Conditionally selecting following element

seb · February 2nd, 2012, 09:27 AM

I have a snippet of xml:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<sect>
	<Link>3</Link>
	<Link>4</Link>
	<Link>5</Link>
	<footnote>3 this is the footnote text</footnote>
	<footnote>4 this is the footnote text</footnote>
	<footnote>5 this is the footnote text</footnote>
</sect>

I want to transform it with xslt 1.0 to:

Code:

<span class="link" title="3 this is the footnote text">[3]</span>
<span class="link" title="4 this is the footnote text">[4]</span>
<span class="link" title="5 this is the footnote text">[5]</span>

What I have tried so far is:

Code:

<xsl:template match="Link">
    <span class="link">	
		    <xsl:attribute name="title"><xsl:value-of select="following::footnote[1]"/></xsl:attribute>
		    [<xsl:value-of select="."/>]
    </span>	
</xsl:template>

This returns

Code:

<span class="link" title="3 this is the footnote text">[3]</span>
<span class="link" title="3 this is the footnote text">[4]</span>
<span class="link" title="3 this is the footnote text">[5]</span>

I am not sure how to do a test on the following footnote in order to get past the first one and check the following ones.

If the task is really as you describe it, then the output depends only on the footnote elements and not on the Link elements. So you could just ignore the Link elements and process the footnotes.

That isn't the case... The links appear within paragraph text and I want the spans to appear in those appropriate positions.

Such as:

This is advice about swimming [1] off the Dorset Coast. Next sentence [4] etc...

OK, so the input isn't what you showed us, and we're expected to guess what it's really like.

Isn't it possible to use some structured markup to identify the footnotes, for example

Code:

<footnote nr="3">This is the third footnote</footnote>

That would make things much easier, especially if you are using XSLT 1.0.

Apologies, I hadn't appreciated that the xml would be interpreted that way:

<code>
<sect>
It is widely accepted that the worldâs climate asdfsadfsdf sdf asdf sdf afd a 
Over the past century, the Earth has asdf sdfsadf asdf sdfadsf
<Link>3</Link>
. adsf safd sadf sadfsadf sadf sadf sad fsad
<Link>4</Link>
.asd asd sadf sadfsadf sadf sadf sadf sadf asdf sadfsad d 
blah blah blah 
<footnote>3 Global temperature trends 1911-2010 asdf sadfsadf sadfsad fasdf</footnote>
<footnote>4 Global temperature trends 1975-2010 were: Hasdf sad fsafd sa </footnote>
</sect>
</code>

I would like the links to appear where they are in the paragraphs. I won't be displaying the footnotes at the foot of the html displayed page but will have a hover over the links that will display the footnotes.

Define a key

Code:

<xsl:key name="n" match="footnote" use="substring-before(., ' ')"/>

and use it like this:

Code:

<xsl:template match="Link">
...
<xsl:value-of select="key('n', .)"/>

Thanks Michael, that's perfect.
