Preferences for any number of users can be held in a single xml file having elements for each user name with user specific preferences as attributes of child elements. The separate pref/ 's could of course be combined as multiple attributes of a single pref/ element but this could get unwieldy.

Otherwise, php treats the element as an object.". If a tag contains cdata, simplexml remembers that fact, by representing it separately from the string content of the element.

Php xml amp; xml entities /foo print_r(xml simplexmlelement essay Object ( 0 text1 xml entities ) xml2 raw data /foo print_r(xml2 simplexmlelement Object ( ) / Where's my cdata?

Reading from a string Hacking with php - practical php. While simplexml_load_file loads xml data from a file, simplexml_load_string loads xml data from a string. This is generally not as useful, but it does allow you to easily load several xml files into one string, then use that inside one simplexml structure. Take a look at the following script? Php employees eot employees employee id"2" foo"BAR" name Anthony Clarke /name title Chief Information Officer /title age 48 /age /employee employee id"2" baz"WOM" name laura pollard /name title Chief Executive officer /title age 54 /age /employee /employees eot; employees foreach (employees- employee as employee) print. As you can see, the majority of the script is just mini there heredoc-style string assignment that sets up the xml. Then, with a call to simplexml_load_string, the xml is parsed into the employees object, just as with the simplexml_load_file function. The resulting object is no different, as can be seen with the output from the foreach loop.
