xml - XSL transformation from EAD to MARC skips over 2nd subject term -
i have strange problem. have xml documents encoded in ead i'm transforming marc records library catalog. there section of ead document looks this:
<controlaccess> <list type="simple"> <item><subject encodinganalog="650" source="lcsh">prisons -- history -- 19th century</subject></item> <item><subject encodinganalog="650" source="lcsh">prisons -- statistics -- history -- 19th century</subject></item> <item><subject encodinganalog="650" source="lcsh">prisons -- statistics -- term 1 -- history -- 19th century</subject></item> <item><subject encodinganalog="650" source="lcsh">prisons -- statistics -- term 1 -- term 2 -- history -- 19th century</subject></item> </list> </controlaccess> what code correctly pull out each item/subject , create marc field each one, , each term that's separated "--" gets put separate subfield (either a, x, y, or whatever).
the code if there 1-3 terms in single subject element, if there 4 or more terms, second term gets left out entirely , rest of terms (from third 1 on) extracted properly. can't figure out why second term gets skipped on if there 4+ terms. that's i'd figuring out.
i'm using xsl 1.0 , subject portion of code looks this. parameter gets called main template.
<xsl:template name="subject_template"> <xsl:param name="string" /> <marc:datafield> <xsl:choose> <xsl:when test="contains($string, '--')!=0"> <xsl:variable name="tmp1" select="substring-before($string, '--')" /> <xsl:variable name="tmp2" select="substring-after($string, '--')" /> <marc:subfield code="a"> <xsl:value-of select="$tmp1" /> </marc:subfield> <xsl:call-template name="subject_tokenize"> <xsl:with-param name="string" select="$tmp2" /> <xsl:with-param name="type" select="'x'" /> </xsl:call-template> </xsl:when> <xsl:otherwise> <marc:subfield code="a"> <xsl:value-of select="$string" /> </marc:subfield> </xsl:otherwise> </xsl:choose> </marc:datafield> </xsl:template> here tokenize template, hundreds of lines long. tried include necessary/relevant problem.. 4 variables in beginning (genx, etc) pull huge list of terms determine subfield code should be.
<xsl:template name="subject_tokenize"> <xsl:param name="string" /> <xsl:param name="type" /> <xsl:variable name="genx"> <xsl:call-template name="genx" /> </xsl:variable> <xsl:variable name="geny"> <xsl:call-template name="geny" /> </xsl:variable> <xsl:variable name="formlist"> <xsl:call-template name="formlist" /> </xsl:variable> <xsl:variable name="geoglist"> <xsl:call-template name="geoglist" /> </xsl:variable> <xsl:if test="contains($string, '--')!=0"> <xsl:variable name="str1" select="substring-before($string, '--')"/> <xsl:variable name="str2" select="substring-after($string, '--')"/> <xsl:if test="contains($str2, '--')!=0"> <xsl:variable name="newstr2" select="substring-after($str2, '--')"/> <xsl:variable name="tmpvar" select="substring-before($str2, '--')"/> <xsl:choose> <xsl:when test="testsomething"> stuff </xsl:when> <xsl:otherwise> <xsl:if test="contains($geoglist, translate($str1, '.', ''))!=0"> <marc:subfield code="z"> <xsl:value-of select="$str1"/> </marc:subfield> <xsl:if test="contains($formlist, translate(substring-before($str2, '--'), '.', ''))!=0"> <marc:subfield code="v"> <xsl:value-of select="substring-before($str2, '--')"/> </marc:subfield> </xsl:if> <xsl:if test="contains($geny, translate(substring-before($str2, '--'), '.', ''))!=0"> <marc:subfield code="y"> <xsl:value-of select="substring-before($str2, '--')"/> </marc:subfield> </xsl:if> <xsl:if test="contains($genx, translate(substring-before($str2, '--'), '.', ''))!=0"> <marc:subfield code="x"> <xsl:value-of select="substring-before($str2, '--')"/> </marc:subfield> </xsl:if> <xsl:if test="contains($formlist, translate(substring-before($str2, '--'), '.', ''))=0 , contains($genx, translate(substring-before($str2, '--'), '.', ''))=0 , contains($geny, translate(substring-before($str2, '--'), '.', ''))=0"> <marc:subfield code="z"> <xsl:value-of select="substring-before($str2, '--')"/> </marc:subfield> </xsl:if> </xsl:if> <xsl:if test="contains($formlist, translate($str1, '.', ''))!=0"> <marc:subfield code="v"> <xsl:value-of select="$str1"/> </marc:subfield> </xsl:if> <xsl:if test="contains($geny, translate($str1, '.', ''))!=0"> <marc:subfield code="y"> <xsl:value-of select="$str1"/> </marc:subfield> </xsl:if> <xsl:if test="contains($formlist, translate($str1, '.', ''))=0 , contains($geny, translate($str1, '.', ''))!=0"> <marc:subfield code="x"> <xsl:value-of select="$str1"/> </marc:subfield> </xsl:if> <xsl:if test="contains($geoglist, translate($str1, '.', ''))=0"> <xsl:if test="contains($formlist, translate(substring-before($str2, '--'), '.', ''))!=0"> <marc:subfield code="v"> <xsl:value-of select="substring-before($str2, '--')"/> </marc:subfield> </xsl:if> <xsl:if test="contains($geny, translate(substring-before($str2, '--'), '.', ''))!=0"> <marc:subfield code="y"> <xsl:value-of select="substring-before($str2, '--')"/> </marc:subfield> </xsl:if> <xsl:if test="contains($geoglist, translate(substring-before($str2, '--'), '.', ''))!=0"> <marc:subfield code="z"> <xsl:value-of select="substring-before($str2, '--')"/> </marc:subfield> </xsl:if> <xsl:if test="contains($geoglist, translate(substring-before($str2, '--'), '.', ''))=0 , contains($geny, translate(substring-before($str2, '--'), '.', ''))=0 , contains($formlist, translate(substring-before($str2, '--'), '.', ''))=0"> <marc:subfield code="x"> <xsl:value-of select="substring-before($str2, '--')"/> </marc:subfield> </xsl:if> </xsl:if> <xsl:call-template name="subject_tokenize"> <xsl:with-param name="string" select="$newstr2"/> <xsl:with-param name="type" select="'x'"/> </xsl:call-template> </xsl:otherwise> </xsl:choose> </xsl:if> my output looks this:
=650 \0$aprisons $x history $x 19th century =650 \0$aprisons $x history $x 19th century =650 \0$aprisons $x term 1 $x history $x 19th century =650 \0$aprisons $x term 1 $x term 2 $x history $x 19th century the first 650 field correct. following 3 missing second term, "statistics." example , has been replicated different terms, different ordering of terms, and/or different quantity of terms. assume problem lies in xsl code showed because that's part of code should affecting example provided. if nobody finds errors in xsl snippet, perhaps take @ full xsl.
update: here link (https://drive.google.com/folderview?id=0b647oe0wvd5-rffpmjhqsjk3cve&usp=sharing) of files. includes entire xsl , xml, additional xsl gets imported, resulting output mrc file, , txt version of mrc file easier viewing.
