如何理解 Web 语义化？ - 知乎 https://www.zhihu.com/question/20455165

“

当然这里又回到一开始的语义网了，因为人们的查询不光是字面匹配，人们希望使用更聪明的搜索引擎。那么搜索引擎应该知道用户的意图，这不是什么人工智能，而是一些基于统计的算法。但是这些算法都和语义网中的一些东西有相关性，因为人们需要得到数据，并且找到这些数据的本体，通过一些预先定义好的本体之间的关系进行逻辑推演（目前都是写死的算法，而没有使用语义网里面的推演系统）。也就是说这个模型从概念上和语义网相似，但是由于技术上还不太可行，所以走了其它的路。不过从理解文本的这个地方来说，所有的现代搜索引擎都有这方面的逻辑。它希望把搜集到的文本描述成一种可以推演的数据，在语义网里面描述这些数据的方式之一是RDF。RDF基于XML，而HTML中的XHTML是一种XML。通过HTML的attribute储存语义网数据叫RDFa（Resource Description Framework – in – attributes），这就把HTML/XHTML和语义网技术拉到了一起，当然光表示数据只是语义网的一部分。

What is XML?

The XML language is a way to structure data for sharing across websites.

Several web technologies like RSS Feeds and Podcasts are written in XML.

XML is easy to create. It looks a lot like HTML, except that you make up your own tags.

What is an XML Parser?

Tree-Based Parsers

Tree-based parsers holds the entire document in Memory and transforms the XML document into a Tree structure. It analyzes the whole document, and provides access to the Tree elements (DOM).

This type of parser is a better option for smaller XML documents, but not for large XML document as it causes major performance issues.

Example of tree-based parsers:

SimpleXML
DOM

Event-Based Parsers

Event-based parsers do not hold the entire document in Memory, instead, they read in one node at a time and allow you to interact with in real time. Once you move onto the next node, the old one is thrown away.

This type of parser is well suited for large XML documents. It parses faster and consumes less memory.

Example of event-based parsers:

XMLReader
XML Expat Parser

基于树的解析器：这种解析器把 XML 文档转换为树型结构。它分析整篇文档，并提供了 API 来访问树种的元素，例如文档对象模型 (DOM)。
基于事件的解析器：将 XML 文档视为一系列的事件。当某个具体的事件发生时，解析器会调用函数来处理。

SimpleXML is a PHP extension that allows us to easily manipulate and get XML data.

The SimpleXML Parser

SimpleXML is a tree-based parser.

SimpleXML provides an easy way of getting an element's name, attributes and textual content if you know the XML document's structure or layout.

SimpleXML turns an XML document into a data structure you can iterate through like a collection of arrays and objects.

Compared to DOM or the Expat parser, SimpleXML takes a fewer lines of code to read text data from an element.

Installation

As of PHP 5, the SimpleXML functions are part of the PHP core. No installation is required to use these functions.

PHP SimpleXML - Read From String

The PHP simplexml_load_string() function is used to read XML data from a string.

The example below shows how to use the simplexml_load_string() function to read XML data from a string:

CODE

$myXMLData =

    "<?xml version='1.0' encoding='UTF-8'?>

<note>

<to>Tove</to>

<from>Jani</from>

<heading>Reminder</heading>

<body>Don't forget me this weekend!</body>

</note>";

$xml = simplexml_load_string($myXMLData) or die("Error: Cannot create object");

print_r($xml);

SimpleXMLElement Object ( [to] => Tove [from] => Jani [heading] => Reminder [body] => Don't forget me this weekend! )

Error Handling Tip: Use the libxml functionality to retrieve all XML errors when loading the document and then iterate over the errors. The following example tries to load a broken XML string:

CODE

libxml_use_internal_errors(true);

$myXMLData =

    "<?xml version='1.0' encoding='UTF-8'?>

<document>

<user>John Doe</wronguser>

<email>john@example.com</wrongemail>

</document>";

$xml = simplexml_load_string($myXMLData);

if ($xml === false) {

    echo "Failed loading XML: ";

    foreach (libxml_get_errors() as $error) {

        echo "<br>", $error->message;

    }

} else {

    print_r($xml);

}

Failed loading XML:
Opening and ending tag mismatch: user line 3 and wronguser
Opening and ending tag mismatch: email line 4 and wrongemail

PHP SimpleXML - Read From File

The PHP simplexml_load_file() function is used to read XML data from a file.

Assume we have an XML file called "note.xml", that looks like this:

The example below shows how to use the simplexml_load_file() function to read XML data from a file:

<?xml version="1.0" encoding="UTF-8"?>

<note>

  <to>Tove</to>

  <from>Jani</from>

  <heading>Reminder</heading>

  <body>Don't forget me this weekend!</body>

</note>

$xml=simplexml_load_file("note.xml") or die("Error: Cannot create object");

print_r($xml);

SimpleXMLElement Object ( [to] => Tove [from] => Jani [heading] => Reminder [body] => Don't forget me this weekend! )

PHP SimpleXML - Get Node/Attribute Values

SimpleXML is a PHP extension that allows us to easily manipulate and get XML data.

PHP SimpleXML - Get Node Values

Get the node values from the "note.xml" file:

（无<?xml version="1.0" encoding="utf-8"?>）

<note>

    <script/>

    <to>Tove</to>

    <from>Jani</from>

    <heading>Reminder</heading>

    <body>Don't forget me this weekend!</body>

</note>

Get the node values from the "note.xml" file:

<?php

$xml = simplexml_load_file("note.xml") or die("Error: Cannot create object");

echo $xml->to . "<br>";

echo $xml->from . "<br>";

echo $xml->heading . "<br>";

echo $xml->body;

Tove
Jani
Reminder
Don't forget me this weekend!

Assume we have an XML file called "books.xml", that looks like this:

<?xml version="1.0" encoding="utf-8"?>

<bookstore>

    <book category="COOKING">

        <title lang="en">Everyday Italian</title>

        <author>Giada De Laurentiis</author>

        <price>39.95</price>

    </book>

</bookstore>

PHP SimpleXML - Get Node Values of Specific Elements

The following example gets the node value of the <title> element in the first and second <book> elements in the "books.xml" file:

<?php

$xml = simplexml_load_file("books.xml") or die("Error: Cannot create object");

echo $xml->book[0]->title . "<br>";

echo $xml->book[1]->title;

当books.xml路径下不存在时

Everyday Italian
Harry Potter

PHP SimpleXML - Get Node Values - Loop

The following example loops through all the <book> elements in the "books.xml" file, and gets the node values of the <title>, <author>, <year>, and <price> elements:

<?php

$xml = simplexml_load_file("books.xml") or die("Error: Cannot create object");

foreach ($xml->children() as $books) {

    echo $books->title . ", ";

    echo $books->author . ", ";

    echo $books->year . ", ";

    echo $books->price . "<br>";

}

Everyday Italian, Giada De Laurentiis, 2005, 30.00
Harry Potter, J K. Rowling, 2005, 29.99
XQuery Kick Start, James McGovern, 2003, 49.99
Learning XML, Erik T. Ray, 2003, 39.95

PHP SimpleXML - Get Attribute Values

The following example gets the attribute value of the "category" attribute of the first <book> element and the attribute value of the "lang" attribute of the <title> element in the second <book> element:

<?php

$xml = simplexml_load_file("books.xml") or die("Error: Cannot create object");

echo $xml->book[0]['category'] . "<br>";

echo $xml->book[1]->title['lang'];

Initializing the XML Expat Parser

We want to initialize the XML Expat Parser in PHP, define some handlers for different XML events, and then parse the XML file.

<?php

// Initialize the XML parser

$parser = xml_parser_create();

// Function to use at the start of an element

function start($parser, $element_name, $element_attrs)

{

    switch ($element_name) {

        case "NOTE":

            echo "-- Note --<br>";

            break;

        case "TO":

            echo "To: ";

            break;

        case "FROM":

            echo "From: ";

            break;

        case "HEADING":

            echo "Heading: ";

            break;

        case "BODY":

            echo "Message: ";

    }

}

// Function to use at the end of an element

function stop($parser, $element_name)

{

    echo "<br>";

}

// Function to use when finding character data

function char($parser, $data)

{

    echo $data;

}

// Specify element handler

xml_set_element_handler($parser, "start", "stop");

// Specify data handler

xml_set_character_data_handler($parser, "char");

// Open XML file

$fp = fopen("note.xml", "r");

// Read data

while ($data = fread($fp, 4096)) {

    xml_parse($parser, $data, feof($fp)) or

    die (sprintf("XML Error: %s at line %d",

        xml_error_string(xml_get_error_code($parser)),

        xml_get_current_line_number($parser)));

}

// Free the XML parser

xml_parser_free($parser);

-- Note --
To: Tove
From: Jani
Heading: Reminder
Message: Don't forget me this weekend!

Example explained:

Initialize the XML parser with the xml_parser_create() function
Create functions to use with the different event handlers
Add the xml_set_element_handler() function to specify which function will be executed when the parser encounters the opening and closing tags
Add the xml_set_character_data_handler() function to specify which function will execute when the parser encounters character data
Parse the file "note.xml" with the xml_parse() function
In case of an error, add xml_error_string() function to convert an XML error to a textual description
Call the xml_parser_free() function to release the memory allocated with the xml_parser_create() function

<?php

$xmlDoc = new DOMDocument();

$xmlDoc->load("note.xml");

print $xmlDoc->saveXML();

Tove Jani Reminder Don't forget me this weekend!

<?php

$xmlDoc = new DOMDocument();

$xmlDoc->load("note.xml");

$x = $xmlDoc->documentElement;

foreach ($x->childNodes AS $item) {

    print $item->nodeName . " = " . $item->nodeValue . "<br>";

}

#text =

XML设计用来传送及携带数据信息，不用来表现或展示数据，HTML语言则用来表现数据，所以XML用途的焦点是它说明数据是什么，以及携带数据信息。

丰富文件（Rich Documents）- 自定文件描述并使其更丰富
- 属于文件为主的XML技术应用
- 标记是用来定义一份资料应该如何呈现
元数据（Metadata）- 描述其它文件或网络资讯
- 属于资料为主的XML技术应用
- 标记是用来说明一份资料的意义
配置文档（Configuration Files）- 描述软件设置的参数

XSL 指扩展样式表语言（EXtensible Stylesheet Language）。

万维网联盟开始发展 XSL 的起因是由于对基于 XML 的样式表语言的需求。

http://www.w3school.com.cn/xsl/xsl_languages.asp

XSL

它起始于 XSL，结束于 XSLT、XPath 以及 XSL-FO。

起始于 XSL

XSL 指扩展样式表语言（EXtensible Stylesheet Language）。

万维网联盟 (W3C) 开始发展 XSL 的原因是：存在着对于基于 XML 的样式表语言的需求。

CSS = HTML 样式表

HTML 使用预先定义的标签，标签的意义很容易被理解。

HTML 元素中的 <table> 元素定义表格 - 并且浏览器清楚如何显示它。

向 HTML 元素添加样式是很容易的。通过 CSS，很容易告知浏览器用特定的字体或颜色显示一个元素。

XSL = XML 样式表

XML 不使用预先定义的标签（我们可以使用任何喜欢的标签名），并且这些标签的意义并不都那么容易被理解。

<table> 元素意味着一个 HTML 表格，一件家具，或是别的什么东西 - 浏览器不清楚如何显示它。

XSL 可描述如何来显示 XML 文档！

XSL - 不仅仅是样式表语言

XSL 包括三部分：

XSLT

一种用于转换 XML 文档的语言。

XPath

一种用于在 XML 文档中导航的语言。

XSL-FO

一种用于格式化 XML 文档的语言。

XSLT 是一种用于将 XML 文档转换为 XHTML 文档或其他 XML 文档的语言。

XPath 是一种用于在 XML 文档中进行导航的语言。
