XML Decision Trees

Text
Arbitrary Text Files with indentation Buzz contains cross file (cross internet) xml search, XLINK and link This is coded as an external command also: xsearch "something to search for" "filename" "casesensitive(0 or 1)"

     This will recursively search and create a set of xlinks into the web
     caveat coder: There is no depth limit

It supports the subset of xlinks where the path elements are referenced by offset only This currently only works under linux with the sabcmd secondary to speed considerations Outlines are syntactically compatible with Userland Buzz and Userland have overlapping functionality. With Peerkat and Buzz one can have Userland functionality on Linux or anywhere Python runs Outlines can be editted in structured manner or free form (text edittor) XML
Buzz can create its schema by example. Give it a set of files and it will produce a schema Complete with values for the attributes XML can be transformed to multiple modalities using XSL EG Export you XML as a spreadsheet, Bibliography, XSL
Buzz has a schema for XSL and supports accurate white space preservation Buzz can export,import save and send to the browser any xml file passed thru XSL For example Buzz renders to HTML using the format you see here but you can render using many formats including the "standard" Userland formats Choose render to browser and then the opml2smart.xsl file Buzz can pass xml thru xsl:fo via FOP HTML
Buzz has a schema for html/ xhtml
Speed
Buzz is faster than Userland, Xeena and JOE by 2-10 times The 3000 line Buzz source OPML file takes 15 seconds to load in Userland on a PIII 650 The same file takes 1.5-2 seconds in Buzz Interacting with XML on the Web
I use Buzz to do all my Pubmed queries in XML You can exchange them with Endnote via the XSL rendering facilities You can do RSS queries and view the results in Buzz and render them with XSL to a browser Talk to a Manila XMLRPC server

Installation
Necessary
The minimal installation will allow editting and saving opml and xml Download and Install python 2.1
http://www.python.org
If you plan to use manila install xmlrpclib http://www.pythonware.com/downloads/xmlrpc-0.9.9-010226.zip Download and install wxpython/wxwindows http://sourceforge.net/projects/wxpython/ If on windows:
Download and install cygwin
http://sources.redhat.com/cygwin/download.html Don't install the python for cygwin component Download buzz.tgz to /usr/share
buzz.tgz
cd /usr/share ; tar xzvf buzz.tgz
cp buzz.cfg.unix (or buzz.cfg.win) to ~/buzz.cfg cd /usr/share/buzz
chmod +x
cp buzz /usr/bin
vi ~/buzz.cfg
Configuration File

     first line is buzzdir a "shared directory". For example:
      nix
       /usr/share/buzz/
      win2k
       e:\\buzz\\
      win98
       e:\buzz\
     next line is the command that will "expand"/open any file
      explorer.exe on windows
      I use konqueror on linux
     next line is a temporary directory
     next line is a command to execute scripts
      Under windows this should be the cygwin bash command
       E.G. bashcmd="e:\\cygin\\bin\\bash --login -i "
     The next line is a configuration switch to turn on free form editting of XML while a schema is set.
     The next line is the "Home" file
     Next is your manila site
     Next is your manila username

Under windows a shortcut can be created with this command Properties of shortcut
D:\cygwin\bin\bash.exe --login -c /usr/bin/buzz Verify that the HOME environment variable is set Optional
These functions are necessary for importing, exporting, printing etc Install Java 1.3 or greater
http://www.sun.com
Download and install instant-saxon
http://saxon.sourceforge.net
Download and install sabcmd
http://www.gingerall.com/charlie/ga/xml/d_sab.xml Download and install FOP
http://xml.apache.org/fop/
You'll need to modify the fop script to point to the installation directory of fop Download and install tidy
http://www.w3.org/People/Raggett/tidy/ Schemas
Schemas are currently implemented at a crude level and use a modified BNF syntax However, that is ameliorated by the schema generator. It builds schema from xml files by example Use the schema from example option in the XML menu This is a work in progress. I recommend that you edit the schemas generated to validate their structure
The syntax is: tag | required children | optional children Double quoted elements are assumed to be text, underscores are translated to spaces You must order the file in dependency tree order with the leaves first and the root last schemas should be named foo.schema. Files created with the schema should be named baz.foo (for the foo schema). and placed in the buzzdir Quickstart
The keys to editting OPML or XML in buzz are the keys that insert, move, and edit elements

Inserting
The Right Mouse button opens a menu F5 inserts a new element at the level above F6 inserts a new element at the current level F7 inserts a new element at the level below Ctrl-P Inserts data from other programs that you've copied into the tree
Moving
Home: moves the current item up the list of elements in the tree End moves the current item down Ctrl-C Copies an element or tree into a list of previously copied or cut elements Ctrl-X Removes an element or tree in the the list of previous copies Ctrl-V Inserts <Insert> Inserts the most recent element from the list of previous copies and makes the next oldest item the most current
Editting
Hit the return on the current element to edit it To undo an edit of an element while editting, hit the escape key ChangeLog 7/27/01 - First Schema Validating Version 8/21/01 - Switched to Sax2 parser from Expat 8/31/01 - Added xsl:fo functionality and compatibility 9/01/01 - Added Cross File XML Search and XLINK functionality 9/14/01 - XLINK history added. Schema generation from GUI 10/19/01 - Added Toolbar and Popup on Right Click 11/2/01 - Added Preliminary Manila Functionality 11/15/01 - Added Free Form Text Editting of Outlines Background Buzz is an XML/OPML editor based on Woody, Radio Userland and Xeena It Run's on Windows and Linux and should run anywhere wxwindows and python do. Mouse Left Click: On Text: Select; On Button: Expand Double Click: Expand Node Right Click: Popup Menu Menus This is out of date File Menu Open: Opens an XML File New OPML: Choose Recent: 10 recent files are maintained the most recent file is opened by default Choose Recent: 10 recent URLS Open URL: Open an XML file at an arbitrary URL Print OPML: Prints to from HTML Version. Places images inline Webify: Like print except centralizes external references into directory of document Save Save As: Save a copy as Save HTML Exit Import Menu Import: Import a text file as an indented Outline Export: Export OPML as indented text Import HTML Outline: Import MS word html outline file Import / Export ...: Imports and exports Lpro, Shadow and MS Word documents MS Word import and export works via HTML as an intermediary format In other words use Save As HTML in MS Word prior to importing Export HTML Outline: Useful for interacting with MS products like Word If you open a file exported as an HTML Outline Word will open it as an outline This is especially useful for interacting with Powerpoint for slides
Rendering
Buzz is setup to render XSL and XSL:FO in place, to a browser, file, acrobat etc Render Directory This will render all the OPML files in a directory as HTML and create a document with links to all the files Edit Menu Paste Clipboard: Converts clipboard text to OPML and inserts at highlighted node Insert URL Insert Image Insert File Insert File from URL Find Item Find and Replace Xsearch This starts a text search that will procede across any LINK,XLINK,HREF,URL and returns the result as a file of XLINKS XML Open XML This differs from Open in that characters are forced into ISO-8859-1 and long text blocks are broken word wrapped to less than 200 character blocks. New XML Webify XML: Display XML as HTML Document Preview Decision Tree: Shows an HTML version of a DT schema Save as XML It is easy to mix XML and OPML when editting OPML files Using this converts all OPML elements to XML on the presumptions: Outline items are tag names or attributes Attributes come before children and anything with the = sign is an attribute Text elements are not assumed and must be created using the appropriate keys New from schema: create a document using schema layout Set XML Schema: Loads a BUZZ specific schema to appropriately structured XML X Favorites: Set of XLINK favorites Delete Favorites Add Favorite Schema from example: Creates a buzz schema from a set of XML files Schema from example with attributes: as above but includes values of attributes Options Toggle Find and Replace: Useful for interactive find and replace Toggle Case sensitive find: By default find is not case sensitive Toggle Free Form XML Mode: While a schema is active allows arbitrary XML to be entered Can be set from the config file Toggle Continous text entry: When set to 1 will continuously enter text into tree. Exit with ESC key Default Keys Left/Right/Up/Down: Navigate Tree Ctrl-R: Open Recent File F1: [s]ave F2: Copy Node F3: Repeat Current Find Ctrl-F: Find below current node Ctrl-C : Copy Node Copies into the cut buffer ring Allows one to select multiple items and paste them in back somewhere else F4: Open node as URL F5: Open a node next to my parent F6: [o]pen a node at the same level F7: open a [c]hild node F8: Goto last selected node Useful under Windows where alpha keystrokes jump to nearest node that starts with that key Useful under wxGTK because editting text deselects item Ctrl-J: Join Node with next sibling Shift-J: Join Node with first child F9: Toggle between most recent files F10: Expand/Collapse everything to depth set in configuration file F11: Expand URL below current Item F12: Insert an OPML/XML file below the current Item Ctrl-A: open attribute <enter>: edit node text <Home>: Move Node Up <End>: Move Node Down Ctrl-X or <Delete>: Cut branch to buffer Ctrl-V :paste into tree from buffer <Insert> or Ctrl-B: Repeated use will progressively insert the cut ring <space>: expand or collapse branch Ctrl-T: open child [t]ext node <up>/<down>: up/down visible nodes <left>/<right>:Parent/Child of current node PgUp/PgDn: Move Fast Command Line Options First item on line is assumed to be an XML file Second Item is optional. 0 turns off highlighting Crash Recovery Buzz copies the file to filename~ before saving for crash recovery sourceforge.png
