<H2><A NAME="4_4">Changing Node Values</A></H2>
|
|
<P>All of the examples so far have concentrated on creating and loading
|
|
new XML data nodes. Many applications, however, need to manipulate or
|
|
change the nodes during their operation, so Mini-XML provides functions
|
|
to change node values safely and without leaking memory.</P>
|
|
<P>Existing nodes can be changed using the <A href="mxmlSetElement.html#mxmlSetElement">
|
|
<TT>mxmlSetElement()</TT></A>, <A href="mxmlSetInteger.html#mxmlSetInteger">
|
|
<TT>mxmlSetInteger()</TT></A>, <A href="mxmlSetOpaque.html#mxmlSetOpaque">
|
|
<TT>mxmlSetOpaque()</TT></A>, <A href="mxmlSetReal.html#mxmlSetReal"><TT>
|
|
mxmlSetReal()</TT></A>, and <A href="mxmlSetText.html#mxmlSetText"><TT>
|
|
mxmlSetText()</TT></A> functions. For example, use the following
|
|
function call to change a text node to contain the text "new" with
|
|
leading whitespace:</P>
|
|
<PRE>
|
|
<A href="mxmlnodet.html#mxml_node_t">mxml_node_t</A> *node;
|
|
|
|
<A href="mxmlSetText.html#mxmlSetText">mxmlSetText</A>(node, 1, "new");
