[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] help with recursive function
 Hi,
I'm having a problem with a recursive function in 2.0.
I'm iterating through the value of a node that is tokenized on spaces. I
normalize the 'word' to lower-case and remove an 's if it exists. Then check it
against a library xml file (spellingBee.xml), if the 'word' isn't listed then
just upper-case the first letter and leaving the rest as is; otherwise replace
the 'word' with the corrected spelling in the spellingBee.xml. Finish by
concatenating new 'word' with the value of g_AposS. That was simple enough to
create but I decided to take it one step further and check the current 'word'
for a simple set of delimiters (-/\); doing this to keep down the number of
entries in spellingBee.xml. Then start ripping it apart into two pieces: before
the delimiter and after the delimiter. The 'word' before the delimiter would be
checked against spellingBee.xml and the rules mentioned above would be applied.
The bit after the delimiter would be tossed back into the function by calling
the function again. That is when I receive the following error message:
[xslt]

[xslt] original headline :: MEET THE BEATLES
ABC's-A.B.C./A.b.c.'s-ABC\abc's\nbc/n.b.c.'s

called in cleanUp.xsl
<xsl:variable name="l_TokenizedString" select="tokenize($l_HeadTemp, ' ')" />
<xsl:for-each select="$l_TokenizedString">
<!-- line 259 mentioned in error message -->
<xsl:value-of select="concat(f:f_UpperLowerCaseFix(.), if (not(position() =
last())) then ' ' else '')" />
</xsl:for-each>
spellingBee.xml looks like the following
<fixCase>
<word>
<lowerCase>abc</lowerCase>
<corrected>ABC</corrected>
</word>
<word>
<lowerCase>a.b.c.</lowerCase>
<corrected>A.B.C.</corrected>
</word>
</fixCase>
The function itself
<xsl:function name="f:f_UpperLowerCaseFix">
<xsl:param name="p_String" />
<!-- this variable actually exists in a global variables file and is only
defined here for posting on XSLT mailing list -->
<xsl:variable name="g_AposS">'s</xsl:variable>

<xsl:value-of select="f:f_UpperLowerCaseFix($l_StringAfterDelimiter)" />
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="concat(upper-case(substring($l_String, 1, 1)),

<xsl:value-of select="f:f_UpperLowerCaseFix($l_StringAfterDelimiter)" />
</xsl:otherwise>
</xsl:choose>
</xsl:otherwise>
</xsl:choose>
</xsl:function>
The desired output from the sample node above should look like
input: MEET THE BEATLES ABC's-A.B.C./A.b.c.'s-ABC\abc's\nbc/n.b.c.'s
output: Meet The Beatles ABC's-A.B.C./A.B.C.'s-ABC\ABC's\nbc/n.b.c.'s
Any help will be appreciated.
