   Tianlong BabuJin Yong　　　　
   
    　　　　　　 天龙八部是金庸写的一本武侠小说，非常好看！ 　　　　
   　　
  
 

Steps:

1. create a DOM object. 2. create a node. 3. create a lower-level node. 4. add a lower-level node to a higher-level node. 5. create an attribute node. 6. add an attribute node to a node that owns this attribute ~ Step 6 -- "8. add the highest level node (namely the root node) to the DOM object. --" 9. open or store the xml document.

You can create a node from either the lower-level node or the root node. The implementation code is as follows:

 CreateElement ('booklist'); // create a common node: booklist $ dom-> appendChild ($ no1 ); // add the booklist node to the DOM document $ no2 = $ dom-> createElement ('book'); // Create a book node $ no1-> appendChild ($ no2 ); // add the book node to the booklist node $ no3 = $ dom-> createAttribute ('id'); // Create an attribute node: id $ no3-> value = 1; // assign $ no2-> appendChild ($ no3) to the attribute node; // add the attribute node to the book node $ no3 = $ dom-> createElement ('title '); $ no2-> appendChild ($ no3); $ no4 = $ dom-> createTextNode ('tianlong Babu '); // create a text node: Tianlong 8 Department $ no3-> appendChild ($ no4); // add the Tianlong Babu node to the book node $ no3 = $ dom-> createElement ('author '); $ no2-> appendChild ($ no3); $ no4 = $ dom-> createTextNode ('jinyong '); // create a text node: tianlong Babu $ no3-> appendChild ($ no4); // add the Tianlong Babu node to the book node $ no3 = $ dom-> createElement ('content '); $ no2-> appendChild ($ no3); $ no4 = $ dom-> createCDATASection ('tianlong Babu is a martial arts novel written by Jin Yong. it looks great! '); // Create the file CDATA node $ no3-> appendChild ($ no4); // add the Tianlong Babu node to the header ('content-type: text/html; charset = utf-8 '); echo $ dom-> save ('booklist. XML ')? 'Storage successfully': 'Storage failed'; // The storage is an xml document/* open the header directly in xml document format ('content-type: text/XML '); echo $ dom-> savexml (); */?>
