[xml] Basic newbie Q about parsing trees

[Yan Seiner]

I have a simple XML data tree that looks like this:

<?xml version="1.0" ?>
<pivot>
    <field>
        <line_0>
                <currentField>103</currentField>
        </line_0>
        <line_1>
                <bearingFrom>0.000</bearingFrom>
                <bearingTo>0.000</bearingTo>
                <auxA>0</auxA>
                <auxB>2</auxB>
                <auxC>4</auxC>
                <auxD>6</auxD>
        </line_1>
        <line_2>
                <bearingFrom>0.000</bearingFrom>
                <bearingTo>0.000</bearingTo>
                <auxA>0</auxA>
                <auxB>0</auxB>
                <auxC>0</auxC>
                <auxD>0</auxD>
        </line_2>
   </field>
</pivot>

The line_X elements can repeat a number of times.

I need to parse this data out to a C array.  I've used the tree1.c 
example to walk the tree and print element names, but how do I print the 
element values?

Basically, I need to a) fill a C array with values in the tree, and b) 
fill a tree with values from a C array, as simply as possible.  I've 
been through the examples, but this is the first time I've worked with 
libxml2 and the API is a bit cryptic at the moment.

Thanks,
