XSLT Transformation failed

[Sandeep Singh]

Hi Team,

I have an xslt code in 2.0 version and this is validated and well form and not any issue in oxygen editor or saxon parser for transformation or any kind of operation but i have use this xslt in through lxml and try to transform our file through xslt function i have get e below error:

Traceback (most recent call last):
  File "C:/XSpec_Create/test/3-may-2022/a - orig.py", line 13, in <module>
    xslt_transformer = ET.XSLT(xslt_doc)
  File "src\lxml\xslt.pxi", line 412, in lxml.etree.XSLT.__init__
lxml.etree.XSLTParseError: xsl:value-of : could not compile select expression 'format-number(index-of(('jan', 'feb', 'mar', 'apr', 'may', 'jun', 'jul', 'aug', 'sep', 'oct', 'nov', 'dec'), lower-case(substring(regex-group(2), 1, 3))), '00')'

Also see below xslt code for reference:
<xsl:analyze-string select="." regex="(\d+)\s([A-Za-z]+)\s(\d{{4}})\.">
                     <xsl:matching-substring>

                        <!--<xsl:variable name="MONTH">
                           <xsl:value-of
                              select="format-number(index-of(('jan', 'feb', 'mar', 'apr', 'may', 'jun', 'jul', 'aug', 'sep', 'oct', 'nov', 'dec'), lower-case(substring(regex-group(2), 1, 3))), '00')"
                           />
                        </xsl:variable>-->
                        <xsl:variable name="DAY">
                           <xsl:value-of select="format-number(number(regex-group(1)), '00')"/>
                        </xsl:variable>
                        <xsl:element name="date">
                           <xsl:if test="not($MONTH = 'NaN')">
                              <xsl:if test="$DAY &gt; 0 and $DAY &lt; 32">
                                 <xsl:attribute name="day">
                                    <xsl:value-of select="$DAY"/>
                                 </xsl:attribute>
                              </xsl:if>
                              <xsl:attribute name="month">
                                 <xsl:value-of select="$MONTH"/>
                              </xsl:attribute>
                           </xsl:if>
                           <xsl:attribute name="year" select="regex-group(3)"/>
                           <xsl:value-of
                              select="concat(regex-group(1), ' ', regex-group(2), ' ', regex-group(3), '.')"
                           />
                        </xsl:element>
                     </xsl:matching-substring>
                     <xsl:non-matching-substring>
                        <xsl:value-of select="."/>
                     </xsl:non-matching-substring>
                  </xsl:analyze-string>

Kindly please resolve this issue or provide module for transformation if you have.

Thanks

XSLT is implemented in libxslt, not in lxml.
