|
Returns : |
gboolean cong_document_for_each_node (CongDocument *doc, CongDocumentRecursionCallback callback, gpointer callback_data);
Perform a depth-first traversal of the nodes in the DOM tree of this document, calling the supplied callback for each node, passing it the supplied data.
If the callback returns TRUE, then traversal is halted: you can use this to test for the presence of a node satisfying some condition Otherwise, traversal continues. If you wish to perform some operation on every node in the tree, your callback should always return FALSE.
Entity declarations are only visited once; it does not traverse below an entity reference, to avoid potential infinite loops.
|
the document |
|
a callback to be invoked for every node in the document |
|
data for the callback |
Returns : |
TRUE if one of the callback calls returned TRUE (stopping the traversal prematurely); FALSE if the full traversal occurred |
gboolean cong_document_for_each_child_of_node (CongDocument *doc, CongNodePtr parent, CongDocumentRecursionCallback callback, gpointer callback_data);
Visit each of the direct descendents of the given node, calling the supplied callback for each, passing it the supplied data.
If the callback returns TRUE, then traversal is halted: you can use this to test for the presence of a node satisfying some condition Otherwise, traversal continues. If you wish to perform some operation on every child node, your callback should always return FALSE.
|
the document |
|
a node in the document |

a pointer to the <placeholder> element (with a miniature DOM tree below it corresponding to the XML source), or NULL if a parse error occurred. The "document" of these nodes is set up correctly, but they are not linked into the DOM tree. |
xmlElementPtr cong_document_get_dtd_element (CongDocument *cong_doc, CongNodePtr node);
Helper function to get the xmlElementPtr within the DTD for a node Currently only looks at the actual DTD, but in future might attempt to use the dispspec to infer an DTD and return that So don't store the return value; it might get deleted etc
|
|
|
|
Returns : |
GList * cong_document_get_valid_new_child_elements (CongDocument *doc, CongNodePtr node, CongElementType tag_type);

gboolean cong_document_node_can_be_deleted (CongDocument *doc, CongNodePtr node);
Helper function that determines if a node can safely be deleted. It will fail if the node or its subtree contains the cursor or the start/end of the selection, to avoid these containing dangling pointers to dead memory. Used to fix bug 108530, to ensure that the cursor and selection are always moved out of the way.
