Edit Mashup XPath Expressions in Advanced Mode

The Advanced Mode and Basic Mode buttons appear in block properties for built-in MashZone NextGen action blocks that use conditions, such as

Filter and

Join. They also appear in Advance Properties for Execute Conditions for all mashables and mashups, most of the built-in MashZone NextGen action blocks and any custom action blocks that enable conditional execution.

Basic mode is simply the existing properties you see for a block or execute condition. Advanced mode, however, allows MashZone NextGen developers to directly edit the XPath expressions for a condition.

Important: The advanced mode should be used with care by developers who are knowledgeable in XPath syntax. Editing XPath expressions directly can cause errors in the mashup.

Moreover, once a condition is in advanced mode in Wires, returning to basic mode completely removes the XPath expression and the condition.

To edit XPath expressions for conditions, simply click Advanced Mode in the Block Properties pane or the Advanced Properties tab.

Edit the expression as needed, following XPath syntax. For more information on XPath, see the XPath 2.0, XPath 2.0 functions and the XPath 2.0 Data Model specifications.
