+ <para>
+ The &dom; filter allows indexing of both binary &marc; records
+ and &marcxml; records, depending on it's configuration.
+ A typical &marcxml; record might look like this:
+ <screen>
+ <![CDATA[
+ <record xmlns="http://www.loc.gov/MARC21/slim">
+ <rank>42</rank>
+ <leader>00366nam 22001698a 4500</leader>
+ <controlfield tag="001"> 11224466 </controlfield>
+ <controlfield tag="003">DLC </controlfield>
+ <controlfield tag="005">00000000000000.0 </controlfield>
+ <controlfield tag="008">910710c19910701nju 00010 eng </controlfield>
+ <datafield tag="010" ind1=" " ind2=" ">
+ <subfield code="a"> 11224466 </subfield>

+ It is easily possible to make string manipulation in the &dom;
+ filter. For example, if you want to drop some leading articles
+ in the indexing of sort fields, you might want to pick out the
+ &marcxml; indicator attributes to chop of leading substrings. If
+ the above &xml; example would have an indicator
+ <literal>ind2="8"</literal> in the title field
+ <literal>245</literal>, i.e.
+ <screen>
+ <![CDATA[
+ <datafield tag="245" ind1="1" ind2="8">
+ <subfield code="a">How to program a computer</subfield>
+ </datafield>
+ ]]>
+ </screen>
+ one could write a template taking into account this information
+ to chop the first <literal>8</literal> characters from the
+ sorting index <literal>title:s</literal> like this:
+ <screen>
+ <![CDATA[
+ <xsl:template match="m:datafield[@tag='245']">
+ <xsl:variable name="chop">
+ <xsl:choose>
+ <xsl:when test="not(number(@ind2))">0</xsl:when>
+ <xsl:otherwise><xsl:value-of select="number(@ind2)"/></xsl:otherwise>
+ </xsl:choose>
+ </xsl:variable>
+
+ <z:index name="title:w title:p any:w">
+ <xsl:value-of select="m:subfield[@code='a']"/>
+ </z:index>
+
+ <z:index name="title:s">
+ <xsl:value-of select="substring(m:subfield[@code='a'], $chop)"/>
+ </z:index>
+
+ </xsl:template>
+ ]]>
+ </screen>
+ The output of the above &marcxml; and &xslt; excerpt would then be:
+ <screen>
+ <![CDATA[
+ <z:index name="title:w title:p any:w">How to program a computer</z:index>
+ <z:index name="title:s">program a computer</z:index>
+ ]]>
+ </screen>
+ and the record would be sorted in the title index under 'P', not 'H'.
