我有一个 LibreOffice writer 文档，其中包含表单的文本片段prefix<...>。在 writer 中，我可以通过搜索正则表达式轻松找到它们：
现在，我想在 LibreOffice 外部的独立 python 脚本中使用 pyuno 制作所有这些事件的 python 列表。
我从各种来源收集的代码看起来像这样，到目前为止似乎可以工作：
import uno, os, time
SOCKET = 'socket,host=localhost,port=2002;urp;'
file = '/home/jochen/Dokumente/regexp_find_test.odt'
office_proc = os.popen('/usr/lib/libreoffice/program/soffice ' + file + ' --accept="' + SOCKET + 'StarOffice.ServiceManager"')
time.sleep(3)
localContext = uno.getComponentContext()
resolver = localContext.ServiceManager.createInstanceWithContext("com.sun.star.bridge.UnoUrlResolver", localContext)
try:
context = resolver.resolve('uno:' + SOCKET + 'StarOffice.ComponentContext')
except:
raise Exception("failed to connect to LibreOffice.org with socket {}".format(SOCKET))
loffice_desktop = context.ServiceManager.createInstanceWithContext("com.sun.star.frame.Desktop", context)
comp = loffice_desktop.getCurrentComponent()
search_descr = comp.createSearchDescriptor()
search_descr.SearchRegularExpression = True
search_descr.setSearchString('prefix<[a-z_]+>')
res = comp.findAll(search_descr)
print(len(res))
for n in range(len(res)):
print(40*'-')
print(res[n].Text.getText().getString())
我得到的输出让我感到惊讶，因为我使用了与 writer 相同的表达式：

我期待一些不错的东西

显然这个表达式表现得非常贪婪，有什么建议可以克服这个问题，还是我做错了什么？
