Cheers, Wendell
First, I'd like to thank Ken Hollman for all the help he has given me. He has saved this list much wasted bandwidth in answering my questions.
Here is a problem I am having that I think may be a grouping problem. Imagine I have nested lists of items within a document, something like this:
<section name="first"> <nestlist name="level_1"> <item name="apple"/> <item name="orange"/> <item name="truck"/> <item name="foo"/> <nestlist name="level_2"> <item name="orange"/> <item name="bar"/> <item name="truck"/> <nestlist name="level_3"> <item name="orange"/> <item name="foo"/> <item name="fnord"/> <item name="truck"/> <nestlist name="level_4"> <item name="foobar"/> <item name="apple"/> <item name="bar"/> </nestlist> </nestlist> </nestlist> </nestlist> </section>
I would like to be able to select the first instance of every item in the above with a specific name attribute, without having prior knowledge of what that name might be. For example, I would like to be able to create a select statement that would process item elements along these lines:
- apple orange truck and foo in the level_1 nestlist - bar in the level_2 nestlist - fnord in level_3 - foobar in level_4
I have very large lists like this, and need to perform operations on the first occurance of a unique name.
I have been attempting it with something like:
<xsl:for-each select="section"> <xsl:variable name="sectname" select="$name"/> <xsl:for-each select="//nestlist/item"> <xsl:variable name="name" select="@name"/> <xsl:for-each select="(/section//nestlist/item[@name=$name])[1]"> <!--Do something here--> </xsl:for-each> +</xsl:for-each> </xsl:for-each>
But, it seems, this is not valid. How would I go about this?
