The two things wrong with your solution are:
(a) you're matching any sequence of letters that could be a roman numeral,
without looking at the context, hence matching the IX in APPENDIX.
(b) you're only matching the first thing in each element that looks like a
roman numeral
The second is easily fixed: don't use an anchored regex in analyze-string
like this
regex="^(.*?)([IVXL]+)(.*?)$"
Instead use an unanchored regex
regex="([IVXL]+)"
and add an xsl:non-matching-substring element that copies unmatched
substrings across unchanged (or case-converted if you want).
Problem (a) is much harder. You can get a fair way by requiring the sequence
of IVXL to have non-letters before and after it. But you'll still be
matching the word "ILL" as a roman numeral when it clearly isn't. Like all
up-conversion tasks, though, it's very much up to you how much time you want
to spend fine-tuning the patterns and rules that you define.

Subject: [xsl] Using analyze-string to catch roman numerals?
Hello all,
Given the following input:
<root>
<head>CHAPTER II. THE WRECKED FOUNDATIONS OF DOMESTICITY</head>
<head>PROBLEMA. HELOISE XXIX.</head>
<head>Selected Letters</head>
<head>The Second Part of Henry IV.</head>
<head>VIII</head>
<head>APPENDIX VII</head>
<head>Appendix VII</head>
<head>APPENDIX</head>
<head>CALVIN XVII</head>
<head>ILLUSTRATION</head>
</root>
and the following template:
<xsl:template match="head">
<xsl:choose>
<xsl:when test="not(matches(.,'^(.*?)([IVXL]+)(.*?)$'))">
<xsl:value-of select="lower-case(.)"/>
</xsl:when>
<xsl:when test="matches(.,'^(.*?)([IVXL]+)(.*?)$')">
<xsl:analyze-string select="."
regex="^(.*?)([IVXL]+)(.*?)$">
<xsl:matching-substring>
<xsl:value-of
select="lower-case(regex-group(1))"/>
<xsl:value-of
select="upper-case(regex-group(2))"/>
<xsl:value-of
select="lower-case(regex-group(3))"/>
</xsl:matching-substring>
</xsl:analyze-string>
</xsl:when>
<xsl:otherwise/>
</xsl:choose>
</xsl:template>
I'm trying to use analyze-string to do the following:
Test for a roman numeral. If there isn't one, lower-case(.).
If there is one, break (.) into its roman numeral and
non-roman numeral parts, lower-case()ing the latter.
The output I get is:
chapter II. the wrecked foundations of domesticity
probLema. heloise xxix.
selected Letters
the second part of henry IV.
VIII
appendIX vii
appendix VII
appendIX
caLVIn xvii
ILLustration
When what I want is this:
chapter II. the wrecked foundations of domesticity
problema. heloise XXIX.
selected letters
the second part of henry IV.
VIII
appendix VII
appendix VII
appendix
calvin XVII
illustration
Between my relative inexperience with both regexes and XSLT,
thanks for any help!
Tony
