Problem with selective counting

still_learning · March 22nd, 2007, 05:29 PM

Here is a sample of my XML code:

<map>

<topic>

<title>Main Title - I want to count this</title>

<body>...</body>

    <topic>

    <title>Sub title - I don't want to count this</title>

    <body>...</body>

    </topic>

    <topic>

    <title>Sub title - I don't want to count this</title>

    <body>...</body>

    </topic>

</topic>

<topic>

<title>Main Title - I want to count this</title>

<body>...</body>

    <topic>

    <title>Sub title - I don't want to count this</title>

    <body>...</body>

    </topic>

</topic>

</map>

My XSL uses the following code to match against the main titles:

<xsl:template match="*[contains(@class,' topic/topic ')]/*[contains(@class,' topic/title ')]" priority="2">

<xsl:call-template name="get-title"/>

</xsl:template>

The match works fine - only the main titles are picked up and processed differently than the others. But I can't seem to apply the same logic to add numbering - every title is counted, not just the main ones.

Here's what I've tried so far:

1. <xsl:number count="*/*[contains(@class,' topic/topic ')]/*[contains(@class,' topic/title ')]" level="any"/>

2. <xsl:number count="*/*[contains(@class,' topic/title ')]" level="any"/>

3. <xsl:number format="1. " level="any" count="topic|title"/>

Is there a way I could add a condition so that only the titles of topics who are direct descendants of map are counted, not the titles of topics who are descendants of other topics?

I can't really follow your logic. You seem to be numbering elements based on the presence of an @class attribute, but in your XML source none of the elements has a @class attribute.

If it's true that

match="*[contains(@class,' topic/topic ')]/*[contains(@class,' topic/title ')]"

matches all the elements you want to number, and only the ones you want to number, then you should be able to use

<xsl:number count=" match="*[contains(@class,' topic/topic ')]/*[contains(@class,' topic/title ')]" level="any"/>
