    I have a really stupid problem I have not been able to solve (Firefox2) :
    :confused:

    I have an xhtml page that must load an xml file with JavaScript, extract same values and print them.
    Everything goes in the right way, until I make the xhtml page print a value twice:

    HTML:
    <body onload="LoadXMLdata()">
       value = <span id="value" />            <!-- ok -->
       value = <span id="value" />            <!-- here no value is printed! -->
    </body>
    
    It must not be possible that when a variable is printed, it is automatically reset!

    :(

    Please put up the JavaScript code, otherwise it's not possible to isolate the bug.

    Here it is.

    This is the output I to get on the browser (Firefox2):

    time = 0.05
    time =

    This is the output I would like to get:

    time = 0.05
    time = 0.05

    Thank you for any information.
    OutputData.xml
    Code:
    <params>
    	<time>0.05</time>
    	<iterations>28</iterations>
    	<error>1.26</error>
    </params>
    
    printTwice.xhtml
    Code:
    <?xml version="1.0" encoding="UTF-8"?>
    
    <!-- printTwice.xhtml
    	 Find out why when I print the same variable more than once, this is effectively printed the first time only.

    > You cannot have 1 or more elements with the same id

    All I have to do is to print a value (obtained from a file) twice on the same web page.
    It *must* be possible somehow...
