<p>You can do a cut and past on every field and do the renaming:<br>
</p>
<p><br>
</p>
<p># For each marc field...<br>
</p>
<div>do marc_each()<br>
</div>
<div> # Cut the field into tmp..<br>
</div>
<div> marc_cut(***,tmp)<br>
</div>
<div><br>
</div>
<div> # Rename every 1 subfield to 0 <br>
</div>
<div> rename(tmp.*.subfields.*,1,0)<br>
</div>
<div><br>
</div>
<div> # And paste it back<br>
</div>
<div> marc_paste(tmp)</div>
<div>end<br>
</div>
<div><br>
</div>
<div>The `rename` fix allows regexes so you can replace '1' with any regex you like.<br>

<p class="MsoNormal">Hi</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"><span lang="EN-US">Is there an easy way to rename MARC subfield codes (not values) according to a regex condition? I am sure someone has an easy trick I just can’t find.
</span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">Case: Due to ALEPH internals, subfields holding identifiers are $1, not $0 as in the standard. I should change these in a conversion (MARC to MARC).</span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">Idea: </span></p>
<p class="MsoNormal"><span lang="EN-US">```</span></p>
<p class="MsoNormal"><span lang="EN-US">marc_cut(…1,tmp,equal:’regexthatmatchesidentifiers’)</span></p>
<p class="MsoNormal"><span lang="EN-US">rename(tmp, ‘1’, ‘0’)</span></p>
<p class="MsoNormal"><span lang="EN-US">marc_paste(tmp)</span></p>
<p class="MsoNormal"><span lang="EN-US">```</span></p>
<p class="MsoNormal"><span lang="EN-US">Downside is the positioning of the pasting, even with the at: parameter.</span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">Ideal would be a fix like ‘marc_rename’ that allows for a selection with a regex.</span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">Thanks for hints</span></p>
