Question

XPath Query

Asked by: FirePits

I am using the following xsl to transform my xml document:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml"
  version="1.0"
  encoding="iso-8859-1"
  indent="yes" />

  <xsl:template match="/">
    <xsl:element name="library">
      <xsl:attribute name="value">
        <xsl:value-of select="'My iTunes Library'" />
      </xsl:attribute>
      <xsl:apply-templates select="plist/dict/dict/dict"/>
    </xsl:element>
  </xsl:template>

  <xsl:template match="plist/dict/dict/dict">
    <xsl:element name="track">
      <xsl:attribute name="value">
        <xsl:value-of select="key[.='Name']/following-sibling::node()[1]"/>
      </xsl:attribute>
      <xsl:call-template name="artist" />
      <xsl:call-template name="album" />
    </xsl:element>
  </xsl:template>

  <xsl:template name="artist">
    <xsl:element name="artist">
      <xsl:attribute name="value">
        <xsl:value-of select="key[.='Artist']/following-sibling::node()[1]"/>
      </xsl:attribute>
    </xsl:element>
  </xsl:template>

  <xsl:template name="album">
    <xsl:element name="album">
      <xsl:attribute name="value">
        <xsl:value-of select="key[.='Album']/following-sibling::node()[1]"/>
      </xsl:attribute>
    </xsl:element>
  </xsl:template>
 
</xsl:stylesheet>


When using the transformed XML as a datasource I would like to only return 'track' elements that have the sub-element 'artist' attribute equal to a string. For example, I think it might go something like this:  "library/track/artist[@value='ArtistName']"   I have a very general knowledge of XPath, but I just can't seem to get this working. Thanks in advance!

If "artist" is an attribute of "track" then it would be:

    library/track[@artist='ArtistName']

 

by: enachemcPosted on 2006-07-25 at 09:53:34ID: 17177422

Could you give us an example XML and the expected output ?

//track[./*[@artits='some artist]]

 

by: FirePitsPosted on 2006-07-26 at 08:23:29ID: 17185140

So, the XML would look something like this:

<library>
<track value="Track Name">
<artist value="ArtistName />
<album value="AlbumName" />
</track>
</ibrary>

I want to return the track elements that have the artist attribute equal to a specified string.

 

by: carl_tawnPosted on 2006-07-26 at 08:35:58ID: 17185283

In that case:

    library/track[artist[@value='SomeValue']]

 

by: enachemcPosted on 2006-07-26 at 08:38:54ID: 17185314

//library/track[count(artist[@value='SomeValue']) > 0]
