Easy way to output a default value if <xsl:value-of/> selection comes back empty?

I am looking for a way to get my transformations to output a default
value from <xsl:value-of/> if a selected element doesn't exist or is
empty without having to have tons and tons of <xsl:choose/> blocks
everywhere. Is there a quick solution to this or am I going to have
to take the pain? (Also, suggestions on where else I should post this
question would be helpful.)

I think you need xsl:choose. Or write a named template that you call
(which of course in its body then has xsl:choose).

XPath 2.0 might make that easier as I think there you can write some if
expression alike
<xsl:value-of select="if (text()) then text() else 'Maho'" />
You can try XSLT 2.0/XPath 2.0 with Saxon from http://saxon.sf.net/.

I'm trying to create an XSL transformation that will strip out development-specific attributes from deployment descriptors and other XML files.

For ASP.Net/C Sharp I have an XML file and an associated XSL file. I am using the System.Web.UI.Controls.Xml control to render the resulting HTML. This seems to work fine with one slight drawback. I cannot seem to find a way to attach to the events generated by controls generated by the XSL transformation. I have tried the FindControl on the page, but it does not find the control. There must be something I am doing wrong because I...

I can't figure out how to do this because the tags have to be properly nested... and I dont have much XSL experience. Say I'm generating an HTML tag in my XSL file, and for one of it's attributes, I want to put the value of an XSL tag... for example: XSL file... ...... <xsl:template match="/" <div class = "{value of XSL tag 'entry' goes here}" > hello world</div>
