Subject: [xsl] Choose-When-Otherwise Nesting Problem From: "Scott Downie" <sdownie@xxxxxxxxxxxxxxxxxxxx> Date: Wed, 21 Feb 2001 10:57:42 -0600 |
Hello! We're diving into XSLT and climbing the learning curve. At the moment, we're trying to become familiar with how to nest XSL commands. In the example I've attached below, we want to take an incoming stream of XML and display text depending upon what the incoming MaxAmount and MinAmount values are. If a particular alert is associated with a MaxAmount or a MinAmount, we want to display it. If both MaxAmount and MinAmount are null, we want to display "Any Change". This process is repeated for all the incoming alerts with the output format being altered (by the outermost choose condition) to display alternating background colors in the output list. When we actually try this, the very first MaxAmount or MinAmount is displayed. But if the first value is a MaxAmount (for example), no subsequent MinAmounts will appear. By the same token, if the first value is a MinAmount, no MaxAmounts will appear. And even if all of the MaxAmount and MinAmount input is null, the choose statement will never make it down to the otherwise branch that should display "Any Change". We must be nesting these commands in the wrong order, causing the process to 'stick' on the first MaxAmount or MinAmount. But we don't see a clear solution. Any help would be appreciated. Thanks!
