This is part of the xml file. it is to extract the values following the value tag one by one from it. it is better to know several records.
It can be applied to a defined function, such
Function value ($ a, $ B, $ c, $ d, $ n ){
.......
}
For (I = 1; I <(number of records); I ++ ){
Value ($ a, $ B, $ c, $ d, $ I );
}
Cycles:
First implementation of value (13.82, 13.94, 13.79, 13.85, 1)
Second implementation value (13.82, 13.86, 13.58, 13.60, 2)

A regular expression is not required. you can use the function to obtain xml data .. Thank you!

Php provides a dedicated method

$s =<<< XML
