[oXygen-user] Feature request: Validation for linked images in SVG paths

[Alex Jitianu]

Hello  Matt,

In Oxygen v15.0 we've added in the "Validate and check for Completeness" 
dialog a new entry called "Additional schematron checks" in which you 
can specify additional Schematron checks that should be be executed on 
the topics. You can perform the check you've described using a 
Schematron file with the following content:

<?xml version="1.0" encoding="UTF-8"?>
<schema
     xmlns="http://purl.oclc.org/dsdl/schematron"
     queryBinding="xslt2"
     xmlns:exslt="http://expath.org/ns/file">
     <ns uri="http://expath.org/ns/file" prefix="exslt"/>
     <pattern>
         <rule context="image[ends-with(@href, '.svg')]">
             <let name="svgDocument" value="document(@href)" />
             <assert 
test="exslt:exists(resolve-uri($svgDocument//*:image/@*:href, 
base-uri($svgDocument)))">
                 The image file from the following SVG doesn't exist: 
<value-of select="base-uri($svgDocument)"/></assert>
         </rule>
     </pattern>
</schema>

Best regards,
Alex
