The list archives did not seem to contain an XSLT stylesheet that could
index an XML file, but I may have missed it. Is it practical to write my own
XSLT 2 indexing stylesheet? If so, I have a bilingual XML file that I want
to index. My assumptions are that I must get rid of the punctuation
properly, then isolate the words, sort them, remove stop words, and so on.
To get started, I need a bit of help. All of the phrases are found in two
attributes: @czech and @eng.
Three questions:
(1) I am aware from Michael’s book that regex expressions may be used in the
replace() function, but I do not know how to write that regex expression. I
would like to remove all the punctuation from a phrase as follows: for
everything except a hyphen [-], replacement should be with an empty string;
the hyphen should be replaced with a single space.
(2) I assume that to get rid of extra spaces (if any), I can use a construct
like: normalize-space(replace(@czech, ‘some regex expression’)).
(3) I assume that tokenize(normalize-space(replace(@czech, 'some regex
expression'))) will permit me to write out a list of the words found in
those attributes to an XML document. I am not completely clear as to what
tokenize() returns, or how to access that return.
I would appreciate any comments, and especially the construction of the
regex expression needed.
Thanks,
Mark
