organoid_tracker.util.xml_wrapper module

An XML wrapper for easier parsing. It allows you to safely write code like this:

metadata[“ImageDocument”][“Metadata”][“Scaling”][“Items”][“Distance”].value_float()

If any of the elements in the chain doesn’t exist, you will just end up with None at the end, instead of crashing halfway through.

An XML wrapper for easier parsing. It allows you to safely write code like this:

metadata[“ImageDocument”][“Metadata”][“Scaling”][“Items”][“Distance”].value_float()

One limitation is that you can’t extract text from elements that have both text and subelements.

attr_float(name: str) → Optional[float]

Same as attr_str, but returned as a float. Returns None if the attribute was not found, or couldn’t be parsed as a float.

attr_str(name: str) → Optional[str]

Returns the value of the attribute with the given name. If the attribute doesn’t exist, returns None.

is_none() → bool

Checks if this element is equal to NONE_ELEMENT.

value_float() → Optional[float]

If this tag has just one text node as a child, returns its value as a float. If the value is not a valid float, returns None.

value_str() → Optional[str]

If this tag has just one text node as a child, returns its value. Otherwise, returns None.
