Php method for creating XML documents based on DOM

This article mainly introduces the PHP method of creating XML documents based on DOM, and analyzes the related operation skills of PHP using DOM to create XML format files, which can be referenced by friends.

The example in this article describes how PHP creates XML documents based on the DOM. Share to everyone for your reference, as follows:

DOM Create XML document

Create the following document with the DOM:

<booklist> <book id= "1" > <title> tianlong eight </title> <author> Jin Yong </author> <content > <! [Cdata[Tianlong Eight is a novel written by Jin Yong, very good-looking! ]]> </content> </book></booklist>

Implementation steps:

1, create the DOM object--"2, create a node--" 3, create a subordinate node--"4, add the subordinate node to the ancestor node--" 5, create the attribute node--"6, add the attribute node to the node that owns the attribute--" 7, if there is a node repeat 2~6 step--"8, Add the highest node (that is, the root node) to the DOM object--"9, open or store the XML document.

The process of creating a node can either be created from the most subordinate node or start from the root node. The implementation code is as follows:

<?phpheader (' content-type:text/xml; '); $dom = new DOMDocument (' 1.0 ', ' utf-8 ');//Build DOM Object $no1 = $dom->createelement (' Booklist ');//Create normal node:booklist$dom-> AppendChild ($no 1);//Add the Booklist node to the DOM document $NO2 = $dom->createelement (' book ');//Create Book node $no1->appendchild ($ NO2);//Add the book node to the Booklist node $no3 = $dom->createattribute (' id ');//Create attribute node: Id$no3->value = 1;//Assign value to attribute node $no2-> AppendChild ($no 3);//Add the attribute node to the book node $no3 = $dom->createelement (' title '), $no 2->appendchild ($no 3); $no 4 = $dom- >createtextnode (' Tianlong Eight ');//Create Text node: Tianlong eight $no3->appendchild ($no 4);//Add Tianlong eight nodes to the book node $NO3 = $dom createelement (' author '); $no 2->appendchild ($no 3); $no 4 = $dom->createtextnode (' Jin Yong ');//Create Text node: Tianlong eight $no3-> AppendChild ($no 4);//Add the Tianlong eight node to the book node $no3 = $dom->createelement (' content '); $no 2->appendchild ($no 3); $no 4 = $ Dom->createcdatasection (' Tian Long Eight is a martial arts fiction written by Jin Yong, very good-looking! ');//Create the text CDATA node $no3->appendchild ($no 4);//Add the Tianlong eight nodes to the book Node header (' Content-type:text/html;charset=utf-8 '); echo $dom->save (' bookList.xml ')? ' Storage succeeded ': ' Storage failed ';//stored as XML document/* Directly open header (' Content-type:text/xml ') in XML document format; echo $dom->savexml ();*/?>
