如果它的子节点在rdf:Description[@rdf:about]
元素中包含THUMBNAIL
的值,我想提取dcterms:description
的首次出现的值。因此,在上面的示例xml输入中,我想提取https://repository.seafdec.org.ph/bitstream/10862/152/32/ediblecrustacea.pdf.jpg
编辑:
此帖子与我之前的帖子有关:How to display thumbnails from harvested items in DSpace?
基本上,我要实现的是将提取的值作为图像标签的src
。因此,在点击该向下投票之前,请花点时间阅读该链接的帖子。
谢谢。
