspacing = "1" cellpadding = "2" width = "80%" bgcolor = "# b0d8fF" align = "center">
<?
$ Xml (standardization is getting closer and closer) _ parser-> parse ($ xml (standardization is getting closer and closer) data );
?>
</Table>

Actually, you can see that .. This example is a failure... Because it is not very effective .. You cannot get what you want... Alas... Bitter ....
