Hello experts

I am new to XML but i am doing efforts to learn it.

Here is my problem:



I have created an XML using simpleXML. Now I need to parse it somehow and replace the values of some nodes.



I made a html form that creates me the XML, but in this way I need to fill in ALL values for ALL nodes which i don't want.



I only want to be able to modify just ONE (or two .. ) elements.



With my form, if I only fill the attributes for one element, i get a XML file with one element that contain values and 4 empty attribute element nodes.



Here is the xml file i created:

and here is the form that creates it:

Can somebody help ???



I would like to be able to modify one element and the rest to remain unchanged. As far as i know it can be done using DOM.



Any help is highly appreciated.



Thank you in advance,

Adrian
