An XML document is not required to have a corresponding DTD. However DTDs are introduced into XML documents using the document type declaration ( i.e. Introduction. In this section we introduce the notion of semi-structured data . XML. XML Document Type Declaration, commonly known as DTD, is a way to An XML DTD can be either specified inside the document, or it can be kept in a.
Handling the union type 1. You use the Tags panel to apply element tags to content that you plan to export to XML. Storing person phone 3 Semistructured Data with Stored. The recipe element, in turn, is the parent of elements called recipename and ingredients. IDREFS attributes are mapped by creating a new table contains a foreign key to the referenced table and a foreign 2.
The Tags panel lists tags for elements. You can import, export, add, delete, and rename tags. You use the Tags panel to apply element tags to content that you plan to export to XML, and to apply tags to frames before importing XML content into them.
You use the Tags panel to apply element tags to content that you plan to export to XML. To share XML data with others, you need to agree on a standard set of tag names and element attributes so that everyone in your group uses and applies tags the same way.
A DTD file provides a set of elements and attributes for members of the group to use. It also defines the rules about where elements can appear in the structural hierarchy. For example, the DTD file may require the Title element to be a child of the Story element because the title is supposed to appear inside the story; if you tag a title without tagging the story it appears in, the DTD file marks the Title element as invalid.
This process is called validating. This imports the element names from the DTD into the Tags panel. Others who have loaded the same DTD file have the same element names, which ensures that everyone in the group uses the same elements. You can view the DTD file in InCopy and validate stories against it to ensure that tags have been applied correctly.
Each rule consists of at least one condition and at least one action. A rule evaluates the XML data against the conditions, and if a condition is met, then it takes the appropriate action.
For example, an XML rule can specify that whenever the Paragraph element appears under the Subhead element a condition , a specific style an action is applied; or that whenever the Product element a condition appears, a new frame is created and a product image is imported actions.
Merge can replace the existing structure, whereas append adds to any existing structure. In both cases, it is important that the root element is not associated with a text frame.
Either use the default element named "Root" or rename this element based on your current workflow or requirement as needed, again being sure that it is not associated with a text frame.

So we create a new table editor conf, person tact, author, cite id, cite format , person code, id, fn, ln, and remove the editor attribute form conf table, so conf email, phone. Mapping collection types 2. Handling the union type 1. If there is a table corresponding to the collection type In this step, if we find more than one attribute that may , then add a foreign key refers to the table that represent or be NULL in a table say a1, a2, do the following step contains its parent.
Replace them with two attributes, one of them as 2. Else create a new table corresponding to the collection a flag attribute and the second for values its name type, and add a foreign key refers to the table that represent is a1 a2 or contains its parent. Add the flag attribute to the key of the table.
If the parent of the collection type say e is an attribute Example 8. So the paper per. Capturing order specified in the XML model 2.
