Re: [xsl] Problem with a key

The use= attribute is calculated relative to the node matched.

You are matching on title so you need to express use= as relative to the title element.

BTW, the use of text() may happen to work but it is a bad habit to get into. So very (very!) rarely have I ever needed to use text(). If you want the text value of an element, simply address the element.

I hope this helps.

I am trying to use a key to return the errata_section title elements, given the device_name element attached to the parent errata_section.

The structure is like the following:

<errata_section>
  <title>Bug title 1</title>

  <devices_impacted>
     <device_name>Mod1</device_name>
  </devices_impacted>
  <devices_impacted>
     <device_name>Mod45</device_name>
  </devices_impacted>
,
,
,
</errata_section>

<errata_section>
.
.
.
</errata_section>

As several devices maybe addressed in a given errata_section element, i was trying to write a key to pull out, for a given device, ALL the errata_section titles that impact this device name. (Ideally for inclusion into a table based on the device name.

I wrote the following thinking this might work:

<xsl:key name="bugtitlekey" match="errata_section/title" use="errata_section/devices_impacted/device_name" />
<xsl:template match="/">
<xsl:value-of select="key('bugtitlekey', 'Mod4')/text()"/>

</xsl:template>

I don't get any output when i try this. I thought my key def was ok. Do i need to go deeper per each errata_section element?
