Still XSL Problems

[Buchleitner Martin]

Hi!

I got another problem parsing my XML document:

<document>
<paragraph>
<style val=listing/>
<text>listing #1 text</text>
</paragraph>
<paragraph>
<style val=listing/>
<text>listing #1 text</text>
</paragraph>
<paragraph>
<style>text</style>
<text>some text between 2 listings</text>
</paragraph>
<paragraph>
<style val=listing/>
<text>listing #2 text</text>
</paragraph>
<paragraph>
<style val=listing/>
<text>listing #2 text</text>
</paragraph>
<paragraph>
<style val=listing/>
<text>listing #2 text</text>
</paragraph>
</document>

The output should look like:

<parsed>
<list>
<item>listing #1 text</item>
<item>listing #1 text</item>
<list>
<text>some text between 2 listings</text>
<list>
<item>listing #2 text</item>
<item>listing #2 text</item>
<item>listing #2 text</item>
<list>
</parsed>


My idea to get this result was:

<xsl:template match="text">
<xsl:value-of select="."/>
</xsl:template>

<xsl:template match="paragaph">
<xsl:if text="style[@val='listing'>
<list>
<item><xsl:apply-templates select="text"></item>

<xsl:for-each
select="following-sibling:aragraph/style[@val='listing']">
<item><xsl:apply-templates select="text"></item>
</xsl:for-each>
</list>
</xsl:if>
</xsl:template>
<xsl:template match="document">
<xsl:apply-templates select="paragraph"/>
</xsl:template>


But i was wrong - i get a document like:

<parsed>
<list>
<item>listing #1 text</item>
<item>listing #1 text</item>
<list>
<list>
<item>listing #1 text</item>
<list>
<text>some text between 2 listings</text>
<list>
<item>listing #2 text</item>
<item>listing #2 text</item>
<item>listing #2 text</item>
<list>
<list>
<item>listing #2 text</item>
<item>listing #2 text</item>
<list>
<list>
<item>listing #2 text</item>
</list>
</parsed>



How may i change my XSL to remove the repeated entries?
Can i modify the position in the paragraph-template?
Any ideas?

Hi Martin,

At the moment your XML is not well-formed... <style val=listing/> is not
well-formed because the attribute value is not enclosed in quotes. As this
is inconsistent with <style>text</style> part perhaps your XML looks more
like...

== XML =================================================
<document>
<paragraph>
<style>listing</style>
<text>listing #1 text</text>
</paragraph>
<paragraph>
<style>listing</style>
<text>listing #1 text</text>
</paragraph>
<paragraph>
<style>text</style>
<text>some text between 2 listings</text>
</paragraph>
<paragraph>
<style>listing</style>
<text>listing #2 text</text>
</paragraph>
<paragraph>
<style>listing</style>
<text>listing #2 text</text>
</paragraph>
<paragraph>
<style>listing</style>
<text>listing #2 text</text>
</paragraph>
</document>
== end of XML ==========================================

You are really needing to 'group' the <paragraph> elements by when the
<style> value changes. In which case something like...

== XSL1 ================================================
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xslutput method="xml" indent="yes"/>
<xsl:key name="kNonEqFollow" match="paragraph"
use="generate-id(following-sibling:aragraph[style != current()/style])"/>
<xsl:template match="document">
<parsed>
<xsl:apply-templates select="paragraph[not(preceding-sibling:aragraph)
or style != preceding-sibling:aragraph[1]/style]"/>
</parsed>
</xsl:template>

<xsl:template match="paragraph[style = 'listing']">
<!-- find the first following with a different <style> -->
<xsl:variable name="non-eq"
select="generate-id(following-sibling:aragraph[style !=
current()/style])"/>
<list>
<xsl:for-each select=". | key('kNonEqFollow',$non-eq)">
<item>
<xsl:value-of select="text"/>
</item>
</xsl:for-each>
</list>
</xsl:template>

<xsl:template match="paragraph[style = 'text']">
<!-- find the first following with a different <style> -->
<xsl:variable name="non-eq"
select="generate-id(following-sibling:aragraph[style !=
current()/style])"/>
<xsl:copy-of select="(. | key('kNonEqFollow',$non-eq))/text"/>
</xsl:template>

</xsl:stylesheet>
== end of XSL1 =========================================

However, if you are using MSXML 3.0 or MSXML 4.0 (pre SP2) then that
stylesheet will not work correctly due to a bug with current() in keys. An
alternative would be...

== XSL2 ================================================
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xslutput method="xml" indent="yes"/>
<xsl:template match="document">
<parsed>
<xsl:apply-templates select="paragraph[not(preceding-sibling:aragraph)
or style != preceding-sibling:aragraph[1]/style]"/>
</parsed>
</xsl:template>

<xsl:template match="paragraph[style = 'listing']">
<!-- find how many non-equal items follow this one -->
<xsl:variable name="count-non-eq"
select="count(following-sibling:aragraph[style != current()/style])"/>
<list>
<xsl:for-each select=". | following-sibling:aragraph[style =
current()/style and count(following-sibling:aragraph[style !=
current()/style]) = $count-non-eq]">
<item>
<xsl:value-of select="text"/>
</item>
</xsl:for-each>
</list>
</xsl:template>

<xsl:template match="paragraph[style = 'text']">
<!-- find how many non-equal items follow this one -->
<xsl:variable name="count-non-eq"
select="count(following-sibling:aragraph[style != current()/style])"/>
<xsl:copy-of select="(. | following-sibling:aragraph[style =
current()/style and count(following-sibling:aragraph[style !=
current()/style]) = $count-non-eq])/text"/>
</xsl:template>

</xsl:stylesheet>
== end of XSL2 =========================================

Hi!

You are really needing to 'group' the <paragraph> elements by when the
<style> value changes. In which case something like...

Well your xsl's work with the data i published, but when i try to
rewrite it to use it with my data, it does not work because i do not
know the xsl:key statement enough to get it running - or better : i do
not know how to write the use - parameter to get it working ...

== XSL1 ================================================ *snipped*
== end of XSL1 =========================================

Here i get this output:
======================================================
<parsed>listing #1 text<text>listing #1 text</text>
<text>some text between 2 listings</text>listing #2
text</parsed>
======================================================

Is this correct??

However, if you are using MSXML 3.0 or MSXML 4.0 (pre SP2) then that
stylesheet will not work correctly due to a bug with current() in keys. An
alternative would be...

I have to work with MSXML

== XSL2 ================================================ *snipped*
== end of XSL2 =========================================

Here i get a different looking output:
======================================================
<parsed>listing #1 text<text>some text between 2

Hope this helps

I think it shows me that i have to use the xsl:key and key() functions
to get a matching solution with the existing schema.



Thanks Martin

Hi Martin,

Is this correct??

How would I know??

Well your xsl's work with the data i published, but when i try to
rewrite it to use it with my data, it does not work because i do not
know the xsl:key statement enough to get it running - or better : i do
not know how to write the use - parameter to get it working ...
...

Please, if the stylesheets don't work with your actual XML then surely the
logical thing to do would be to show that actual XML?

I think it shows me that i have to use the xsl:key and key() functions
to get a matching solution with the existing schema.

No, not really, keys have nothing to do with schemas. XSLT 1.0 knows
nothing of schemas at all (input or output) - if you want the output to
validate against a given schema then that is down to the design of the
stylesheet to produce the right output... whatever that might be.

Cheers
Marrow

Ok i could do this

Here a part of my actual XML:
( This inherits everything which should be matched ... )

The <body> could inherit tags of <article> or <paragraph>.

Hi out there!

== XSL1 ================================================
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"

<xslutput method="xml" indent="yes"/>

However, if you are using MSXML 3.0 or MSXML 4.0 (pre SP2) then that
stylesheet will not work correctly due to a bug with current() in keys. An
alternative would be...

I am using Xalan-j so it should be ok or?

I adapted now this XSL1 to my needings:

the corresponding XML is

</group>

=========end of Output=======================================

But i want an output like the following:

<absatz>2 a text within a paragraph</absatz>
<list>
<item>2 listing item #1</item>
<item>2 listing item #2</item>
</list>
</group>
</parsed>
==========================================================


How can i rewrite my matching key to work only with the paragraph tags
within the bording - element??


TIA, Martin
