A function called to acquire namespaces (xmlNs) from the wrapper.

`ctxt`: | a DOM wrapper context
`node`: | the context node (element or attribute)
`nsName`: | the requested namespace name
`nsPrefix`: | the requested namespace prefix
`Returns`: | an xmlNsPtr or NULL in case of an error.

### xmlAddChild ()

    xmlNodePtr	xmlAddChild		(xmlNodePtr parent,
    					 xmlNodePtr cur)

Add a new node to @parent, at the end of the child (or property) list merging adjacent TEXT nodes (in which case @cur is freed) If the new node is ATTRIBUTE, it is added into properties instead of children. If there is an attribute with equal name, it is first destroyed.

`parent`: | the parent node
`cur`: | the child node
`Returns`: | the child or NULL in case of error.

### xmlAddChildList ()

    xmlNodePtr	xmlAddChildList		(xmlNodePtr parent,
    					 xmlNodePtr cur)

Add a list of node at the end of the child list of the parent merging adjacent TEXT nodes (@cur may be freed)

`parent`: | the parent node
`cur`: | the first node in the list
`Returns`: | the last child or NULL in case of error.

### xmlAddNextSibling ()

    xmlNodePtr	xmlAddNextSibling	(xmlNodePtr cur,
    					 xmlNodePtr elem)

Add a new node @elem as the next sibling of @cur If the new node was already inserted in a document it is first unlinked from its existing context. As a result of text merging @elem may be freed. If the new node is ATTRIBUTE, it is added into properties instead of children. If there is an attribute with equal name, it is first destroyed.

`cur`: | the child node
`elem`: | the new node
`Returns`: | the new node or NULL in case of error.

### xmlAddPrevSibling ()

    xmlNodePtr	xmlAddPrevSibling	(xmlNodePtr cur,
    					 xmlNodePtr elem)

Add a new node @elem as the previous sibling of @cur merging adjacent TEXT nodes (@elem may be freed) If the new node was already inserted in a document it is first unlinked from its existing context. If the new node is ATTRIBUTE, it is added into properties instead of children. If there is an attribute with equal name, it is first destroyed.

`cur`: | the child node
`elem`: | the new node
`Returns`: | the new node or NULL in case of error.

### xmlAddSibling ()

    xmlNodePtr	xmlAddSibling		(xmlNodePtr cur,
    					 xmlNodePtr elem)

Add a new element @elem to the list of siblings of @cur merging adjacent TEXT nodes (@elem may be freed) If the new element was already inserted in a document it is first unlinked from its existing context.

`cur`: | the child node
`elem`: | the new node
`Returns`: | the new element or NULL in case of error.
