I'm dealing with a bunch of bibliographical entries (to be more precise, journal articles) described by the DublinCore metadata system. What I'm trying to do is retrieve these data and rearrange them in a consistent XML structure, in order to create XML files which meet the PKP specifications and can be uploaded to my OJS installation.
Although I had never approached XSLT before, after a couple of days of studying, this is what I managed to get:

</issue>
and so on...
Basically I would like to copy the <language/>
text node for each <articleItem/>
and paste it as the attribute value (marked with ##) of the elements articleItem
, galley
(HTML) and galley
(PDF).
I tried a lot of different solutions, but none of them worked for me: actually I'm wondering whether it is possible to get this result...
So I'm a little bit stuck here; any help would be appreciated. Thank you in advance.

edit after @michael.hor257k posted a comment:
This is my try, but I know that it doesn't make sense at all, because I'm not manipulating, but just creating a copy of an element that already exists...
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" encoding="UTF-8" version="1.0" doctype-public="-//PKP//OJS Articles and Issues XML//EN" doctype-system="http://pkp.sfu.ca/ojs/dtds/2.4.7/native.dtd"/>
<xsl:template match="@*|node()">

<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="language">
<articleItem locale="it_IT" public_id="" language="{node()}"/>
</xsl:template>
</xsl:stylesheet>
I'm not able to solve this problem:
This is the result that I'm trying to get:

Note that the language
element is not displayed anymore, but its text node is now the attribute value of articleItem
[language="en|fr|es"], galley
(HTML) and galley
(PDF) [both => locale="en|fr|es"]
Try it this way:
XSLT 2.0
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<!-- identity transform -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<!-- populate articleItem's language -->
<xsl:template match="articleItem/@language">
<xsl:attribute name="language" select="../language"/>
</xsl:template>
<!-- populate galley's locale -->
<xsl:template match="galley/@locale">
<xsl:attribute name="locale" select="ancestor::articleItem/language"/>
</xsl:template>
<!-- remove language -->
<xsl:template match="language"/>
</xsl:stylesheet>
but what if the attribute name and its value were not set? For instance:
<articleItem locale="it_IT">...</articleItem>
(without "language" attribute) and<galley>...</galley>
(without "locale" attribute)
In such case the template would have to match the parent element ( articleItem
or galley
), copy it, copy the existing attributes, add/overwrite the language
attribute and apply templates to child nodes - for example:
<xsl:template match="articleItem">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:attribute name="language" select="../language"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
