There are three Entry Helpers in XQuery mode of Text View: XQuery Keywords (blue), XQuery Variables (purple), and XQuery Functions (olive).
Note the following points:
|•||The color of items in the three Entry Helpers are different and correspond to the syntax coloring used in the text. These colors cannot be changed.|
|•||The listed keywords and functions are those supported by the Altova XQuery Engines.|
|•||The variables are defined in the XQuery document itself. When a $ and a character are entered in Text View, the character is entered in the Variables Entry Helper (unless a variable consisting of exactly that character exists). As soon as a variable name that is being entered matches a variable name that already exists, the newly entered variable name disappears from the Entry Helper.|
|•||To navigate in any Entry Helper, click an item in the Entry Helper, and then use either the scrollbar, mouse wheel, or page-down and page-up to move up and down the list.|
To insert any of the items listed in the Entry Helpers into the document, place the cursor at the required insertion point and double-click the item. In XQuery, some character strings represent both a keyword and a function (empty, unordered, and except). These strings are always entered as keywords (in blue)—even if you select the function of that name in the Functions Entry Helper. When a function appears in blue, it can be distinguished by the parentheses that follow the function name.
