The Node Method appendchild (newchild) is added to the end of all the child nodes. Return the added node clonenode (Boolean deep) to copy the current node. The copied node does not have a parent node, return to the copied node haschildnodes without parameters. Check whether the child node createelement creates an element node insertbefore (newchild, refchild) and inserts the node newchild before the child node refchild of the current node. Return the inserted node removechild (oldchild) to delete the child node oldchild and return the oldchild node. ReplaceChild (newchild, oldchild) replaces the node and returns that the deleted node nodelist is dynamic. Changes to the document are directly reflected in the relevant nodelist object.

Attribute: lengthitem (0)-Item (nodelist. Length-1) namednodemap contains nodes unordered. Indicates the correspondence between a node and a unique name. Property length method: getnameditem (name) returns the node item with the given name (0 ...) removenameditem (name) deletes the node setnameditem (name) with the given name and adds the node with the given node name to the current node set. If the changed name already exists, ASP has many advantages over access in retrieving and updating small data volumes by using xmldom to operate XML files on the server. I have tested whether to use a database and store all the Website member information, product data information, transaction information, and website customization information in three XML files. The running result is normal, it seems that it is much faster than the database, but it is not tested and cannot be determined.
