This article mainly introduces the php xml Parsing method, and analyzes in detail the related skills of php XML parsing in the form of examples, for more information about how to parse xml in php, see the following example. Share it with you for your reference. The specific analysis is as follows:

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-> getElementsByTagName ("price")-> item (0)-> nodeValue; echo "title :". $ title."
"; Echo" author: ". $ author ."
"; Echo" year: ". $ year ."
"; Echo" price: ". $ price ."
"; Echo "***********************************
";}?>
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""; print_r($arr); echo "
";?>
3. use the SAX parser to read the XML-----XML Simple API (SAX) parser
<?php $file="books.xml"; $xml = simplexml_load_file($file); echo ""; print_r($xml); echo "
";?>
