\section{\class{wxXmlNode}}\label{wxxmlnode}

Represents a node in an XML document. See \helpref{wxXmlDocument}{wxxmldocument}.

Node has a name and may have content
and properties. Most common node types are {\tt wxXML\_TEXT\_NODE} (name and
properties are irrelevant) and {\tt wxXML\_ELEMENT\_NODE} (e.g. in {\tt <title>hi</title>} there is
an element with name="title", irrelevant content and one child ({\tt wxXML\_TEXT\_NODE}
with content="hi").

If wxUSE\_UNICODE is 0, all strings are encoded in the encoding given to Load
(default is UTF-8).

\membersection{wxXmlNode::wxXmlNode}\label{wxxmlnodewxxmlnode}


\func{}{wxXmlNode}{\param{wxXmlNode* }{parent}, \param{wxXmlNodeType }{type}, \param{const wxString\& }{name}, \param{const wxString\& }{content = wxEmptyString}, \param{wxXmlProperty* }{props = NULL}, \param{wxXmlNode* }{next = NULL}}

\wxheading{Parameters}

\docparam{parent}{The parent node. Can be NULL.}
\docparam{type}{One of the wxXmlNodeType enumeration value.}
\docparam{name}{The name of the node. This is the string which appears between angular brackets.}
\docparam{content}{The content of the node. Only meaningful when {\it type} is {\tt wxXML\_TEXT\_NODE} or {\tt wxXML\_CDATA\_SECTION\_NODE}.}
\docparam{props}{If not NULL, this wxXmlProperty object and its eventual siblings are attached to
the node.}
\docparam{next}{If not NULL, this node and its eventual siblings are attached to
the node.}

\func{}{wxXmlNode}{\param{const wxXmlNode\& }{node}}

Copy constructor. Note that this does NOT copy syblings
and parent pointer, i.e. \helpref{GetParent()}{wxxmlnodegetparent} and \helpref{GetNext()}{wxxmlnodegetnext} will return NULL
after using copy ctor and are never unmodified by operator=.

On the other hand, it DOES copy children and properties.


\func{}{wxXmlNode}{\param{wxXmlNodeType }{type}, \param{const wxString\& }{name}, \param{const wxString\& }{content = wxEmptyString}}

A simplified version of the first constructor form.


\membersection{wxXmlNode::\destruct{wxXmlNode}}\label{wxxmlnodedtor}

\func{}{\destruct{wxXmlNode}}{\void}

The virtual destructor. Deletes attached children and properties.

\membersection{wxXmlNode::AddChild}\label{wxxmlnodeaddchild}

\func{void}{AddChild}{\param{wxXmlNode* }{child}}

Adds the given node as child of this node. To attach a second children to this node, use the
\helpref{SetNext()}{wxxmlnodesetnext} function of the {\it child} node.

\membersection{wxXmlNode::AddProperty}\label{wxxmlnodeaddproperty}

\func{void}{AddProperty}{\param{const wxString\& }{name}, \param{const wxString\& }{value}}

Appends a property with given {\it name} and {\it value} to the list of properties for this node.

\func{void}{AddProperty}{\param{wxXmlProperty* }{prop}}

Appends the given property to the list of properties for this node.

\membersection{wxXmlNode::DeleteProperty}\label{wxxmlnodedeleteproperty}

\func{bool}{DeleteProperty}{\param{const wxString\& }{name}}

Removes the first properties which has the given {\it name} from the list of properties for this node.

\membersection{wxXmlNode::GetChildren}\label{wxxmlnodegetchildren}

\constfunc{wxXmlNode*}{GetChildren}{\void}

Returns the first child of this node.
To get a pointer to the second child of this node (if it does exist), use the
\helpref{GetNext()}{wxxmlnodegetnext} function on the returned value.

\membersection{wxXmlNode::GetContent}\label{wxxmlnodegetcontent}

\constfunc{wxString}{GetContent}{\void}

Returns the content of this node. Can be an empty string.

\membersection{wxXmlNode::GetName}\label{wxxmlnodegetname}

\constfunc{wxString}{GetName}{\void}

Returns the name of this node. Can be an empty string (e.g. for nodes of type {\tt wxXML\_TEXT\_NODE} or {\tt wxXML\_CDATA\_SECTION\_NODE}).

\membersection{wxXmlNode::GetNext}\label{wxxmlnodegetnext}

\constfunc{wxXmlNode*}{GetNext}{\void}

Returns a pointer to the sibling of this node or NULL if there are no siblings.

\membersection{wxXmlNode::GetParent}\label{wxxmlnodegetparent}

\constfunc{wxXmlNode*}{GetParent}{\void}

Returns a pointer to the parent of this node or NULL if this node has no parent.

\membersection{wxXmlNode::GetPropVal}\label{wxxmlnodegetpropval}

\constfunc{bool}{GetPropVal}{\param{const wxString\& }{propName}, \param{wxString* }{value}}

Returns \true if a property named {\it propName} could be found.
If the {\it value} pointer is not NULL, the value of that property is saved there.

\constfunc{wxString}{GetPropVal}{\param{const wxString\& }{propName}, \param{const wxString\& }{defaultVal}}

Returns the value of the property named {\it propName} if it does exist.
If it does not exist, the {\it defaultVal} is returned.

\membersection{wxXmlNode::GetProperties}\label{wxxmlnodegetproperties}

\constfunc{wxXmlProperty*}{GetProperties}{\void}

Return a pointer to the first property of this node.

\membersection{wxXmlNode::GetType}\label{wxxmlnodegettype}

\constfunc{wxXmlNodeType}{GetType}{\void}

Returns the type of this node.


\membersection{wxXmlNode::HasProp}\label{wxxmlnodehasprop}

\constfunc{bool}{HasProp}{\param{const wxString\& }{propName}}

Returns \true if this node has a property named {\it propName}.

\membersection{wxXmlNode::InsertChild}\label{wxxmlnodeinsertchild}

\func{void}{InsertChild}{\param{wxXmlNode* }{child}, \param{wxXmlNode* }{before\_node}}

Inserts the {\it child} node after {\it before\_node} in the children list.

\membersection{wxXmlNode::RemoveChild}\label{wxxmlnoderemovechild}

\func{bool}{RemoveChild}{\param{wxXmlNode* }{child}}

Removes the given node from the children list. Returns \true if the node was found and removed
or \false if the node could not be found.

\membersection{wxXmlNode::SetChildren}\label{wxxmlnodesetchildren}

\func{void}{SetChildren}{\param{wxXmlNode* }{child}}

Sets as first child the given node. The caller is responsible to delete any previously present
children node.

\func{void}{SetName}{\param{const wxString\& }{name}}

Sets the name of this node.

\membersection{wxXmlNode::SetNext}\label{wxxmlnodesetnext}

\func{void}{SetNext}{\param{wxXmlNode* }{next}}

sibling node.

\membersection{wxXmlNode::SetParent}\label{wxxmlnodesetparent}
