可以通过在CAM模板规则中指定printmessage表达式来处理这样的场景。
Such scenarios can be handled by specifying a printmessage expression in the CAM template rules.
可以替换XPath表达式、指令、模板或者导入的样式表模块，以及其他构造函数，替换可以在不同的层次上进行。
You might replace an XPath expression, an instruction, a template, or an imported stylesheet module, among other constructs, and the replacement might be a different granularity.
syntax接受一个转换表达式(由模板变量和常量表达式组成)并返回产生的语法对象。
Syntax takes a transformation expression consisting of template variables and constant expressions and returns the resulting syntax object.
这个XPath表达式的上下文节点是模板替换的元素，在这里是ATOM元素。
The context node for this XPath expression is the element that the template is replacing — in this case, an ATOM element.
基本理解XPath表达式、模板的匹配方式和xslt递归算法之后，就可以创建简短的可维护的转换。
A basic understanding of XPath expressions, how templates are matched, and XSLT recursive algorithms will result in the creation of small, easy, and maintainable transforms.
Sitebricks模板中的表达式就像JSP那样简洁，但却通过一个类型推断算法进行静态的类型检查。
Expressions in Sitebricks templates are just as concise as JSP, but are statically type-checked using a type-inference algorithm.
我将模板匹配从 /修改为Invoice，这样就不需要在每个XPath表达式的开头部分重复根元素名称。
I've changed the match on the template from / to Invoice so that I don't have to repeat this root element name at the start of each XPath expression.
但是调用命名模板需要更多的XSLT指令，调用函数则更紧凑而且很容易嵌入到XPath表达式中。
However, to call a named template requires more XSLT instructions, while to call a function is more compact and can easily be embedded in an XPath expression.
通常，组件本身就是表达式的上下文，这种情况下，模板表达式会引用那个组件。
The component itself is usually the expression context, in which case the template expression usually references that component.
然后，对从SQL表达式模板产生的SQL表达式应用聚合，形成度量的SQL表达式。
Then apply the aggregation function to the SQL expression resulting from the SQL expression template to form the SQL expression for the measure.
比方说，表达式中的变量引用将导致错误，即使元素确实位于变量有效的模板中。
For example, a variable reference in the expression results in an error even though the element is positioned in a template where the variable is in scope. Some key differences are.
第一个模板使用XPath表达式从
The first template uses an XPath expression to look up the value from the <http-params> section.
为了解决上述问题，您可能希望以某种方式在lookup模板中传递用于XSLTkey结果的XPath表达式。
