Libreoffice将docx文本字段表示为字段标记 .

我可以使用以下MWE通过UNO桥创建它们：

# to connect as client`

import uno
from pythonscript import ScriptContext

resolver = uno.getComponentContext().ServiceManager.createInstance('com.sun.star.bridge.UnoUrlResolver')
# start libreoffice as
# libreoffice --writer --accept="socket,host=localhost,port=2002;urp;"`
client = resolver.resolve('uno:socket,host=localhost,port=2002;urp;StarOffice.ComponentContext')

XSCRIPTCONTEXT = ScriptContext(client, None, None)
doc = XSCRIPTCONTEXT.getDocument()

def cursor():
    return doc.getCurrentController().getSelection().getByIndex(0)

t = doc.getText()
# insert text before field
t.insertString(cursor(), 'Fieldmark-Start|', False)

# create the field
field = doc.createInstance('com.sun.star.text.Fieldmark')

fieldcursor = cursor()
# add the String 'Field contents' to the document
fieldcursor.setString('Field contents')

# actually insert the field in the document (linked to the string)
field.attach(fieldcursor)
field.setFieldType('Testfieldtype')
field.setName('Fieldname')

# insert text after the field
t.insertString(cursor(), '|Fieldmark-End', False)

保存后，段落将正确保存为

<text:p text:style-name="Standard">Fieldmark-Start|
    <field:fieldmark-start text:name="Fieldname" field:type="Testfieldtype"/>
        Field contents
    <field:fieldmark-end/>
|Fieldmark-End</text:p>

但是，我在文档中找不到任何现有的字段标记：

# check if the contents are there
doc.getText().getString()
# -> 'Fieldmark-Start|Field contents|Fieldmark-End'

# try to enumerate all fields
tf = doc.getTextFields()
tf.hasElements() # -> true
enum = tf.createEnumeration()
enum.hasMoreElements() # -> false

# field = enum.nextElement()
# -> com.sun.star.container.NoSuchElementException
python libreoffice uno libreoffice-writer

    即使它们没有出现在 doc.getTextFields() 或 doc.getBookmarks() 中，仍然可以通过枚举文本来找到它们 .

    paragraphs = t.createEnumeration()
while paragraphs.hasMoreElements():
    text_portions = paragraphs.nextElement().createEnumeration()
    while text_portions.hasMoreElements():
        text_portion = text_portions.nextElement()
        if text_portion.TextPortionType == "TextFieldStart":
            bookmark = text_portion.Bookmark
            bookmark.Name
            bookmark.FieldType

    结果：

    'Fieldname'
'Testfieldtype'

    从这一点开始，请遵循UNO API文档，例如https://wiki.openoffice.org/wiki/Documentation/DevGuide/Text/Bookmarks .
