Hello!
I need to search a word and it's context into an xml. For example
<line>hello world, my name is farhad and i'm having trouble with xslt</line>
looking for 'and', context of 3 words:
<line>hello world, my <span class="context">name is farhad <span class="word">and</span> i'm having</span> trouble with xslt</line>
How can i do? I wrote some xslt to find the word, but i can't go back 3 words to set span.
This is my xslt:
<xsl:variable name="delimiters">[,.;!?\s"()]+</xsl:variable>
<xsl:template match="/">
<xsl:apply-templates select="//line"/>
</xsl:template>
<xsl:template match="line">
<line>
<xsl:for-each select="tokenize(.,'\s')">
<xsl:choose>
<!-- se l'ultimo carattere è di punteggiatura, prendo la sottostringa senza la punteggiatura -->
<xsl:when test="compare(replace(.,$delimiters,'$1'),'red') = 0">
<span class="word">
<xsl:value-of select="."/>
</span>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="."/>
<xsl:choose>
<xsl:when test="position()=last()">
<xsl:text></xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:text> </xsl:text>
</xsl:otherwise>
</xsl:choose>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</line><xsl:text>
</xsl:text>
</xsl:template>
This is an example xml: http://pastebin.com/eAVM9CDQ .
I have to search for context also on preceding tags, for example:
<line>hello world,</line>
<line>my name</line>
<line>is farhad </line>
<line>and i'm having</line>
<line>trouble with xslt</line>
so, looking for 'and', context of 3 words:
<line>hello world,</line>
<line>my <span class="context">name</line>
<line>is farhad </line>
<line><span class="word">and</span> i'm having</span></line>
<line>trouble with xslt</line>
with problems of overlapping, but now it's not a problem (i think i know how manage it). How can i search a word and its context?
Thank you very much.
