Summary of methods for PHP output of XML format data, php output of xml format

This example describes how PHP outputs XML format data. We will share this with you for your reference. The details are as follows:

Method 1:

<? Phpheader ("Content-type: text/xml"); echo "<? Xml version = '1. 0' encoding = 'utf-8'?> "; Echo" <users> "; echo" <user> "; echo" <name> "; echo" "; echo" </name> "; echo "<age>"; echo "24"; echo "</age>"; echo "<sex>"; echo "male"; echo "</sex> "; echo "</user>"; echo "<user>"; echo "<name>"; echo ""; echo "</name> "; echo "<age>"; echo "23"; echo "</age>"; echo "<sex>"; echo "female"; echo "</sex> "; echo "</user>"; echo "</users>";?>

The preceding example is run as follows:

Method 2:

<? Phpheader ("Content-type: text/xml"); echo "<? Xml version = '1. 0' encoding = 'utf-8'?> "; Echo "<users> <user> <name> ainiao </name> <age> 24 </age> <sex> male </sex> </user> <user> <name> Yan </name> <age> 23 </age> <sex> female </sex> </user> </users> ";?>

Method 3:

<? Phpheader ('content-Type: text/xml; '); // Create a new xml file $ dom = new DOMDocument ('1. 0 ', 'utf-8'); // create the <response> element $ response = $ dom-> createElement ('response '); $ dom-> a ($ response ); // create the <books> element and use it as the <response> sub-element $ books = $ dom-> createElement ('books '); $ response-> a ($ books); // create a title for the book $ title = $ dom-> createElement ('title '); $ titleText = $ dom-> createTextNode ('php and AJAX '); $ title-> a ($ titleText); // create an isbn element for the book $ isbn = $ dom -> CreateElement ('isbn '); $ isbnText = $ dom-> createTextNode ('1-21258986'); $ isbn-> a ($ isbnText ); // create the book element $ book = $ dom-> createElement ('book'); $ book-> a ($ title); $ book-> a ($ isbn ); // use <book> as the <books> sub-element $ books-> a ($ book ); // create an XML structure in a string variable $ xmlString = $ dom-> saveXML (); // output the XML string echo $ xmlString;?>

1. php output xml instance

header('Content-Type: text/xml');$sql = "select * from article order by post_date limit 100";$re = $db->query($sql);echo "<?xml version="1.0" encoding="utf-8"?>\n";echo "<data>\n";while($row = $db->fetchArray($re)){echo "<event ";echo "start="".strftime ("%b %d %Y %H:%M:%S", $row['post_date'])."" ";echo "title="".htmlspecialchars($row['title'])."" ";echo "link="tdetail.php?id=".$row['time_point'].""";echo ">";echo htmlspecialchars($row['content']);echo "</event>\n";}echo "</data>";

2. Use JavaScript to operate XML instances

Try to use all the operations and attributes for demonstration.

<Script language = "JavaScript"> <! -- Var doc = new ActiveXObject ("Msxml2.DOMDocument"); // ie5.5 +, CreateObject ("Microsoft. XMLDOM ") // load the document // doc. load ("B. xml "); // create a file header var p = doc. createProcessingInstruction ("xml", "version = '1. 0 'encoding= 'gb2312' "); // Add a file header doc. a (p); // obtain the root contact when loading directly. // var root = doc.doc umentElement; // create the root contact in either of the following ways: // var root = doc. createElement ("students"); var root = doc. createNode (1, "students", ""); // create a subpoint var n = doc. createNode (1, "ttyp", ""); // specifies the Child Contact text // n. text = "this is a test"; // create a sun contact var o = doc. createElement ("sex"); o. text = "male"; // specify its text // create the property var r = doc. createAttribute ("id"); r. value = "test"; // Add attribute n. setAttributeNode (r); // create the second property var r1 = doc. createAttribute ("class"); r1.value = "tt"; // Add attribute n. setAttributeNode (r1); // Delete the second attribute n. removeAttribute ("class"); // Add the sun Contact n. a (o); // Add text contacts n. a (doc. createTextNode ("this is a text node. "); // Add annotation n. a (doc. createComment ("this is a comment \ n"); // Add the Child Contact root. a (n); // copy the contact var m = n. cloneNode (true); root. a (m); // Delete the contact root. removeChild (root. childNodes (0); // create a data segment var c = doc. createCDATASection ("this is a cdata"); c. text = "hi, cdata"; // Add the data segment root. a (c); // Add the root contact doc. a (root); // find the contact var a = doc. getElementsByTagName_r ("ttyp"); // var a = doc. selectNodes ("// ttyp"); // display the attributes of the change contact for (var I = 0; I <. length; I ++) {alert (. xml); for (var j = 0; j <. attributes. length; j ++) {alert (. attributes [j]. name) ;}} // modify the node and use XPATH to locate the node var B = doc. selectSingleNode ("// ttyp/sex"); B. text = ""; // alert (doc. xml); // Save the XML file (you must use FSO on the server side and the client side) // doc. save (); // view the root contact XMLif (n) {alert (n. ownerDocument. xml);} // --> </script>
