Use '@(...)' Expressions in XML Attributes


When using "@(...)" expressions in XML attributes as part of an policy statement, do I need to worry about string quotations?



If you are using a "@(...)" expression in XML attributes as part of an policy statement, and string literals are used in the "@(...)" expression, the syntax of the final policy statement is confusing:

For example, the following "set-variable" policy statement uses a "@(...)" expression as part of an attribute value to set a new variable to be used later:

<set-variable name="message" value="@("Hello world!")" />

From XML syntax point of view, the above XML element is actually not valid. Because the XML attribute value can not have nested quotes.

But has no problem take the above XML statement.

It could be that is processing the @(...) expression first, before processing the XML element.
