create_footnote_string

Takes the text for a footnote, and returns a string with the correct formatting. You can use this if you want to add the footnote to a string. Currently, the newline replacement options are restricted to LINEBREAK and NONE. The reserved characters <, > and & will be escaped temporarily, but they will be correctly displayed in DSP-APP.

Attention
  • The text in the footnote may be richtext, i.e. contain XML tags.
  • Not all tags supported in ordinary richtext are currently implemented.
  • The allowed tags are:
    • <br> (break line)
    • <strong> (bold)
    • <em> (italic)
    • <u> (underline)
    • <strike> (strike through)
    • <a href="URI"> (link to a URI)
    • <a class="salsah-link" href="Knora IRI"> (link to a resource)

Parameters:

Name Type Description Default
footnote_text str

Text for the footnote

required
newline_replacement_option NewlineReplacement

options to replace newlines

LINEBREAK

Returns:

Type Description
str

The footnote as a string

Examples:

result = xmllib.create_footnote_string("Text")
# result == '<footnote content="Text"/>'
result = xmllib.create_footnote_string("Text\nSecond Line")
# result == '<footnote content="Text&lt;br/&gt;Second Line"/>'
result = xmllib.create_footnote_string("Already escaped &lt;&gt;")
# already escaped characters will not be escaped again
# result == '<footnote content="Already escaped &lt;&gt;"/>'

The string must contain at least one Unicode letter (matching the regex \p{L}), _, !, ?, or number, but must not be None, <NA>, N/A, or -.

Parameters:

Name Type Description Default
input_value str | float | int

input value

required

Returns:

Type Description
str

an xsd ID based on the input value, with a UUID attached.

Examples:

result = xmllib.make_xsd_compatible_id_with_uuid("Universität_Basel")
# result == "Universit_t_Basel_88f5cd0b-f333-4174-9030-65900b17773d"
