System.OutOfMem oryException on Large Files)

[Mohd Banat]

hello,

I get XXX when I run the following code (if and only if the outcome of
transformation is beyond 20 MB)

With _Xslt

.Load(XslFile)

.Transform(XmlD ocument, Nothing, MyWriter, Nothing)

End With

If I run this in .NET 2.0 Beta 2, it gets on and it's much faster as well.
If run the same on MSXML 4.0, it's works and it's much faster too.

Is this a known issue in .NET 1.1 ? Is there a way around it? or do I have
to switch to MS XML 4.0 for now?

If you are using XslCompiledTran sform instead of XslTransform in .NET
2.0 then you should certainly see much better performance. Or are you
using XslTransform in .NET 1.1 and .NET 2.0 and then see much of a
performance difference?

A workaround might depend on the stylesheet and the XML input and
finding more efficient ways to transform which could involve changing
the stylesheet, breaking up the input, breaking up the output.

Well,

first, by XXX I meant System.OutOfMem oryException (sorry).

second, I'm not xml/xsl/xslt guru, but I beleive that what we have is fairly
simple, and I'm not sure if it can be optimized. We're trying to generate
WordML out of some database queries. The output XML is WordML, and cannot be
chunked easily, I assume.

Is there anything that we can check? like an article on optimization (if
that's the way to go)?

How come .NET 2.0 and XML 4.0 has no problem?

Hi Mohanmmed,

Is the Xml document very large and the XSL transformation comsumes a lot of
resource? Yes, as I know, the MSXML, .NET xml 1.1 and 2.0 has a lot of
difference. .NET xml 2.0 has a lot of optimizations than 1.1. And the
implementation of .NET xml and MSXML is totoally different. It's hard to
reproduce this error on my machine, even with a large xml doc. In this
case, I suggest you try to contact Microsoft PSS for this issue. If this is
really a bug, the service will be free of charge.
