As this book goes to press, the current version of the XML specification is.
For the most part, you will only care that your documents are well formed. Well-formedness alone allows you to create ad hoc XML documents that can be generated, added to an application, and tested quickly. The bottom line? Well-formedness is mandatory, but validity is an extra, optional step.
The first thing we want to do is to create an XML document. Here it is again, with a few more nodes added to it: Example 1. It really is as good as we say it is--or your money back. As Figure 1. Notice the little minus signs next to some of the XML nodes? A minus sign in front of a node indicates that the node contains other nodes.
If you click the minus sign, Internet Explorer will collapse all the child nodes belonging to that node, as shown in Figure 1. Collapsing nodes displaying in Internet Explorer. View larger image. The little plus sign next to the first product node indicates that the node has children. Clicking on the plus sign will expand any nodes under that particular node.
In this way, you can easily display the parts of the document on which you want to focus. Now, open your XML document in any text editing tool and scroll down to the cost node of the second product. You should see an error message that looks like the one pictured in Figure 1. Error message displaying in Internet Explorer. Furthermore, it provides a nice visual of the offending line, a little arrow pointing to the spot at which the parser thinks the problem arose. Because Internet Explorer uses a non-validating parser by default remember, this means it only cares about well-formedness rules , it runs into problems at the end tag.
You now have to backtrack to find out why that particular end tag caused such a problem.
Open your XML document in an editor once more, and fix the problem we introduced above. Save your work and reload your browser. You should see an error message similar to the one shown in Figure 1.
Debugging a more complex error. At first glance, this error message seems a bit more obscure than the previous one. However, look closely and what do you see? Firefox is a popular open-source browser, and at the time this book went to print the latest version was 1. You can download a free copy from the Mozilla website. How do you do that? Well, there are a couple of options, listed below. All you have to do is visit the appropriate page, upload your document, and the parser will validate it.
Here is the most popular online parser. Viewing raw XML in Firefox. Using a Local Validating Parser Sometimes, it may be impractical to use a Website to validate your XML because of issues relating to connectivity, privacy, or security.
XML - Managing Data Exchange
Just download the package and install it by following the instructions provided. Be warned, however, that you will have to know something about working with Java tools and files before you can get this one installed successfully. This checks for well-formedness if the document has no DTD, and for well-formedness and validity if a DTD is specified.
Results of the validation will appear under the Results area, as illustrated in Figure 1. For most purposes, an online resource will do the job nicely.
If you work in a company that has an established software development group, chances are that one of the XML-savvy developers has already set up a good validating parser.
This project will help ground your skills as you obtain firsthand experience with practical XML development techniques, issues, and processes. It usually consists of the following components: A data back-end comprising XML or database tables that contains all your articles, news stories, images, and other content.
In Reader navigation works with a keyboard, mouse, stylus, or through electronic bookmarks. The Catalog Library records reader books in a personalized "home page", and books are displayed with ClearType to improve readability.
XML - Managing Data Exchange
A user can add annotations and notes to any page, create large-print e-books with a single command, or create free-form drawings on the reader pages. A built-in dictionary allows the user to look up words.
In August , Microsoft announced they were discontinuing both Microsoft Reader and the use of the. It also supports native SQL queries to be used with embedded databases.
There is a corresponding e-book reader. The Mobipocket Reader has a home page library. Readers can add blank pages in any part of a book and add free-hand drawings. Annotations — highlights, bookmarks, corrections, notes, and drawings — can be applied, organized, and recalled from a single location. Images are converted to GIF format and have a maximum size of 64K,  sufficient for mobile phones with small screens, but rather restrictive for newer gadgets.
Mobipocket Reader has electronic bookmarks, and a built-in dictionary. The reader has a full screen mode for reading and support for many PDAs , Communicators , and Smartphones. Mobipocket products support most Windows, Symbian, BlackBerry and Palm operating systems, but not the Android platform.
The site site's AZW format is basically just the Mobipocket format with a slightly different serial number scheme it uses an asterisk instead of a dollar sign , and. site has developed an.
A multimedia ebook is media and book content that utilizes a combination of different book content formats. The term can be used as a noun a medium with multiple content formats or as an adjective describing a medium as having multiple content formats.
The "multimedia ebook" term is used in contrast to media which only utilize traditional forms of printed or text books. Multimedia ebooks include a combination of text , audio , images , video , or interactive content formats.
Much like how a traditional book can contain images to help the text tell a story, a multimedia ebook can contain other elements not formerly possible to help tell the story. With the advent of more widespread tablet-like computers, such as the smartphone , some publishing houses are planning to make multimedia ebooks, such as Penguin.
The XML Data
Commonly known as a Newton Book  , but officially referred to as a Newton Digital Book  ; a single Newton package file can contain multiple books for example, the three books of a trilogy might be packaged together. The Newton package format was released to the public by Newton, Inc.
The format is thus arguably open and various people have written readers for it writing a Newton book converter has even been assigned as a university-level class project .
Newton books have no support for DRM or encryption. They do support internal links, potentially multiple tables of contents and indexes, embedded gray scale images, and even some scripting capability using NewtonScript for example, it's possible to make a book in which the reader can influence the outcome. An individual Newton Book may actually contain multiple views representing the same content in different ways such as for different screen resolutions. The format was developed to provide a platform-independent means of exchanging fixed-layout documents.
Derived from PostScript , but without language features like loops, PDF adds support for features such as compression, passwords, semantic structures and DRM. Because PDF documents can easily be viewed and printed by users on a variety of computer platforms , they are very common on the World Wide Web and in document management systems worldwide.
Because the format is designed to reproduce fixed-layout pages, re-flowing text to fit mobile device and e-book reader screens has traditionally been problematic. This limitation was addressed in with the release of PDF Reference 1. Third party viewers such as xpdf and Nitro PDF are also available. Mac OS X has built-in PDF support, both for creation as part of the printing system and for display using the built-in Preview application. PDF files are supported by almost all modern e-book readers, tablets and smartphones.
However, PDF reflow based on Tagged PDF, as opposed to re-flow based on the actual sequence of objects in the content-stream, is not yet commonly supported on mobile devices. Such Re-flow options as may exist are usually found under "view" options, and may be called "word-wrap". The first e-books in history were in plain text.
The plain text format doesn't support digital rights management DRM or formatting options such as different fonts, graphics or colors , but it has excellent portability as it is the simplest e-book encoding possible as a plain text file contains only ASCII or Unicode text text files with UTF-8 or UTF encoding are also popular for languages other than English.
The only potential for portability problems of ASCII text files is that operating systems differ in their preferred line ending convention and their interpretation of values outside the ASCII range their character encoding. Conversion of files from one to another line-ending convention is easy with free software. By convention, lines are often broken to fit into 80 characters, a legacy of older terminals and consoles.
Alternately, each paragraph may be a single line. When Unicode is not in use, the size in bytes of a text file is simply the number of characters, including spaces, and with a new line counting for 1 or 2.
For example, the Bible , which is approximately , words, is about 4 MB. Plucker is an Open Source free mobile and desktop e-book reader application with its own associated file format and software to automatically generate Plucker files from text, PDF, HTML, or other document format files, web sites or RSS feeds. The format is public and well-documented. Free readers are available for all kinds of desktop computers and many PDAs.
PostScript is a page description language used in the electronic and desktop publishing areas for defining the contents and layout of a printed page, which can be used by a rendering program to assemble and create the actual output bitmap. Many office printers directly support interpreting PostScript and printing the result. As a result, the format also sees wide use in the Unix world. Rich Text Format is a document file format that is supported by many ebook readers.
Its advantages as an ebook format is that it is widely supported, and it can be reflowed. It can be easily converted to other ebook formats, increasing its support. It is a proprietary raster image compression and binding format, with reading time OCR plug-in modules. The company scanned a huge number of Chinese books in the China National Library and this becomes the major stock of their service.
The detailed format is not published.
There are also some other commercial e-book formats used in Chinese digital libraries. The TomeRaider e-book format is a proprietary format. Several Wikipedias are available as TomeRaider files with all articles unabridged, some even with nearly all images.
Capabilities of the TomeRaider3 e-book reader vary considerably per platform: For Symbian there is only the older TomeRaider2 format, which does not render images or offer category search facilities.
Despite these differences any TomeRaider e-book can be browsed on all supported platforms.
Creating tables with Ibex
The Tomeraider website  claims to have over e-books available, including free versions of the Internet Movie Database and Wikipedia. The format is intentionally restricted to sequences of: An XML document consists of a sequence of human-readable characters, with no special additional codes or binary data. The purpose of a start-tag is to mark the point in the sequence of characters at which some element, of a type indicated by the tag name, starts, and the purpose of an end-tag is to mark where that element ends.
The purpose of an attribute specification is to add some extra information about an element occurrence beyond its name. But the XML standard says nothing at all about how elements or attributes should be named unlike, for example, HTML which defines a specific set of tags that must be used in a particular way in all documents , much less what their names mean. If the paragraphs are clearly marked, then a formatter can lay them out properly. If the place-names are clearly marked, a program can automatically pick them out to make a geographical index.
But this can really only be done reliably if we have some control over how tags are introduced into the document and where they appear.It includes advanced compressors optimized for low-color images, such as text documents. This data is contained in an XML file called bookdata.
CSS and Prince provide a number of page selectors for choosing which pages a rule applies to. Images can be included in XHTML and DocBook documents using the appropriate image elements, which are pre-defined in the default style sheets.
For example, If you have a large image that happens to occur at the end of the page, it could force a page break and leave a gap at the end of the previous page. The Mobipocket Reader has a home page library. Prince currently defaults to the RGB color space. A CMYK printer should print the gray level using only the black ink. The src descriptor can define the resource with a url function - an optional format function defines the format of the remotely fetched font.
It might be desirable to tie the footnote to the same page as the call - the prince-footnote-policy can be of help.
