RE: [xsl] Need to output an opening or closing tag by itself

---

---

I have somewhat similar issue, wherein I had empty element <email/>, which I
want to be keep as empty in the resulting xml. Here it looks like:


Input:
======
<email url="xxx@xxxxxxx"/>


Output requires
================
<email url="xxx@xxxxxxx"/>
<fnt>
*Email: xxx@xxxxxxx
</fnt>


Stylesheet
======================
<xsl:template match="email[@url]">
		<xsl:copy>
			<xsl:copy-of select="@*"/>
			<fnt>
					<xsl:choose>
						<xsl:when
test="count(ancestor::meta/author)!=1">
	
<xsl:text>*Corresponding author: Email: </xsl:text>
						</xsl:when>
						<xsl:otherwise>
							<xsl:text>*Email:
</xsl:text>
						</xsl:otherwise>
					</xsl:choose>
					<xsl:value-of select="./@url"/>
				</fnt>
		</xsl:copy>
</xsl:template>


But using the above, I am getting the following, which is not the way I
wanted:

What I get
===========
<email url="xxx@xxxxxxx">
<fnt>
*Email: xxx@xxxxxxx
</fnt>
</email>


I am using few other scripting languages after XML transformations, so I've
taken care of it their, but I know its not the best way of handling the XML
inputs.


Best,

The output of a transformation is a tree of nodes. It is not lexical XML
containing angle-bracket tags - those are produced from the result tree by
the serializer. Creating a node on the result tree is an atomic operation,
you can't create half a node.

The problem you are tackling is called positional grouping, In XSLT 2.0 you
can often tackle it using <xsl:for-each-group>. In 1.0 an appropriate
technique is often sibling recursion, where you process a sequence of
siblings one-by-one in a recursive template. You should be able to find
these techniques using a google search.
