This exception class is thrown by xmlwrapp for all runtime XML-related errors along with the xml::par...

The xml::node class is used to hold information about one XML node.

iterator parent(void)

Get an iterator that points at the parent of this node.

The xml::ns class is used to access and handle namespaces of nodes and attributes.

static DLIST_TYPE *DLIST_NAME() prev(DLIST_LIST_TYPE *list, DLIST_TYPE *item)

This file contains the definition of the xml::exception class.

xmlNodePtr node_replace(xmlNodePtr old_node, xmlNodePtr new_node)

Replace a node with another one.

void erase_ns_definition(xmlNodePtr node, xmlNsPtr definition)

Erases namespace definition in the node.

xmlNsPtr lookup_default_ns_above(xmlNodePtr node)

Searches for a default namspace definition in the given node and above.

xmlNodePtr node_erase(xmlNodePtr to_erase)

Erase a node from the child list, and then free it from memory.

void set_children_default_ns(xmlNodePtr node, xmlNsPtr default_ns)

Set the node and its children default namespace to the given.

void update_children_default_ns(xmlNodePtr node, xmlNsPtr newns)

Replaces the node and its children default namespace with the given.

bool is_ns_used(xmlNodePtr node, xmlNsPtr ns)

Check if the node, attributes and children use the namespace.

void replace_ns(xmlNodePtr node, xmlNsPtr oldNs, xmlNsPtr newNs)

Replaces old namspace with a new one in nodes and attributes all the way down in the hierarchy.

bool has_default_ns_definition(xmlNodePtr node)

Check if the node holds default namespace definition.

xmlNodePtr node_insert(xmlNodePtr parent, xmlNodePtr before, xmlNodePtr to_add)

Insert a node somewhere in the child list of a parent node.

xmlNsPtr lookup_ns_definition(xmlNodePtr node, const char *prefix)

Searches for a namspace definition in the given node.

This file contains the definition of the xml::node manipulation functions.
