Creating an XML document from scratch
You can create an XML document in a script using the appropriate PBDOM_OBJECT
subclasses and methods. The following code uses the PBDOM_ELEMENT
and PBDOM_DOCUMENT classes and some of their methods to
create a simple XML document.
First, the objects are declared and instantiated:
|
1 |
PBDOM_ELEMENT pbdom_elem_1<br>PBDOM_ELEMENT pbdom_elem_2<br>PBDOM_ELEMENT pbdom_elem_3<br>PBDOM_ELEMENT pbdom_elem_root<br>PBDOM_DOCUMENT pbdom_doc1<br> <br>pbdom_elem_1 = Create PBDOM_ELEMENT<br>pbdom_elem_2 = Create PBDOM_ELEMENT<br>pbdom_elem_3 = Create PBDOM_ELEMENT |
The instantiated objects are assigned names. Note that the PBDOM_DOCUMENT
object pbdom_doc1 is not named:
|
1 |
pbdom_elem_1.SetName("pbdom_elem_1")<br>pbdom_elem_2.SetName("pbdom_elem_2")<br>pbdom_elem_3.SetName("pbdom_elem_3") |
The objects are arranged into a node tree using the AddContent method.
The AddContent method adds the referenced object
as a child node under the object from which AddContent is
invoked:
|
1 |
pbdom_elem_1.AddContent(pbdom_elem_2)<br>pbdom_elem_2.AddContent(pbdom_elem_3) |
Use the NewDocument method to create a
new XML document. The parameter value supplied to the NewDocument method
becomes the name of the root element. This name is then accessed
from the PBDOM_DOCUMENT object pbdom_doc1 and
assigned to the PBDOM_ELEMENT object pbdom_elem_root using
the GetRootElement method:
|
1 |
pbdom_doc1.NewDocument("Root_Element_From_Doc_1")<br>pbdom_elem_root = pbdom_doc1.GetRootElement() |
The ELEMENT object pbdom_elem_1 and
all its child nodes are placed in the new XML document node tree
under the root element using the AddContent method.
Note that as the ancestor node pbdom_elem_1 is
placed in the node tree, all its child nodes move as well:
|
1 |
pbdom_elem_root.AddContent(pbdom_elem_1) |
The XML document created looks like this:
|
1 |
<!DOCTYPE Root_Element_From_Doc_1> <br><Root_Element_From_Doc_1><br>    <pbdom_elem_1><br>        <pbdom_elem_2><br>            <pbdom_elem_3/> <br>        </pbdom_elem_2><br>    </pbdom_elem_1><br></Root_Element_From_Doc_1> |
