How manipulate xml in php?
Show There are no user contributed notes for this page. Many examples in this reference require an XML string. Instead of repeating this string in every example, we put it into a file which we include in each example. This included file is shown in the following example section. Alternatively, you could create an XML document and read it with simplexml_load_file(). Example #1 Include file example.php with XML string

Example #3 Getting
$movies->movie->{'great-lines'}->line; The above example will output: PHP solves all my web problems Example #4 Accessing non-unique elements in SimpleXML When multiple instances of an element exist as children of a single parent element, normal iteration techniques apply.

$movies->xpath('//character') as $character) { ' The above example will output: Ms. Coder played by Onlivia Actora Mr. Coder played by El ActÓr Example #9 Setting values Data in SimpleXML doesn't have to be constant. The object allows for manipulation of all of its elements.
