Subject: encapsulating all record fields in a xsl:for-each to prevent emitting empty
X-Git-Tag: PAZPAR2.1.0.0~268
X-Git-Url: http://lists.indexdata.dk/?a=commitdiff_plain;h=bc3ce0aac8385dc44e988ce953e93ba6b0ae1450;p=pazpar2-moved-to-github.git

encapsulating all record fields in a xsl:for-each to prevent emitting empty
<md-title> elements. Now all emitted elements have always content, and the final web client JS does not break any more.
