Hi Matt, The W3C Recommendation for XPath has some good explanation and examples for abbreviated XPath syntax here: http://www.w3.org/TR/xpath-30/#abbrev Katie -----Original Message----- From: Code for Libraries [mailto:[log in to unmask]] On Behalf Of Matthew Sherman Sent: Friday, July 11, 2014 10:39 AM To: [log in to unmask] Subject: [CODE4LIB] OAI Crosswalk XSLT Hi Code4Lib folks, I have a question for those of you who have worked with OAI-PMH. I am currently editing our DSpace OAI crosswalk to include a few custom metadata field that exist in our repository for publication information and port them into a more standard format. The problem I am running into is the select statements they use are not the typical XPath statements I am used to. For example: <xsl:for-each select="doc:metadata/doc:element[@name='dc']/doc:element[@name='type']/doc:element/doc:element/doc:field[@name='value']"> <dc:type><xsl:value-of select="." /></dc:type> </xsl:for-each> I know what the "." does, but the other select statement is a bit foreign to me. So my question is, does anyone know of some reference material that can help me make sense of this select? I need to understand what it is doing so I can make my own. Thanks for any insight you can provide. Matt Sherman
