PHP learning-XML

[Create XML]

$ Dom = new domdocument ("1.0 ");
$ Book = $ dom-> appendchild ($ dom-> createelement ('book'); // create a root element
$ Title = $ book-> appendchild ($ dom-> createelement ('title'); // create a node under the root element
$ Title-> appendchild ($ dom-> createtextnode ('php cookbook'); // create a subnode under the node
$ Title-> setattribute ("cover", "soft"); // create an attribute under the title Node

$ Sklar = $ book-> appendchild ($ dom-> createelement ('author '));
// $ Sklar-> appendchild ($ dom-> createtextnode ('sklar '));

$ Name = $ Sklar-> appendchild ($ dom-> createelement ('name '));
$ Name-> appendchild ($ dom-> createtextnode ('fsl '));

$ TRAC = $ book-> appendchild ($ dom-> createelement ('author '));

$ Dom-> formatoutput = true;
Echo $ dom-> savexml ();

[XML file processing method-XPath]

$ S = simplexml_load_file ("12-1.xml ");

Foreach ($ pname as $ name)

Foreach ($ per as $ person ){
List ($ age) = $ person-> XPath ("Age ");
List ($ city) = $ person-> XPath ("Address/City ");
List ($ Pro) = $ person-> XPath ("Address/province"); // process nodes with subnodes

Echo $ city. "_". $ pro. ":". $ age. "<br> ";
}

 

$ Dom = new domdocument;
$ Dom-> load ("12-1.xml ");
$ XPath = new domxpath ($ DOM );
$ Did = $ XPath-> query ("/people/person/@ ID ");

Foreach ($ did as $ id)

[Apply XSLT]

PHP extension php_xsl must be enabled

$ XSL = new domdocument;
$ XSL-> load ('7-2. XSL ');

$ XSLT = new xsltprocessor ();

$ Xml = new domdocument;
$ XML-> load ('12-1. xml'); // double Parameter Problem

$ Results = $ XSLT-> transformtoxml ($ XML );

$ Results2 = $ XSLT-> transformtouri('results.html ');

$ Results3 = $ XSLT-> transformtodoc ($ XML );
