XSL include a non-looping element in a loop - xslt

Question

I have an XML-file that looks like this
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="gallring.xsl"?>
<report>
<title>Bibliography</title>
<dateCreated>2016-05-17</dateCreated>
<catalog>
<catalogKey>142343</catalogKey>
<yearOfPublication>1936</yearOfPublication>
<marc>
<marcEntry tag="100" label="Personal Author" ind="1 ">Landelius, Carl</marcEntry>
<marcEntry tag="245" label="Title" ind="00">1840-1850-talets bildningscirklar och arbetareföreningar i Sverige. 1</marcEntry>
</marc>
<call>
<callNumber>374</callNumber>
<library>VALLA</library>
<item>
<dateLastUsed>2009-01-06</dateLastUsed>
</item>
</call>
</catalog>
<catalog>
<catalogKey>661763</catalogKey>
<yearOfPublication>1936</yearOfPublication>
<marc>
<marcEntry tag="100" label="Personal Author" ind="1 ">Landelius, Carl</marcEntry>
<marcEntry tag="245" label="Title" ind="00">1840-1850-talets bildningscirklar och arbetareföreningar i Sverige / Carl Landelius</marcEntry>
</marc>
<call>
<callNumber>374</callNumber>
<library>VALLA</library>
<item>
<dateLastUsed>2014-06-18</dateLastUsed>
</item>
</call>
</catalog>
<catalog>
<catalogKey>32018</catalogKey>
<yearOfPublication>1982</yearOfPublication>
<marc>
<marcEntry tag="245" label="Title" ind="00">ABF-are berättar : minnen från ABF / red.: Allan Malmgren</marcEntry>
</marc>
<call>
<callNumber>374</callNumber>
<library>VALLA</library>
<item>
<dateLastUsed>2008-06-17</dateLastUsed>
</item>
</call>
</catalog>
To open it I use this stylesheet
<?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="/">
<catalog>
<xsl:for-each select="report/catalog">
<itemline>
<callNumber><xsl:text>"</xsl:text><xsl:value-of select="string(call/callNumber)"/><xsl:text>"</xsl:text></callNumber>
<yearOfPublication><xsl:value-of select="yearOfPublication"/></yearOfPublication>
<Author><xsl:value-of select="marc/marcEntry[#tag='100']"/></Author>
<Title><xsl:value-of select="substring(marc/marcEntry[#tag='245'],1,30)"/></Title>
<dateLastUsed><xsl:value-of select="call/item/dateLastUsed"/></dateLastUsed>
</itemline>
</xsl:for-each>
</catalog>
</xsl:template>
</xsl:stylesheet>
Problem is: I want to include the element title/dateCreated after each call/item/dateLastUsed-element so I can make calculations (in Excel) how many days has passed since dateLastUsed when the report was created.

Answer 1

There are different ways to include the dateCreated, e.g. you can add
<dateCreated><xsl:value-of select="../dateCreated"/></dateCreated>
As you are in a for-each loop for every report/catalog, this goes one step up from the current loop and fetches the information from the current report.
If the "real" XML only contains one report like in this example, you could also write
<dateCreated><xsl:value-of select="//report/dateCreated"/></dateCreated>
to target the dateCreated directly from root.
