xslt concat value of array - xslt

I'd like to apply template in which specified element contains value of array prefixed with some constant.
<xsl:variable name="coreTables"
select="('TAB1', 'TAB2')" />
<xsl:template match="node()[not(self::*)]">
<xsl:copy>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="*">
<xsl:element name="{local-name()}">
<xsl:apply-templates select="node()|#*"/>
</xsl:element>
</xsl:template>
<xsl:template match="#*">
<xsl:attribute name="{local-name()}">
<xsl:value-of select="."/>
</xsl:attribute>
</xsl:template>
<xsl:template match="databaseChangeLog">
<xsl:comment> CORE TABLES </xsl:comment>
<xsl:apply-templates select="changeSet[createTable/#tableName=$coreTables]"/>
<xsl:comment> CORE SEQUENCES </xsl:comment>
<xsl:apply-templates select="changeSet[createSequence/#sequenceName='SEQ_'[$coreTables]]"/>
</xsl:template>
this is sample xml:
<?xml version="1.1" encoding="UTF-8" standalone="no"?>
<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
http://www.liquibase.org/xml/ns/dbchangelog">
<changeSet id="1" author="a">
<createTable tableName="TAB1">
<column></column>
</createTable>
</changeSet>
<changeSet id="1-1" author="a">
<createSequence sequenceName="SEQ_TAB1" />
</changeSet>
<changeSet id="4" author="A">
<createTable tableName="TAB4">
<column></column>
</createTable>
</changeSet>
</databaseChangeLog>
So with with last apply-templates I'd like to match all nodes of createSequence where attribute sequenceName is SEQ_+value of some coreTables. But I don't know how to write this select or if it's even possible like this.
I'm using xslt 2 and saxon 9.8he.

There a number of ways you could do this. Here's a couple...
<xsl:apply-templates
select="changeSet[createSequence/#sequenceName = (for $i in $coreTables return concat('SEQ_', $i))]"/>
<xsl:apply-templates
select="changeSet[createSequence[starts-with(#sequenceName, 'SEQ_') and substring-after(#sequenceName, 'SEQ_') = $coreTables]]"/>

How to improve/refactor this xslt?

Given the following xml :
<tree>
<val>0</val>
<tree>
<val>1</val>
<tree>
<val>3</val>
</tree>
<tree>
<val>4</val>
</tree>
</tree>
<tree>
<val>2</val>
<tree>
<val>5</val>
</tree>
<tree>
<val>6</val>
</tree>
</tree>
</tree>
I need to transform it into this xml:
<root>0
<frst>1
<leaf>3</leaf>
<leaf>4</leaf>
</frst>
<second>2
<leaf>5</leaf>
<leaf>6</leaf>
</second>
</root>
This is my attempt that gives the same result, I recently started learning XSLT i'm not sure what other option I have, can this be improved or done in another way ?
Thank you for your help
This is my attempt :
<?xml version='1.0' encoding='utf-8'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" encoding="UTF-8"/>
<xsl:template match="/tree">
<root>
<xsl:apply-templates />
</root>
</xsl:template>
<xsl:template match="val">
<xsl:value-of select="."/>
</xsl:template>
<xsl:template match="tree">
<xsl:choose>
<!-- IF HAS CHILDREN -->
<xsl:when test="child::tree">
<xsl:if test="(count(preceding-sibling::tree)+1) = 1">
<frst>
<xsl:apply-templates/>
</frst>
</xsl:if>
<xsl:if test="(count(preceding-sibling::tree)+1) = 2">
<second>
<xsl:apply-templates/>
</second>
</xsl:if>
</xsl:when>
<!-- ELSE IS A LEAF -->
<xsl:otherwise>
<leaf>
<xsl:apply-templates/>
</leaf>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
test test
I would think the conditions can be written in match patterns:
<xsl:template match="tree[tree][1]">
<frst>
<xsl:apply-templates/>
</frst>
</xsl:template>
<xsl:template match="tree[tree][2]">
<second>
<xsl:apply-templates/>
</second>
</xsl:template>
<xsl:template match="tree[not(tree)]">
<leaf>
<xsl:apply-templates/>
</leaf>
</xsl:template>
although I guess your current code doesn't process the third/fourth/fifth.. tree children so an additional <xsl:template match="tree[tree][position() > 2]"/> might be necessary.

xslt copy attribute from external document

I've following xml
<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="c529c6ea-45c2-4ec2-8c9d-7bc935434d21" author="system">
<setTableRemarks remarks="this is wrong"
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>
and the exact same document with name fixedremarks.xml but there is little change <setTableRemarks remarks="this is ok" tableName="AS_JOURNALEVENTDETAILATTRMAP"/>
with following template I'm trying to fix attribute remarks inside setTableRemarks but without success - I don't know how to properly copy that attribute from external xml.
<xsl:transform version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xpath-default-namespace="http://www.liquibase.org/xml/ns/dbchangelog"

<xsl:variable name="originalChangeLog" select="document('/tmp/fixedremarks.xml')"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:key name="remarkTableName" match="setTableRemarks" use="#tableName"/>
<xsl:template match="changeSet[setTableRemarks]">
<xsl:variable name="currentRemarkTable" select="setTableRemarks/#tableName"/>
<xsl:comment select="$currentRemarkTable"/>
<xsl:copy>
<xsl:copy-of select="#*"/>
<xsl:element name="setTableRemarks">
<xsl:attribute name="remarks"
select="$originalChangeLog/key('remarkTableName', $currentRemarkTable)"/>
<xsl:attribute name="tableName" select="setTableRemarks/#tableName"/>
</xsl:element>
<xsl:copy-of select="*[not(self::setTableRemarks)]"/>
</xsl:copy>
</xsl:template>
</xsl:transform>
can somebody tell me how to map properly remark from external document?
I think you just want the identity transformation template you have plus
<xsl:template match="changeSet/setTableRemarks[key('remarkTableName', #tableName, $originalChangeLog)]/#remarks">
<xsl:attribute name="{name()}" select="key('remarkTableName', ../#tableName, $originalChangeLog)/#remarks"/>
</xsl:template>
https://xsltfiddle.liberty-development.net/6qVRKwR has an online sample (there the secondary XML is inlined as a variable for a self-contained example but if you keep your <xsl:variable name="originalChangeLog" select="document('/tmp/fixedremarks.xml')"/> it will work as well.

I'd like to add to output xml processed inside createChangelogTemplate to each element <changeSet> another attribute (context="legacy"). I was trying to add another template which matches databaseChangelog/changeSet with additional xsl:attribute element but that didn't worked for me. If is there way how to do this in one place that would be nice, because I will need to prepare more sections like CORE.
When I've added template:
<xsl:template match="changeSet" mode="legacy">
<xsl:copy>
<xsl:copy-of select="#*"/>
<xsl:attribute name="context">legacy</xsl:attribute>
<xsl:copy-of select="node()"/>
</xsl:copy>
</xsl:template>
and replaced <xsl:copy-of select="$changeLogContent"/> with <xsl:apply-templates select="$changeLogContent" mode="legacy"/> then output file core-changelog.xml was ok but file unmatched-changes-changelog.xml had no elements.
I'm using xslt 2.0 and saxon 9.8he.
When I run this I get changeSets 1 and 1-1 in core-changelog.xml, and changeSet 4 in unmatched-changelog.xml.
If you're still seeing nothing in unmatched-changelog then we need to look in more detail at exactly how you were running it.
Incidentally the selection of unmatched elements could be done as
select="changeSet except ($coreTablesVariable | $coreSequencesVariable | $coreIndexesVariable |$coreForeignConstraintsVariable |$coreViewsVariable)"/>

XSLT add attributes to processed nodes with output to result-document

this is sample xml:

</changeSet>
<changeSet id="4" author="A">
<createTable tableName="TABLE4">

I'm using xslt 2.0 and saxon 9.8he.
Use a separate mode i.e. instead of <xsl:copy-of select="$changeLogContent"/> use <xsl:apply-templates select="$changeLogContent" mode="legacy"/>, then set up e.g.
<xsl:template match="changeSet" mode="legacy">
<xsl:copy>
<xsl:copy-of select="#*"/>
<xsl:attribute name="context">legacy</xsl:attribute>
<xsl:copy-of select="node()"/>
</xsl:copy>
</xsl:template>
If further processing of the attributes and or the child nodes is necessary then change the <xsl:copy-of select="#*"/> and/or the <xsl:copy-of select="node()"/> to use xsl:apply-templates mode="#current" and set up further templates for the mode that perform any processing.

updating element name and value using XSLT

In context to my earlier question at "XSLT transformation from XML to XML document". Further i was trying
to rename the "<value>" element to "<sName>" along with updating the value to "ABC" if the value of "dataset/type/text() ='test'". I wrote below code
for the same but it was not working as expected. please help.

you would just use

or better
