基于xml+xslt+css+php快速构建可扩展网站

网络整理 - 07-27

1.让数据与显示分离

test.xml 数据:

<xml>
<title>test title</title>
<content>test content</content>
<top>banner</top>
<left>sidebar</left>
<body>main body</body>
<end>end of the page</end>
</xml>

test.xslt 模板:

<?xml version=”1.0″ encoding=”UTF-8″?>
<xsl:stylesheet version=”1.0″ xmlns:xsl=””>
<xsl:output method=”html” encoding=”UTF-8″/>
<xsl:template name=”index” match=”xml”>
<xsl:value-of select=”document(”)/*/xsl:template[@name='DOCTYPE']/node()” disable-output-escaping=”yes”/>
</xsl:template>
<html>
<head>
<meta http-equiv=”Content-Type” content=”text/html; charset=utf-8″/>
<title>test</title>
<link rel=”stylesheet” type=”text/css” href=”test.css” />
</head>
<body>
<div class=”title”><xsl:value-of select=”title”/></div>
<div class=”content”><xsl:value-of select=”content” disable-output-escaping=”yes”/></div>
<div class=”top”><xsl:value-of select=”top”/></div>
<div class=”left”><xsl:value-of select=”left”/></div>
<div class=”body”><xsl:value-of select=”body”/></div>
<div class=”end”><xsl:value-of select=”end”/></div>
</body>
</html>
<xsl:template name=”DOCTYPE”>
<![CDATA[<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">]]>
</xsl:template>
</xsl:stylesheet>

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:

<xml>
<pages>
<page>
<name>test.html</name>
<xmlfile>test.xml</xmlfile>
<xslfile>test.xslt</xslfile>
</page>
</pages>
</xml>

php 代码:

<?php
$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\t$xml\t$xsl\n”;
$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
