I think it's usually better to just write the code so that it works
with any EOL marker, any such test as you suggest above will get
confused with the (not uncommon) case of files with inconsistent line
endings for example.


For example if you have a text file file.txt then

<xsl:param name="filelinest"
       select="tokenize(unparsed-text('file.txt'),'[\r\n]+')"/>

will give you a sequence of strings where any combination of U+000A or
U+000D counts as a separator.

True, bit it won't give you empty lines that are sequences of end-of-line sequences.


The regex I use for this purpose is:

<xsl:param name="filelinest"
           select="tokenize(unparsed-text('file.txt'),'\r?\n|\r')"/>

... which I'm pretty sure will give one empty lines when they exist.
