Re: Identifying place names in text...

Hi,

Tempore 15:56:22, die 07/21/2005 AD, hinc in xsl-list(_at_)lists(_dot_)mulberrytech(_dot_)com scripsit Karl Koch <TheRanger(_at_)gmx(_dot_)net>:

Can I use XSLT to search for place names in the title of all the books? I
would like to use a wordlist of geographical place names (which I already
have). This would contain coutry and city names. The stylesheet would match occurances of these words in the <title> XML element. The output here would be a list of all books which have references about locations in the title.

You can map references to the titles with a stylesheet like this:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
<xsl:output method="xml" indent="yes"/>

<xsl:param name="locations" select="document('locations.xml')/places/city"/>

<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>

<xsl:template match="title">
        <xsl:copy-of select="."/>
        <xsl:for-each select="$locations[contains(current(),.)]">
                <reference><xsl:value-of select="."/></reference>
        </xsl:for-each>
</xsl:template>

</xsl:stylesheet>

locations.xml would contain:
<places>
        <city>London</city>
        <city>Paris</city>
</places>

regards,
