How to shorten filename displayed in DSpace

问题

I would like to shorten the file name that is being displayed in the simple item view.

If I have a very long file name, this is displayed in the simple item record:

This example file name is shortened if you view the full item record:

But if you edit this item and click the Item Bitstreams tab, the file name is being displayed like this:

My goal is to apply what is being displayed in the edit bitstream (the 3rd picture) to the simple and full item view. I don't know where this transformation is being generated. I looked at administrative.xsl and I can't find anything on the shortening of the file name. Please advice on how to achieve this or where to look for this transformation.

回答1:

The rewrite of the file name in the "Item Bitstreams" tab is done in Java code, not in the XSL. It's here: EditItemBitstreamsForm.java.

Your item page screenshot looks like you're working in XMLUI / Mirage 2, is that right? Your best bet is to use the shortenString method in org.dspace.app.xmlui.utils.XSLUtils (code). Actually maybe you aren't using Mirage 2 because Mirage 2 does just that, see item-view.xsl:

<xsl:value-of select="util:shortenString(mets:FLocat[@LOCTYPE='URL']/@xlink:title, 30, 5)"/>

Thanks to Andrea for the answer. Here's my code and how I used it.

I created a new method shortenFileName in org.dspace.app.xmlui.utils.XSLUtils

    public static String shortenFileName(String string, String middle, int targetLength) {
        targetLength = Math.abs(targetLength);

        if (string != null && string.length() > targetLength) {
            // If the file name is too long then shorten it so that it will display nicely.
            return StringUtils.abbreviateMiddle(string, middle, targetLength);
        }
        else
            return string;
    }

and then used it in item-view.xsl like this:

<xsl:value-of select="util:shortenFileName(mets:FLocat[@LOCTYPE='URL']/@xlink:title, ' &#8230; ', 20)" />

The file name now looked like this:
