1.让数据与显示分离

test.xml 数据:

test title

test content

banner

sidebar

main body

end of the page

test.xslt 模板:

test

]]>

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:
