This is useful on Windows systems. -* Additional support for text and CDATA sections. - * The `Element.Text` method now returns the concatenation of all consecutive - character data tokens immediately following an element's opening tag. - * Added `Element.SetCData` to replace the character data immediately - following an element's opening tag with a CDATA section. - * Added `Element.CreateCData` to create and add a CDATA section child - `CharData` token to an element. - * Added `Element.CreateText` to create and add a child text `CharData` token - to an element. - * Added `NewCData` to create a parentless CDATA section `CharData` token. - * Added `NewText` to create a parentless text `CharData` - token. - * Added `CharData.IsCData` to detect if the token contains a CDATA section. - * Added `CharData.IsWhitespace` to detect if the token contains whitespace - inserted by one of the document Indent functions. - * Modified `Element.SetText` so that it replaces a run of consecutive - character data tokens following the element's opening tag (instead of just - the first one). -* New "tail text" support. - * Added the `Element.Tail` method, which returns the text immediately - following an element's closing tag. - * Added the `Element.SetTail` method, which modifies the text immediately - following an element's closing tag. -* New element child insertion and removal methods. - * Added the `Element.InsertChildAt` method, which inserts a new child token - before the specified child token index. - * Added the `Element.RemoveChildAt` method, which removes the child token at - the specified child token index. -* New element and attribute queries. - * Added the `Element.Index` method, which returns the element's index within - its parent element's child token list. - * Added the `Element.NamespaceURI` method to return the namespace URI - associated with an element. - * Added the `Attr.NamespaceURI` method to return the namespace URI - associated with an element. - * Added the `Attr.Element` method to return the element that an attribute - belongs to. -* New Path filter functions. - * Added `[local-name()='val']` to keep elements whose unprefixed tag matches - the desired value. - * Added `[name()='val']` to keep elements whose full tag matches the desired - value. - * Added `[namespace-prefix()='val']` to keep elements whose namespace prefix - matches the desired value. - * Added `[namespace-uri()='val']` to keep elements whose namespace URI - matches the desired value. - -**Bug Fixes** - -* A default XML `CharSetReader` is now used to prevent failed parsing of XML - documents using certain encodings. - ([Issue](https://github.com/beevik/etree/issues/53)). -* All characters are now properly escaped according to XML parsing rules. - ([Issue](https://github.com/beevik/etree/issues/55)). -* The `Document.Indent` and `Document.IndentTabs` functions no longer insert - empty string `CharData` tokens. - -**Deprecated** - -* `Element` - * The `InsertChild` method is deprecated.
