Subject: merge contents of consecutive duplicate elements
Author: Ann Marie Rubin
Date: 18 Oct 2005 10:03 AM

Hello,

I have XML that can contain duplicate, consecutive elements with different contents, for example:

<info>
<para>text A </para>
<note>note A </note>
</info>
<info>
<para>text B</para>
<note>note B</note>
<para>text C</para>
</info>

How can I do the following in XSLT 1.0?

merge the contents of the duplicate elements into a single info element, for example:

<info>
<para>text A</para>
<note>note A</note>
<para>text B</para>
<note>note B</note>
<para>text C</para>
</info>

Thanks,

Ann Marie

If you do want to generate single element to replace group of elements with the same name (and concatinate content) you can use something like this :

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:key name="Key" match="/xml/*" use="local-name()"/>

<xsl:template match="/">
<xml>
<xsl:for-each select="/xml/*">
<xsl:if test="generate-id()= generate-id(key('Key',local-name())[1])">
<xsl:copy select=".">
<xsl:for-each select="key('Key',local-name())">
<xsl:value-of select="."/>
</xsl:for-each>
</xsl:copy>
</xsl:if>
</xsl:for-each>
</xml>
</xsl:template>
</xsl:stylesheet>

But from your example I can see that probably you do want to do different thing : just use single <info> as a root and collect all children of all <info> elements from original XML under this info. If this is tha case you can use following XSLT:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xml>
<info>
<xsl:for-each select="xml/info/*">
<xsl:copy-of select="."/>
</xsl:for-each>
</info>
</xml>
</xsl:template>
</xsl:stylesheet>

thanks for the suggestion, Yuriv.

Yes, I want to generate a single element to replace two consecutive info elements that are children of an overview element and have the same name (and concatinate content.) There will be no more than one pair of these info elements in each overview element. I don't want to generate a single element containing all duplicate elements.

For example, this code finds the info element that is a child of an overview element and whose next following sibling is also an info element.

<xsl:template match="overview/info[following-sibling::*[1][self::info]]" >

At this point, I'm stuck. How do I concatenate both elements?

thanks,

Ann Marie

Hi Ann,

Assuming your input looks like this

<?xml version="1.0"?>
<overview>
<info>
<para>text A</para>
<note>note A</note>
</info>
<info>
<para>text A</para>
<note>note A</note>
<para>text B</para>
<note>note B</note>
<para>text C</para>
</info>
</overview>

applying the following

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>

<xsl:template match="/">
<xsl:apply-templates select="overview"/>
</xsl:template>

<xsl:template match="overview">
<xsl:copy>
<info>
<xsl:apply-templates select="*"/>
</info>
</xsl:copy>
</xsl:template>

<xsl:template match="info">
<xsl:apply-templates select="*"/>
</xsl:template>

<xsl:template match="*">
<xsl:variable name="current" select="."/>
<xsl:if test="not(../following-sibling::info[1]/*[. = $current])">
<xsl:copy-of select="."/>
</xsl:if>
</xsl:template>

</xsl:stylesheet>

results in

<?xml version='1.0' ?>
<overview>
<info>
<para>text A</para>
<note>note A</note>
<para>text B</para>
<note>note B</note>
<para>text C</para>
</info>
</overview>

hope this helps

The info elements are still not merged. Can you see what the problem is? Note that I needed to add the <xsl:apply-templates select="@*|node()"/> statement in the match / template or I got no output at all.

Thanks,

If your task is to replace all <info> elements located under <overview> element with a single <info> element and concatinate children under this new <info> and you want to do this in cases a) and b) :

a) <overview>
<info/>
<other/>
<info/>
</overview>

and

b)
<overview>
<info/>
<info/>
<other/>
</overview>

then you can use this :

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>

<xsl:template match="/">
<xml>
<xsl:apply-templates select="descendant::overview"/>
</xml>
</xsl:template>

<xsl:template match="overview">
<info>
<xsl:for-each select="info/*">
<xsl:copy-of select="."/>
</xsl:for-each>
</info>
</xsl:template>

</xsl:stylesheet>

If you want to perform merge only in case b) extra check have to be added.

Hi Yuriv,

Thanks for your help. I hope you can give me some tips on how to do this.

How can I modify my stylesheet to handle this case:

Regards,

Ann Marie

input:

<concept>
<overview>
<info>
<para>A</para>
</info>
</overview>
<info>
<para>B</para>
</info>
</concept>

There are overview elements in other parts of the tree that don't want to change. I want to combine info element children of concept/overview with the info element that is the immediately following sibling of overview in a single info element.

desired output:

<concept>
<info>
<para>A</para>
<para>B</para>
</info>
</concept>

In case you were looking to just merge the duplicates under overview/info and leave the rest as it is, take a look to the attached solution

hope this helps

thanks Ivan.

I need to merge the duplicate info elements under overview children of concept but not other info elements. See my reply to Yuriv. I'm going to try out this stylesheet and see if I can modify it to merge the info child of concept/overview with overview's following sibling info node.

that's the problem I need to solve now.

If you have any suggestions, I would greatly appreciate it.

thanks much,

Ann Marie

Take a look at this example:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>

<xsl:template match="/">
<concept>
<info>
<xsl:apply-templates select="concept/overview/info/para | concept/info/para"/>
</info>
</concept>
</xsl:template>

<xsl:template match="para">
<xsl:copy-of select="."/>
</xsl:template>
</xsl:stylesheet>

We can modify Ivan template to handle this case too, so you'll get original tree with info elements merged, not just sample case. But let's make sure first that we understand requirements correctly.
If you will post complete input XML with all possible cases and desired output XML we will try to come up with stylesheet.

Regards,

Yuriy

Hello Yuriy,

Sorry for the delay. I am attaching the input xml and desired output xml. I only want to merge the contents of subconcept/overview/info and the following-sibling info element of subconcept/overview. There are overview/info elements that are children of other elements, such as, minitask, that should be left alone.

Let me know if you have any questions about the requirements.

Ann Marie

Hello Yuriy,

Sorry for the delay. I am attaching the input xml and desired output xml. I want to remove overview children of subconcept and merge the contents of subconcept/overview/info and the following-sibling info element of subconcept/overview. There are overview/info elements that are children of other elements, such as, minitask, that should be left alone.

For example, the following input:
<subconcept id="_8">
<title>concept</title>
<overview>
<info>
<para>para A</para>
</info>
</overview>
<info>
<para>para B</para>
</info>
</subconcept>

should be changed to:
<subconcept id="_8">
<title>subconcept</title>
<info>
<para>para 1</para>
<para>para 2</para>
</info>
</subconcept>
Let me know if you have any questions about the requirements.

You can change Ivan XSLT (published in this thread) :

change :

<xsl:template match="overview">

into :

<xsl:template match="subconcept/overview">

and you'll get following output:

2 <info> tags replaced with single <info>
all <info> children are merged (<para>)
and all this happens only if <overview> is direct child of <subconcept>

Hope this will help

Hi,

I ran Ivan's merge_duplicates.xsl with template match=subconcept/overview. The info elements are still not merged. Did I miss something?

Take a look how in :

<subconcept>
<title>subconcept</title>
<overview>
<info>
<para>overview paragraph A</para>
</info>
<info>
<para>overview paragraph B</para>
</info>
</overview>
<info>
<para>test</para>
</info>
</subconcept>

2 <overview> child <info> elements were replaced with one <info> element with merged children :

<subconcept>
<title>subconcept</title>
<overview>
<info>
<para>overview paragraph A</para>
<para>overview paragraph B</para>
</info>
</overview>

Ah. This stylesheet merges para A and B given this xml input:
<overview>
<info>
<para>para A</para>
</info>
<info>
<para>para B</para>
</info>

</overview>
<info>
<para>para C</para>
</info>

To get this xml output:
<info>
<para>para A</para>
<para>para B</para>
</info>
<info>
<para>para C</para>
</info>

But, I'm trying to remove the overview element and merge para A and para C in this xml input :

<overview>
<info>
<para>para A</para>
</info>

</overview>
<info>
<para>para C</para>
</info>

To get this xml output:
<info>
<para>para A</para>
<para>para C</para>

</info>

see my attached xml input.

thanks,

Ann Marie
