* Get domxml support function with Get_defined_functions ()
*
* Currently Domxml does not support non-iso-8859-1 language declarations
* Support
* Not supported
* So it needs to be transformed into this, which may require
* Utf8_encode () Utf8_decode () function for processing

* Function List
* String domxml_version (void) Returns the version number of the Domxml
* Object XmlDoc (String str) DOMDocument object that creates XML from a string
* Object Xmldocfile (string filename) DOMDocument object that creates XML from a file
* Object Xmltree (String str) parses the XML document, returns the tree structure, cannot be changed with the Domxml function
* Resource Domxml_add_root (Resource doc,string name) add root node
* String Domxml_dumpmem (Resource doc) converts the Domxml object into an XML string. This function has a problem, he will precede the first character with an extended ASCII character, such as & #nnn;
* Domxml_node_attributes
* Domxml_elem_get_attribute
* Domxml_elem_set_attribute
* Array Domxml_node_children (object doc|node) returns child nodes
* Domxml_node_new_child

Document XML source tree. XML content
$testxml = '
When reading an XML document, the processor forms a tree, which we call the source tree.
The tree has various types of nodes in the table.
Source tree node
| Node type |
description |
| Root (Root) |
This is the root node of the tree. can appear anywhere in the tree. The root node has only one child node, which refers to the document element node in the XML document. |
| Element (element) |
This node is used for any element in the document. The child nodes of an element node can be element nodes of their content, annotation nodes, processing information nodes, and text nodes. All the text that appears in the |
| text (text) |
document is grouped into a text node. A text node may not have a front or rear sibling node that is immediately followed by a text node. |
| Attribute (properties) |
Each element node has its own attached attribute node. The default property value is handled in the same way as the specified property. None of these nodes have child nodes. |
| Namespace (name) |
There is a name space node for each element that begins with Xlmns: and the attribute node. These nodes do not have child nodes. |
| processing instruction (processing instructions) |
Each processing instruction has a separate node. None of these nodes have child nodes. |
| Comment (note) |
each has a comment node. None of these nodes have child nodes. |
