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里取数据转化成XML的源代码：
<?
$connect_id=mysql_connect("localhost","root","");
mysql_select_db("bbs",$connect_id);
$query="select * from books order by bookid";
$rs=mysql_query($query,$connect_id);
$numfields=mysql_num_fields($rs);
$xmlfile="<?xml version="1.0" encoding="GB2312"?>n";
$xmlfile.="<books>n";
while($row=mysql_fetch_array($rs)){
for($i=0;$i<$numfields;$i++){
$fieldname=mysql_field_name($rs,$i);
$xmlfile.="<" . $fieldname . ">" . $row[$i] . "</" . $fieldname . ">n";
}
}
mysql_free_result($rs);
mysql_close($connect_id);
$xmlfile.="</books>n";
$fp=fopen("xmldoc/xmldoc.xml","w");
if(fwrite($fp,$xmlfile)){
echo "写入文件成功!";
}
else{
echo "写入文件失败!";
}
?>
这段是从XML里取数据转化成HTML的源代码。。。
<?
class xml{
var $parser;
function xml(){
$this->parser = xml_parser_create();
xml_set_object($this->parser,&$this);
xml_set_element_handler($this->parser,"tag_on","tag_off");
xml_set_character_data_handler($this->parser,"cdata");
}
function parse($data){
xml_parse($this->parser,$data);
}
function tag_on($parser,$tag,$attributes){
if(xml_get_current_line_number($parser)==2){
echo "<tr><td colspan="2" align="center">" . $tag . "</td>";
}
else{
switch ((xml_get_current_line_number($parser)-2)%6){
case 0:
echo "<tr><td>下载<td>";
break;
case 1:
echo "<tr><td>ID号<td>";
break;
case 2:
echo "<tr><td>书名<td>";
break;
case 3:
echo "<tr><td>作者<td>";
break;
case 4:
echo "<tr><td>出版社<td>";
break;
case 5:
echo "<tr><td>出版日期<td>";
break;
}
}
}
function cdata($parser,$cdata){
echo $cdata;
}
function tag_off($parser,$tag){
echo "n";
}
}
$xml_parser = new xml();
$xmlfilename="xmldoc/xmldoc.xml";
$fp=fopen($xmlfilename,"r");
$xmldata=fread($fp,filesize($xmlfilename));
?>
<html><head><title>图书信息</title></head>
<body>
<table border="0" cellspacing="1" cellpadding="2" width="80%" bgcolor="<?
$xml_parser->parse($xmldata);
?>
