This class represent the whole XML document as recursive hierarchic structure - each XmlNode can contain any number of child XmlNodes. XmlNode is mutable and U++ provides function to parse XML and store it to XmlNode and also to take XmlNode and create corresponding XML document.

static const XmlNode& Void()

Returns a constant reference to XmlNode representing "nothing". This reference is used as return value in cases where there are missing requested elements.

Returns true if XmlNode is Void.

Returns the type of node. Possible types are: XML_PI, XML_DECL, XML_COMMENT, XML_DOC, XML_TEXT, XML_TAG.

String GetText() const

String GetTag() const

Returns the text associated with node. If the node is XML_TAG, the text is tag-id. If the node is XML_TEXT, the text is ... the text. In other cases, like XML_PI, the text is the copy of element content.

Returns true if node is XML_TAG.

Returns true if node is XML_TAG and is equal to tag.

Returns true if node is

Clears all content.

Sets this XmlNode to represent XML tag with id tag.

void CreateText(const String& txt)

Sets this XmlNode to represent text with content txt.

void CreatePI(const String& pi)

Sets this XmlNode to represent processing info pi.

void CreateDecl(const String& decl)

Sets this XmlNode to represent XML declaration decl.

void CreateComment(const String& comment)

Sets this XmlNode to represent XML comment.

Set this XmlNode to be the top-level document node.

Returns true if this XmlNode represents XML_DOC and contains no content.

Same as !IsEmpty().

Returns a number of contained XmlNode sub-nodes.

XmlNode& At(int i)

Returns sub-node at index i. If there is no such node (number of sub-nodes is less than i + 1), number of nodes is extended to i + 1 with empty nodes.

const XmlNode& Node(int i) const

Returns node at index i. If there is none, behavior is undefined. This function is possibly slightly faster than either At or operator[].

const XmlNode& operator[](int i) const

Returns  i.

const XmlNode& operator[](const char *tag) const

Finds a XML_TAG sub-node with id tag and returns it. If no such node is found, returns Void().

XmlNode& Add()

Adds a new sub-node.

void AddText(const String& txt)

Adds a new text sub-node (XML_TEXT) and assigns it a text txt.

Finds a XML_TAG sub-node with id tag and returns its index. If no such sub-node exists, returns negative number.

XmlNode& Add(const char *tag)

Adds a new XML_TAG node with id tag and returns a reference to it.

XmlNode& GetAdd(const char *tag)

XmlNode& operator()(const char *tag)

Returns a reference to XML_TAG subnode with id tag. If no such node exists, adds it.

Removes XML_TAG sub-node with tag id. If there is no such sub-node, nothing happens.

String GatherText() const

String operator~() const

Concatenates all XML_TEXT sub-nodes in order of increasing indicies.

Returns the number of attributes of current node (it has to be XML_TAG to have any attributes - nonzero returned).

String AttrId(int i) const

Returns id of attribute i.

String Attr(int i) const

Returns the value of attribute i.

String Attr(const char *id) const

Returns the value of attribute id. If no such attribute exists, returns empty String.

XmlNode& SetAttr(const char *id, const String& val)

Sets the attribute id to have value val. Attribute does not have exist yet.

Returns the value of attribute id converted to integer. If no such attribute exists, returns def.

XmlNode& SetAttr(const char *id, int val)

Sets the attribute id to have integer value val.

void SetAttrsPick(pick_ VectorMap<String, String>& a)

Replaces all attributes to a using pick operation (a is destroyed in operation).

XmlNode()

Construct an empty XmlNode.

XmlNode ParseXML(XmlParser& p, dword style = XML_IGNORE_DECLS|XML_IGNORE_PIS|XML_IGNORE_COMMENTS)

XmlNode ParseXML(const char *s, dword style = XML_IGNORE_DECLS|XML_IGNORE_PIS|XML_IGNORE_COMMENTS)

Creates XmlNode parsing XML document supplied either as string or XmlParser. style can be a combination of

String AsXML(const XmlNode& n, dword style = XML_HEADER|XML_DOCTYPE)

Creates a XML document from XmlNode n. style can be a combination
