# 或者: from yaml.constructor.SafeConstructor import add_constructor [as 别名]
def parse(self, content, **kwargs):
""" Parses the given YAML content to create stringset and template
Steps are:
1. Load yaml content using our custom loader TxYamlLoader that
in addition to the value for each key notes the `start` and
`end` index of each node in the file and some metadata.
2. Flattens the output of the loader to be a list of the form:
```
[{
'key': 'string_key1',
'value': 'string1',
'end': <end_index_of_node>,
'start': <start_index_value>,
'style': '|, >, ...'
},
...
]
```
3. Iterates over the flattened list and for each entry creates an
OpenString object, appends it to stringset and replace its value
with the template_replacement in the template.
4. Returns the (template, stringset) tuple.
