XMLSpear a powerful graphical tree editor, targeted to check, and correct XML files in a simple way.
You can assign a schema or DTD to validate the xml. For correcting not-wellformed xml a simple source editor is available.

Enhancements:
Solved bugs:
- Incorrect display and behavior of default button in dialogs
- Double-clicking folders in the file tree to expand the tree, incidentally triggered an action to open a file.
- After deleting all file trees, a newly add tree only showed up after opening a source or restarting XMLSpear
- The filetree tab, which displays the top directory name, was not updated after a folder was selected as the new root.
- Small problems with the item names in the filetree popup menu in java 1.6
- Incorrect positions in the find-replace (especially concerning Windows users after a saving a document.
- Redundant extra line number in text editor
- Several XML formatting issues in the source view.
- Loss of linefeeds after editing text in tree tabel
- Incorrect behavior regarding to mixed elements with multiple text nodes
- Prefix initially not filled in dialog for inserting elements or attributes
New functionality:
- Move up possibility in file tree
- If you select a .xsd file in the tree, there will be a new option in the popupmenu to generate a XML instance from the selected schema
- A totally new find-replace dialog with the possibility to mark text.
- A find function for the tree table
- Improved support for mixed elements. You can switch to an advanced mode, where the textnodes will displayed in the tree.
- If a text has linefeeds or tabs you are not allowed editing the text in the table cell. This will be indicated by a special button which brings up a text editor.
- In edit mode, you will have a button in each cell to switch to a full functional tekst editor.
- If a value is part of an enumeration, it will be showed in the table. In previous versions the combobox was only showed in editMode.
- Xpath display of each selected element in the tree table view
- Insert and editing of CDATA and text nodes in the tree table view
- Improved schema support for enumerations and fixed values
- Unformat option in the XML source view
Updates:
- Alphabetical listing of elements in dialogs
- Collapse and Expand actions are now local to the selected node, instead of to the complete tree
- The warning message for large XML files is removed. If a XML file is displayed in the treetable, it will no longer be fully expanded. This will save a lot of load time. It is not a good idea to fully expand such a tree from the rootlevel. This will be slow or may cause an out-of-memory exception.
