Hi Everyone,
I've merged two documents on a set of <view> nodes using the Meunchian method.
<view_doc>
<view name="view1">
<column file="dev" id="view1.NAME"></column>
<column file="dev" id="view1.DESCRIPTION"></column>
</view>
<view name="view2">
<column file="doc" id="view2.ID">text</column>
<column file="doc" id="view2.TIME_STAMP">text</column>
<column file="doc" id="view2.CUSTOM0">text</column>
<column file="dev" id="view2.CUSTOM1"></column>
</view>
<view name="view3">
<column file="doc" id="view3.ID">text</column>
<column file="doc" id="view3.TIME_STAMP">text</column>
<column file="doc" id="view3.CREATED_ON">text</column>
<column file="dev" id="view3.ID"></column>
<column file="dev" id="view3.TIME_STAMP"></column>
<column file="dev" id="view3.CREATED_ON"></column>
</view>
</view_doc>
Now I'm trying to identify the <column> nodes where duplicate @id
values exist. Where there are duplicates, I'd like to include the
nodes where the @file value is "doc." But the output should also
include the unique column nodes, all of which have a @file value of
"dev."
Desired output:
<?xml version="1.0" encoding="UTF-8"?>
<view_doc>
<view name="view1">
<column file="dev" id="view1.NAME"></column>
<column file="dev" id="view1.DESCRIPTION"></column>
</view>
<view name="view2">
<column file="doc" id="view2.ID">text</column>
<column file="doc" id="view2.TIME_STAMP">text</column>
<column file="doc" id="view2.CUSTOM0">text</column>
<column file="dev" id="view2.CUSTOM1"></column>
</view>
<view name="view3">
<column file="doc" id="view3.ID">text</column>
<column file="doc" id="view3.TIME_STAMP">text</column>
<column file="doc" id="view3.CREATED_ON">text</column>
</view>
</view_doc>
In the past few days, I've tried every bit of XSL logic I could find
online, including those in the archives of this list. Some have gotten
me closer than others. Here is my current XSL. It isn't the best
example. Unfortunately, I haven't saved every version Ive tried.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xalan="http://xml.apache.org/xalan"
exclude-result-prefixes="xalan">
<xsl:output indent="yes"/>
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="@*"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="view">
<xsl:copy>
<xsl:for-each select="column">
<xsl:choose>
<xsl:when
test="not(preceding-sibling::column[(_at_)id =
current()/@id] or following-sibling::column[(_at_)id = current()/@id])">
<xsl:apply-templates
select="self::node()[(_at_)file='dev']"/>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates
select="self::node()[(_at_)file='doc']"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
I'd appreciate any advice.
Thanks,
Mark
