Specific order, need order from XSL not from input xml format

pAperBlaze · September 10th, 2013, 08:43 AM

I am facing a problem with same name nodes at the same level and specific order. My order depends on the value of their nodes. My output should be a txt file. My XML looks like:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<header>
             <B>
		<element>
			<value>10</value>
			<value>test</value>
		</element>
	</B>

	<A>
		<element>
			<value>100</value>
			<value>message</value>
		</element>
	</A>
             <B>
		<element>
			<value>20</value>
			<value>phase</value>
		</element>
	</B>

	<A>
		<element>
			<value>101</value>
			<value>type</value>
		</element>
	</A>
             <B>
		<element>
			<value>20</value>
			<value>phase</value>
		</element>
	</B>

	<A>
		<element>
			<value>101</value>
			<value>type</value>
		</element>
	</A>
             
</header>

My txt output should look like that.

typephase
typephase

and so on.

My XSL looks like that

Code:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
	version="1.0">
	<xsl:output method="text" indent="yes" />
	<xsl:template match="header/child::node()">
			
			<xsl:if test="name(.) = 'A' and element/value='101'">
				<xsl:value-of select="element/value[position()=2]" />
			</xsl:if>
			<xsl:if test="name(.) = 'B' and element/value='20'">
				<xsl:value-of select="element/value[position()=2]" />
			</xsl:if>
			<xsl:text>&#xa;</xsl:text>		
	</xsl:template>
	
	<xsl:template match="/">
		<xsl:apply-templates select="header"></xsl:apply-templates>
	</xsl:template>
</xsl:stylesheet>

The result with this XSL is:

phasetype
phasetype

xsl:sort descending doesn`t help me, because the original input XML has much more nodes. I need the order from the XSL not from the input XML document. Does anyone know, how to solve this?

Something like the following.

Code:

<xsl:template match="header/*">
   <xsl:sort select="element/value[1]" datatype="number"/>
   ...
</xsl:template>

Please try describing in English some kind of specification of your transformation, e.g. the following is consistent with your results, but I've no idea if this is what you had in mind:

First process all the elements with value 101, processing the A elements first, then the B elements.

Then process all the elements with value 20, processing the A elements first, then the B elements.

The problem with both solutions are that the result would be then

type type phase phase

if i understand you correctly

but I need

type phase
type phase
type phase
<A> <B>

and so on.

normally the order output of a xsl transformation depends on the order in the xml input but i want to define the order in the xsl stylesheet.

You've described what you want the output to look like, but you need to describe, really well, how you work out that ordering.

How do you know that the first B comes after the first A, and not after the second A? Are the elements always in pairs, and you want to reverse the order (so B -> A, becomes A -> B)? Or is there some other logic in your ordering that you could make clear to us?

You say you want to define the order in the XSL stylesheet, but we really don't know what that ordering is.
