Subject: RE: [xsl] Parser implemented in XSL -- stack overflow From: Bill Cohagan <bill.cohagan@xxxxxxxxxxxxx> Date: Thu, 3 Apr 2003 07:09:18 -0600 |
Michael- You say: > xsl:apply-templates is a call, just like call-template, and it requires a new stack frame. So, the "problem" in my XSL is not that the style makes pushes necessary that "normally" woudln't be; rather it's that the processing of siblings in order causes there to be no pops until the end of the document -- thus the overflow. For my purposes this means I'll have to find an alternative approach to implementing the generated DFST -- which isn't a huge problem in this case. In the meantime I encourage you (and other XSL compiler designers) to consider implementing proper tail recursion in your compilers. I believe it is fairly straightforward, being a syntactic issue rather than one of determining the semantics of a particular call. (At least it's straightforward if you're doing recursive descent.) Thanks for helping me understand the problem. Regards, Bill XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
