xslt copy of attribute from wrong element - xslt

Question

I'm using this template:
<xsl:transform version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xpath-default-namespace="http://www.liquibase.org/xml/ns/dbchangelog"
xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
xmlns:uuid="http://uuid.util.java"
exclude-result-prefixes="uuid">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="changeSet[createTable]">
<xsl:copy>
<xsl:copy-of select="#*"/>
<xsl:apply-templates select="createTable"/>
<xsl:copy-of select="*[not(self::createTable)]"/>
</xsl:copy>
<xsl:if test="createTable/#remarks">
<xsl:element name="changeSet">
<xsl:attribute name="id" select="uuid:new-uuid()"/>
<xsl:attribute name="author">system</xsl:attribute>
<xsl:element name="setTableRemarks">
<xsl:copy-of select="createTable//(#tableName,#remarks)" />
</xsl:element>
<xsl:for-each select="createTable/column[#remarks]">
<xsl:element name="setColumnRemarks">
<xsl:copy-of select="../#tableName" />
<xsl:attribute name="columnName" select="#name"/>
<xsl:copy-of select="#remarks"/>
</xsl:element>
</xsl:for-each>
</xsl:element>
</xsl:if>
</xsl:template>
<xsl:template match="createTable/#remarks"/>
<xsl:template match="createTable/column/#remarks"/>
</xsl:transform>
to transform xml like this:
<?xml version="1.0" encoding="UTF-8"?>
<databaseChangeLog xmlns="http://www.liquibase.org/xml/ns/dbchangelog" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.6.xsd">
<changeSet author="system (generated)" id="1538720867962-1">
<createTable remarks="Journal event detail attribute mapping" tableName="AS_JOURNALEVENTDETAILATTRMAP">
<column name="JOURNALEVENTTYPEID" remarks="Journal event type identifier" type="NUMBER(9, 0)">
<constraints primaryKey="true" primaryKeyName="PK$AS_JOURNALEVENTDETATTRMAP"/>
</column>
<column name="JOURNALEVENTDETAILATTRID" remarks="Journal event detail attribute identifier" type="NUMBER(9, 0)">
<constraints primaryKey="true" primaryKeyName="PK$AS_JOURNALEVENTDETATTRMAP"/>
</column>
<column name="LISTORDER" remarks="Order in list" type="NUMBER(9, 0)">
<constraints nullable="false"/>
</column>
</createTable>
</changeSet>
</databaseChangeLog>
I expect that result will be:
<databaseChangeLog xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.6.xsd">
<changeSet author="system (generated)" id="1538720867962-1">

<constraints primaryKey="true" primaryKeyName="PK$AS_JOURNALEVENTDETATTRMAP"/>
</column>
<column name="JOURNALEVENTDETAILATTRID" type="NUMBER(9, 0)">
<constraints primaryKey="true" primaryKeyName="PK$AS_JOURNALEVENTDETATTRMAP"/>
</column>
<column name="LISTORDER" type="NUMBER(9, 0)">
<constraints nullable="false"/>
</column>
</createTable>
</changeSet>
<changeSet id="c85f187d-f917-4948-8c48-7b1a132dd79e" author="system">
<setTableRemarks remarks="Journal event detail attribute mapping" tableName="AS_JOURNALEVENTDETAILATTRMAP"/>
<setColumnRemarks tableName="AS_JOURNALEVENTDETAILATTRMAP"
columnName="JOURNALEVENTTYPEID"
remarks="Journal event type identifier"/>
<setColumnRemarks tableName="AS_JOURNALEVENTDETAILATTRMAP"
columnName="JOURNALEVENTDETAILATTRID"
remarks="Journal event detail attribute identifier"/>
<setColumnRemarks tableName="AS_JOURNALEVENTDETAILATTRMAP"
columnName="LISTORDER"
remarks="Order in list"/>
</changeSet>
</databaseChangeLog>
but instead of that I get this:
<databaseChangeLog xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.6.xsd">
<changeSet author="system (generated)" id="1538720867962-1">
<createTable tableName="AS_JOURNALEVENTDETAILATTRMAP">
<column name="JOURNALEVENTTYPEID" type="NUMBER(9, 0)">
<constraints primaryKey="true" primaryKeyName="PK$AS_JOURNALEVENTDETATTRMAP"/>
</column>
<column name="JOURNALEVENTDETAILATTRID" type="NUMBER(9, 0)">
<constraints primaryKey="true" primaryKeyName="PK$AS_JOURNALEVENTDETATTRMAP"/>
</column>
<column name="LISTORDER" type="NUMBER(9, 0)">
<constraints nullable="false"/>
</column>
</createTable>
</changeSet>
<changeSet id="c85f187d-f917-4948-8c48-7b1a132dd79e" author="system">
<setTableRemarks remarks="Order in list" tableName="AS_JOURNALEVENTDETAILATTRMAP"/>
<setColumnRemarks tableName="AS_JOURNALEVENTDETAILATTRMAP"
columnName="JOURNALEVENTTYPEID"
remarks="Journal event type identifier"/>
<setColumnRemarks tableName="AS_JOURNALEVENTDETAILATTRMAP"
columnName="JOURNALEVENTDETAILATTRID"
remarks="Journal event detail attribute identifier"/>
<setColumnRemarks tableName="AS_JOURNALEVENTDETAILATTRMAP"
columnName="LISTORDER"
remarks="Order in list"/>
</changeSet>
</databaseChangeLog>
note: the problem is in element setTableRemarks and attribute remarks. It's coppied from another element not from createTable as I guess it should be. Is something in my template wrong or is there another problem?
saxon library used for this is 9.8.0-14 I also tried with 9.9.0-1 but nothing has changed.

Answer 1

Instead of doing this...
<xsl:copy-of select="createTable//(#tableName,#remarks)" />
Do this...
<xsl:copy-of select="createTable/(#tableName,#remarks)" />
Using // is shorthand for /descendant-or-self::node()/ and so is going to search all descendant nodes of createTable, not just the node itself. As this will select multiple attributes with the same name, only the last one will be copied (as adding an attribute to a node where an existing one with the same name already exists should replace it).
