Matching templates causing problem

pushkar_joshi · August 20th, 2010, 10:01 AM

My xml code(example)

Code:

<orderprice>
  <orderstack>
    <order>
      <ord1>
        120
      </ord1>
      <ord2>
        130
      </ord2>
    </order>
  </orderstack>
  <orderamt>
    <order>
      <ordprice1>
        440
      </ordprice1>
      <ordprice2>
        450
      </ordprice2>
    </order>
  </orderamt>
</orderprice>

I have 2 templates as below.

Code:

<xsl:template match ="order/*">
 <!--something--!>
</xsl:template>

<xsl:template match ="ordprice1">
<!-- different rules than first template--!>
</xsl:template>

The problem is that when I use
<xsl:apply-templates select="order/*" />
it never invokes the 2nd template. Since the contents of order can keep changing, I need to use "order/*". How can I invoke 2nd template.

Simply apply the attribute priority="2" to the second template, so when it matches an element it has a greater priority than the other template.

The default priority is actually 0.5 I believe, so any number > 0.5 will work.

Further information: The rules for conflict resolution are a bit complicated, and are given here in the spec: http://www.w3.org/TR/xslt#conflict

Basically, "order/*" is more specific (and hence higher priority) than "orderprice1". "order/orderprice1" would be the same priority as "order/*" and should report an error (or if not then choose the last template in the stylesheet).

Giving the second template a high manual priority is the quickest way to make sure the correct template runs if it matches.

It did not give me error but chose the last template. Assigning priority worked.

Thanks for the link and info.
