Use PHP to dynamically generate xml files and extract data from xml files and convert them into html small programs_PHP tutorial

这个东东搞了我一天。。。可是到最后发现却无法实现自己想像中的那种效果。。。真是可惜。。。看来php(做为现在的主流开发语言)对xml(标准化越来越近了)还需要加强。。。如果哪位对此有研究。欢迎来信探讨。。。

首先建表：
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),
);

然后。。。这段是从MySQL(和PHP搭配之最佳组合)里取数据转化成xml(标准化越来越近了)的源代码：
$connect_id=MySQL(和PHP搭配之最佳组合)_connect("localhost","root","");
MySQL(和PHP搭配之最佳组合)_select_db("bbs",$connect_id);
$query="select * from books order by bookid";
$rs=MySQL(和PHP搭配之最佳组合)_query($query,$connect_id);
$numfields=MySQL(和PHP搭配之最佳组合)_num_fields($rs);
$xml(标准化越来越近了)file="(标准化越来越近了) version="1.0" encoding="GB2312"?>n";
$xml(标准化越来越近了)file.="n";

while($row=MySQL(和PHP搭配之最佳组合)_fetch_array($rs)){
for($i=0;$i<$numfields;$i ){
$fieldname=MySQL(和PHP搭配之最佳组合)_field_name($rs,$i);
$xml(标准化越来越近了)file.="<" . $fieldname . ">" . $row[$i] . "n";
}
}
MySQL(和PHP搭配之最佳组合)_free_result($rs);
MySQL(和PHP搭配之最佳组合)_close($connect_id);
$xml(标准化越来越近了)file.="n";
$fp=fopen("xml(标准化越来越近了)doc/xml(标准化越来越近了)doc.xml(标准化越来越近了)","w");
if(fwrite($fp,$xml(标准化越来越近了)file)){
echo "写入文件成功!";
}
else{
echo "写入文件失败!";
}
?>

这段是从xml(标准化越来越近了)里取数据转化成HTML的源代码。。。
class xml(标准化越来越近了){
var $parser;

function xml(标准化越来越近了)(){
$this->parser = xml(标准化越来越近了)_parser_create();
xml(标准化越来越近了)_set_object($this->parser,&$this);
xml(标准化越来越近了)_set_element_handler($this->parser,"tag_on","tag_off");
xml(标准化越来越近了)_set_character_data_handler($this->parser,"cdata");
}

function parse($data){
xml(标准化越来越近了)_parse($this->parser,$data);
}

function tag_on($parser,$tag,$attributes){
if(xml(标准化越来越近了)_get_current_line_number($parser)==2){
echo "" . $tag . "";
}
else{
switch ((xml(标准化越来越近了)_get_current_line_number($parser)-2)%6){
case 0:
echo "下载";
break;
case 1:
echo "ID号";
break;
case 2:
echo "书名";
break;
case 3:
echo "作者";
break;
case 4:
echo "出版社";
break;
case 5:
echo "出版日期";
break;
}
}
}

function cdata($parser,$cdata){
echo $cdata;
}

function tag_off($parser,$tag){
echo "n";
}
}

$xml(Standardization is getting closer)_parser = new xml(Standardization is getting closer)();
$xml(Standardization Getting closer)filename="xml(Standardization is getting closer)doc/xml(Standardization is getting closer)doc.xml (Standardization is getting closer)";
$fp=fopen($xml(Standardization is getting closer)filename,"r");
$xml(Standardization is getting closer)data=fread($fp,filesize($xml(Standardization is getting closer)filename));
?>

$xml(Standardization is getting closer)_parser-> ;parse($xml(Standardization is getting closer)data);
?>

In fact, you should be able to see it. . This example is a failure. . . Because the effect is not big. . You simply can't get what you want. . . well. . . bitter. . . .
