ooops, when i find an element node and want to set a new value for it, i
have to
seek for the appropriate child node with name "#text" and set the value for
this
child node. please try to call this function when you have found a node by
name:
/**
* Sets a tag's value by given node.
*
* @param n the node of the tag
* @param value_new the new value for the tag
* @return value_old the old value of the tag in a string
*
*/
private String SetValueByNode(Node n, String value_new)
{
String value_old = "";
if (null != n)
{
NodeList nl = n.getChildNodes();
Node cn = null;
int type = -1;
int len = nl.getLength();
for ( int i = 0; i < len; i++ )
{
cn = nl.item(i);
type = cn.getNodeType();
if ( type == Node.TEXT_NODE )
{
value_old = cn.getNodeValue();
cn.setNodeValue(value_new);
break;
}
}
}
return value_old;
}
cheers,
Peter
