Examples of xml parsing methods in php and xml parsing examples

This document describes in detail the xml Parsing Method in php as an example. Share it with you for your reference. The specific analysis is as follows:

The books. xml file is as follows:

<?xml version="1.0" encoding="ISO-8859-1"?><bookstore> <book category="children"> <title lang="en">Harry Potter</title> <author>J K. Rowling</author> <year>2005</year> <price>29.99</price> </book> <book category="cooking"> <title lang="en">Everyday Italian</title> <author>Giada De Laurentiis</author> <year>2005</year> <price>30.00</price> </book> <book category="web" cover="paperback"> <title lang="en">Learning XML</title> <author>Erik T. Ray</author> <year>2003</year> <price>39.95</price> </book></bookstore>

1. DOM parsing XML

<? Php // create a DOMDocument object $ doc = new DOMDocument (); // load the XML file $ doc-> load ("books. xml "); // get all book tags $ bookDom = $ doc-> getElementsByTagName (" book "); foreach ($ bookDom as $ book) {$ title = $ book-> getElementsByTagName ("title")-> item (0)-> nodeValue; $ author = $ book-> getElementsByTagName ("author ") -> item (0)-> nodeValue; $ year = $ book-> getElementsByTagName ("year")-> item (0)-> nodeValue; $ price = $ book-> getElementsByT AgName ("price")-> item (0)-> nodeValue; echo "title :". $ title. "<br>"; echo "author :". $ author. "<br>"; echo "year :". $ year. "<br>"; echo "price :". $ price. "<br> "; echo "********************************** <br> ";}?>

2. xml_parse_into_struct

Create a parser, parse the xml data to the array, release the parser, and then extract the desired value from the array.

<? Php // read xml file $ file = "books. xml "; $ data = file_get_contents ($ file); // create a parser $ parser = xml_parser_create (); // Parse XML data to the array xml_parse_into_struct ($ parser, $ data, $ vals, $ index); // release the parser xml_parser_free ($ parser); // array Processing $ arr = array (); $ t = 0; foreach ($ vals as $ value) {$ type = $ value ['type']; $ tag = $ value ['tag']; $ level = $ value ['level']; $ attributes = isset ($ value ['bubuckets'])? $ Value ['bubuckets']: ""; $ val = isset ($ value ['value'])? $ Value ['value']: ""; switch ($ type) {case 'open': if ($ attributes! = "" | $ Val! = "") {$ Arr [$ t] ['tag'] = $ tag; $ arr [$ t] ['bubuckets'] = $ attributes; $ arr [$ t] ['level'] = $ level; $ t ++;} break; case "complete": if ($ attributes! = "" | $ Val! = "") {$ Arr [$ t] ['tag'] = $ tag; $ arr [$ t] ['bubuckets'] = $ attributes; $ arr [$ t] ['val'] = $ val; $ arr [$ t] ['level'] = $ level; $ t ++;} break ;}} echo "<pre>"; print_r ($ arr); echo "</pre>";?>

3. Use the SAX Parser to read the XML-----XML Simple API (SAX) parser

<?php $file="books.xml"; $xml = simplexml_load_file($file); echo "<pre>"; print_r($xml); echo "</pre>";?>
