Subject: Traversing XML Tree - Want to get next Element
Author: K J

Hi all,

I have some XSL that goes down the structure and when I get to a particular tag I want the variable Im declaring to hold just the next tag name. This is shown below:

<a>
<b>
<c/>
</b>
</a>

So what I want is to go down to <b> and then get the value of <c>. This could be different everytime so next time it could be <d/>.

Any suggestions would be appreciated,

Tony Lavinio

It's not really clear what you are asking for a real document.
When you say 'tag' do you mean 'element'?
It is best when thinking of XML not to think of a stream of tags,
but of the elements that comprise the start and end tags and their
content.

Assuming by 'next' you mean 'first child', for the following sample
file, this would get the name of the 'first child' of each second-level
element as the value of that element in the output.

Input:
<a><b><c/></b><b><d/></b></a>

XSLT:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<a>
<xsl:apply-templates select="a/*"/>
</a>
</xsl:template>
<xsl:template match="*">
<xsl:element name="{local-name(.)}">
<xsl:value-of select="local-name(*[1])"/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>

Output:
<?xml version='1.0' ?>
<a><b>c</b><b>d</b></a>

Apologies my question was prob confusing,

What I need to do is traverse down the tree and then at a specific point get the name of the next element...e.g:

<name>
<surname>
<Smith>
</Smith>
</surname>
</name>

I need to get the element name the item under <surname>, this could be <Fred> next time, I just need to be able to get the name of the element,

Thanks again,

Tony Lavinio

local-name(*[1]) will return the name of the first child element
of the current element.

The supplied example in the previous answer should help you.

If you want the next peer instead of the next child, you should
investigate the following-sibling:: axis.
