Chapter 11: XML
Adobe® InCopy® is one of many applications that can produce and use XML. After you tag content in an InCopy file,
you save and export the file as XML so that it can be repurposed in InCopy, Adobe InDesign®, or another application.
Working with XML
About XML
XML (Extensible Markup Language) is a way to repurpose data in a file or automate the process of replacing the data
in one file with data from another file. XML employs tags to describe parts of a file—a heading or a story, for example.
These tags mark data so it can be stored in an XML file and handled appropriately when it is exported to other files.
Think of XML as a translation mechanism for data. XML tags label text and other content in a file so that applications
can recognize and present the data.
Extensible language
XML is considered an extensible language because individuals create their own XML tags—they can create one tag for
each type of information that they want to repurpose. XML tags don't carry information about how data is supposed
to be displayed or formatted. XML tags are strictly for identifying content.
In InCopy , for example, you can create a
tag and assign it to each first-level heading in a document. After
Heading1
you save the document as an XML file, the Heading1 content can be imported and put to use—by any application that
can read XML—as a web page, printed catalog, directory, price list, or database table.
Adobe InCopy is one of many applications that can produce and use XML. After you tag content in an InCopy file,
you save and export the file as XML so that it can be repurposed in another InCopy file, InDesign file, or another
application.
In InCopy , you can create XML tags and tag parts of a document even if you're not experienced with XML. InCopy
handles XML programming behind the scenes and creates the XML for you when you export a document in XML
format.
Important: Do not confuse XML tags with InCopy tagged text. For more information about tagged text, which is a
different method of exporting and importing InCopy content, view the Tagged Text PDF at
www.adobe.com/go/learn_id_taggedtext_cs4_en(PDF).
XML data structure
The element is the building block of XML data; an element is data that has been tagged. In XML files, elements are
nested within other elements to create a hierarchical structure for the data.
You can see the structure of XML data in the Structure pane, which displays the hierarchy and sequence of elements.
In the XML structure, child elements are contained by parent elements, which in turn may also be child elements. Or,
seen from the other direction, parent elements contain child elements, and these child elements may in turn be parent
elements to other child elements.
For example, in the following image, you can see a
element that contains (is the parent of) a
element.
