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
