Select the sentence that begins Check with Jo (the only remaining untagged text in the class element). An X next to the classlist and class elements indicates that the structure is not valid according to the schema rules, and three dots under the classroom element and at the end of the class element tell you that an element is missing.Ī ScreenTip tells you that untagged text is not allowed in the class element all text must be enclosed in valid start and end element tags. It is helpful to have non-printing characters displayed when you are selecting paragraphs for tagging.Īs you tag each element, it appears in the Elements In The Document box. Then you will attach a schema to a document, tag document elements to create valid structure, and save that file as an XML file. In this exercise, you will first save a document in XML format.
Generally, companies employ a specialist with in-depth knowledge of XML to create custom schemas, but anyone can use an existing schema to tag a Word document and save it as an XML file. Word uses the schema to validate the document content and prompts you when content has been incorrectly tagged. The schema might also define formatting attributes that you can apply to text within specified elements. For example, a book might be divided into parts that can each contain chapters, which in turn can contain topics, which in turn can contain a heading, paragraphs, numbered and bulleted lists, tables, and other elements. The schema is an additional file that describes the structure allowed in the document, including the names of structural elements and what elements can contain what other elements. If you want more control over the tagging of a document, you can attach an XML schema to it. You can also open it in an XML editor such as XMetal, or as a plain text file in a text editor such as Notepad. You can open and edit an XML file in Word, in the same way you can an HTML file. During conversion, Word tags the file based on its styles and other formatting and saves it with an. However, with Word 2007, anyone can participate in these processes by creating a Word document and then saving it as an XML file. However, instead of being fixed like HTML, XML can be customized (extended) to store data so that it can be used in many ways in many environments-for example, as text, in a database or spreadsheet, or as a Web page.Ĭreating sophisticated, multi-purpose XML files can involve highly technical processes that are designed by experienced systems analysts and application developers. Extensible Markup Language (XML) is another subset of SGML. HTML is a small, fixed subset of Standard Generalized Markup Language (SGML), a comprehensive system for coding the structure of text documents and other forms of data so that they can be used in a variety of environments. As we mentioned earlier, basic Web pages are coded in HTML so that they can be displayed in a Web browser.
