How Data is Represented on the Canvas

Data is represented by glyphs that contain an XPath expression. The composition of these XPath expressions varies based on the context of the component in which the data is being included. The glyph might contain just an element name, or it might display a longer XPath expression if it represents data whose context is not established by the containing component.

Example

The context for the table component shown in Figure 449 is the video repeating element from the videos.xml document. You can see this if you select the table in the canvas and look at either the

The following table shows the different types of XPath expressions you might see in an XML Publisher report.

Table 128. Explanation of XPath Expressions in Data Glyphs

Data Glyph	Contains	Description
	The current context	The XPath expression for context is a dot. To make this easier to see in the glyph, Stylus Studio adds the element name in parentheses following the dot.
	An element (or attribute) name	If the context is established by the containing component, the data glyph contains only the element or attribute name.
	A full XPath	If the context for the data is not established by the containing component, Stylus Studio displays the full XPath needed to resolve it.
