Quickly build an scalable website based on xml+xslt+css+php_PHP tutorial

1.让数据与显示分离

 

test.xml 数据:

 

test content

banner

sidebar

main body

end of the page

 

test.xslt 模板:

 

]]>

 

 

2.网页自动生成

 

php 程序读入config文件根据文件中指定的目标文件名 和 数据文件名 以及 模板文件名生成目标页面

 

config 文件:

 

test.html

test.xml

test.xslt

 

php 代码:

 

$xml_file = “../conf/config”;

$name_tag = 0;

$xml_tag = 0;

$xsl_tag = 0;

 

$name = “”;

 

$arr = Array();

 

$i = 0;

 

function startElement($parser_instance, $element_name, $attrs)

{

global $name_tag;

global $xml_tag;

global $xsl_tag;

 

switch($element_name)

{

case “NAME” :

$name_tag = 1;

break;

case “XMLFILE” :

$xml_tag = 1;

break;

case “XSLFILE” :

$xsl_tag = 1;

break;

}

}

 

function characterData($parser_instance, $xml_data)

{

global $arr;

global $name_tag;

global $xml_tag;

global $xsl_tag;

global $name;

 

$xml_data = ltrim($xml_data);

 

if ($xml_data != “”)

{

if ($name_tag == 1)

{

$arr["$xml_data"] = Array();

$name = $xml_data;

$arr["$name"][0] = $name;

$name_tag = 0;

}

 

if ($xml_tag == 1)

{

$arr["$name"][1] = $xml_data;

$xml_tag = 0;

}

 

if ($xsl_tag == 1)

{

$arr["$name"][2] = $xml_data;

$xsl_tag = 0;

}

}

}

 

function endElement($parser_instance, $element_name)

{

 

}

 

function buildHtml($name, $xml, $xsl)

{

echo “$name $xml $xsl ”;

$xslDoc = new DOMDocument();

$xslDoc->load(”$xsl”);

 

$xmlDoc = new DOMDocument();

$xmlDoc->load(”$xml”);

 

$proc = new XSLTProcessor();

$proc->importStylesheet($xslDoc);

$html = $proc->transformToXML($xmlDoc);

 

if (!($filehandler = fopen($name, “w+”)))

{

die(”could not open $name output”);

}

 

fwrite($filehandler, $html);

 

fclose($filehandler);

}

 

$parser = xml_parser_create();

 

xml_set_element_handler($parser, “startElement”, “endElement”);

xml_set_character_data_handler($parser, “characterData”);

 

if (!($filehandler = fopen($xml_file, “r”)))

{

die(”could not open XML input”);

}

 

while ($data = fread($filehandler, 4096))

{

if (!xml_parse($parser, $data, feof($filehandler)))

{

die(sprintf(”XML error: %s at line %d”,

xml_error_string(xml_get_error_code($parser)),

xml_get_current_line_number($parser)));

}

}

 

 

fclose($filehandler);

xml_parser_free($parser);

 

 

 

foreach ($arr as $sub_arr)

{

$i = 0;

foreach ($sub_arr as $obj)

{

if ($i == 0)

{

$name = $obj;

}

 

if ($i == 1)

{

$xml = $obj;

}

 

if ($i == 2)

{

$xsl = $obj;

}

 

$i++;

}

buildHtml($name, $xml, $xsl);

 

}

 

 

?>

 

 

 

3.重新规划整个页面

 

 

这样的分拆式设计可以使页面更灵活,随意修改任何部分都不会影响到其余的块,并且可以不断变换其中的某个块的数据 比如:body.xml 来生成更多新的页面, 特别适合新闻系统或论坛使用

 

top.xml:
