The Document
Object Model (DOM) and the SAX Parser are commonly used for parsing
an xml document using PHP. Most of the developers would have use the
DOM is other languages too for parsing an xml document.
_______________________________________________
It is an
easy way to do and there is a limitation in it. If the xml file is large
it is difficult to handle it using DOM. In the case of a SAX parser
you can handle large files easily.
With the
DOM you have to create a new document object and then load the xml file
needed in it. Then using the functions available to navigate through
the xml document, you can navigate and get the values of the nodes and
print it out. In PHP you can use, new DOMDocument(), load('xmlfile.xml'),
getElementsByTagName(), and item(n)->nodeValue to work with the xml
document.
When you
use the getElementsByTagName function, all the elements in that name
will be loaded in an array. Then you have to loop through the array
to get the values of individual elements through item(n)->nodeValue.
