  • 循环引用检测

Implementations§

Source§

impl XmlSchemaParser

Source

pub fn parse_from_str(xml_content: &str) -> XmlSchemaResult<SchemaSpec>

从XML字符串解析Schema定义

这是最基础的解析方法,适用于单一XML文件的解析

§参数
  • xml_content - XML格式的schema定义字符串
§返回值
  • XmlSchemaResult<SchemaSpec> - 解析后的SchemaSpec或错误
§示例
use mf_core::schema_parser::XmlSchemaParser;
 
let xml = r#"
<?xml version="1.0" encoding="UTF-8"?>
<schema top_node="doc">
  <nodes>
    <node name="doc">
      <content>paragraph+</content>
    </node>
  </nodes>
</schema>
"#;
 
let schema_spec = XmlSchemaParser::parse_from_str(xml)?;
Source

pub fn parse_from_file(file_path: &str) -> XmlSchemaResult<SchemaSpec>

从XML文件解析Schema定义

适用于单一XML文件的解析,会读取文件内容后调用parse_from_str

§参数
  • file_path - XML文件路径
§返回值
  • XmlSchemaResult<SchemaSpec> - 解析后的SchemaSpec或错误
Source

pub fn parse_to_extensions( xml_content: &str, ) -> XmlSchemaResult<Vec<Extensions>>

从XML字符串解析为Extensions列表

将XML Schema转换为ModuForge可直接使用的Extensions格式 支持自动检测XML格式(是否包含引用)

§参数
  • xml_content - XML格式的schema定义字符串
§返回值
  • XmlSchemaResult<Vec<Extensions>> - 解析后的Extensions列表或错误
§示例
use mf_core::schema_parser::XmlSchemaParser;

let xml = r#"
<?xml version="1.0" encoding="UTF-8"?>
<schema top_node="doc">
  <nodes>
    <node name="doc">
      <content>paragraph+</content>
    </node>
  </nodes>
</schema>
"#;

let extensions = XmlSchemaParser::parse_to_extensions(xml)?;
Source

pub fn parse_extensions_from_file( file_path: &str, ) -> XmlSchemaResult<Vec<Extensions>>

从XML文件解析为Extensions列表

单文件版本的Extensions解析方法

§参数
  • file_path - XML文件路径
§返回值
  • XmlSchemaResult<Vec<Extensions>> - 解析后的Extensions列表或错误
Source

pub fn parse_multi_file(file_path: &str) -> XmlSchemaResult<SchemaSpec>

从XML文件解析Schema定义(支持多文件引用)

这是最强大的解析方法,支持:

  • import引用(合并到当前schema,不允许覆盖)
  • include引用(内联包含,允许覆盖)
  • 相对路径解析
  • 循环引用检测
  • 深度限制保护
§参数
  • file_path - 主XML文件路径
§返回值
  • XmlSchemaResult<SchemaSpec> - 解析后的SchemaSpec或错误
§示例
use mf_core::schema_parser::XmlSchemaParser;

// 解析支持import/include的schema文件
let schema_spec = XmlSchemaParser::parse_multi_file("./schemas/main.xml")?;
Source

pub fn parse_multi_file_to_extensions( file_path: &str, ) -> XmlSchemaResult<Vec<Extensions>>

从XML文件解析为Extensions列表(支持多文件引用)

§参数
  • file_path - 主XML文件路径
§返回值
  • XmlSchemaResult<Vec<Extensions>> - 解析后的Extensions列表或错误
Source

pub fn parse_file_to_extensions_with_context( file_path: &str, context: &mut MultiFileParseContext, ) -> XmlSchemaResult<Vec<Extensions>>

使用上下文解析文件为Extensions(支持global_attributes)

Source

pub fn parse_file_with_context( file_path: &str, context: &mut MultiFileParseContext, ) -> XmlSchemaResult<SchemaSpec>

使用上下文解析文件(支持引用)

Source

pub fn convert_to_extensions_from_spec( schema_spec: SchemaSpec, ) -> XmlSchemaResult<Vec<Extensions>>

从SchemaSpec转换为Extensions

Source

pub fn parse_attribute_value(value_str: &str) -> XmlSchemaResult<Value>

解析属性默认值
