[R] exportation of xml file from R

[Duncan Temple Lang]

BTW, the XML you show is not legal XML.
For instance, the element

   <Pr(>F)>NA</Pr(>F)>

is not a legal XML element name.

Similarly

  </anova:2>

is not a legal name since it is "2".
And anova:2 means an element with name 2 with (XML) name space prefix
"anova" (which must be declared previously)

As Gabor mentioned, StatDataML is one approach to generating
an XML representation of an R object.
Since the objects look related to fitted models, you might
also want to look at PMML (Predictive Model Markup Language)
as that is a more widely used standard.
