An Avro binary file contains an Avro data block preceded by the Avro schema that defines the structure of the data block. The avroextractschema command extracts the Avro schema from the Avro binary and serializes the Avro schema as JSON.
raptorxml avroextractschema [options] --avrooutput=AvroSchemaFile AvroBinaryFile |
•The AvroBinaryFile argument specifies the Avro binary file from which the Avro schema is to be extracted.
•The --avrooutput option specifies the location of the extracted Avro schema.
Example
Example of the avroextractschema command:
•raptorxml avroextractschema --avrooutput=c:\MyAvroSchema.avsc c:\MyAvroBinary.avro
RaptorXML (and RaptorXMLServer for administration commands) on Windows raptorxml (and raptorxmlserver for administration commands) on Windows and Unix (Linux, Mac) * Note that lowercase (raptorxml and raptorxmlserver) works on all platforms (Windows, Linux, and Mac), while upper-lower (RaptorXML) works only on Windows and Mac. * Use forward slashes on Linux and Mac, backslashes on Windows. |
On Windows systems: When spaces or special characters occur in strings (for example in file or folder names, or company, person or product names), use quotes: for example, "My File". Note, however, that a backslash followed by a double-quotation mark (for example, "C:\My directory\") might not be read correctly. This is because the backslash character is also used to indicate the start of an escape sequence, and the escape sequence \" stands for the double-quotation mark character. If you want to escape this sequence of characters, use a preceding backslash, like this: \\". To summarize: If you need to write a file path that contains spaces or an end backslash, write it like this: "C:\My Directory\\". |
Options
Options are listed in short form (if available) and long form. You can use one or two dashes for both short and long forms. An option may or may not take a value. If it takes a value, it is written like this: --option=value. Values can be specified without quotes except in two cases: (i) when the value string contains spaces, or (ii) when explicitly stated in the description of the option that quotes are required. If an option takes a Boolean value and no value is specified, then the option's default value is TRUE. Use the --h, --help option to display information about the command.
--output = FILE, --avrooutput = FILE Sets the location of the Avro output file. |
--recurse = true|false Used to select files within sub-directories, including in ZIP archives. If true, the command's InputFile argument will select the specified file also in subdirectories. For example: "test.zip|zip\test.xml" will select files named test.xml at all folder levels of the zip folder. References to ZIP files must be given in quotes. The wildcard characters * and ? may be used. So, *.xml will select all .xml files in the (zip) folder. The option's default value is false. Note: Boolean option values are set to true if the option is specified without a value. |
|
--catalog = FILE Specifies the absolute path to a root catalog file that is not the installed root catalog file. The default value is the absolute path to the installed root catalog file (<installation-folder>\Altova\RaptorXMLServer2025\etc\RootCatalog.xml). See the section, XML Catalogs, for information about working with catalogs. |
--user-catalog = FILE Specifies the absolute path to an XML catalog to be used in addition to the root catalog. See the section, XML Catalogs, for information about working with catalogs. |
--enable-globalresources = true|false Enables global resources. Default value is false. Note: Boolean option values are set to true if the option is specified without a value. |
|
--error-format = text|shortxml|longxml Specifies the format of the error output. Default value is text. The other options generate XML formats, with longxml generating more detail. |
--error-limit = N | unlimited Specifies the error limit with a value range of 1 to 9999 or unlimited. The default value is 100. Processing stops when the error limit is reached. Useful for limiting processor use during validation/transformation. |
--info-limit = N | unlimited Specifies the information message limit in the range 1-65535 or unlimited. Processing continues if the specified info limit is reached, but further messages are not reported. The default value is 100. |
--help Displays help text for the command. For example, valany --h. (Alternatively the help command can be used with an argument. For example: help valany.) |
--listfile = true|false If true, treats the command's InputFile argument as a text file containing one filename per line. Default value is false. (An alternative is to list the files on the CLI with a space as separator. Note, however, that CLIs have a maximum-character limitation.) Note that the --listfile option applies only to arguments, and not to options. Note: Boolean option values are set to true if the option is specified without a value. |
--log-output = FILE Writes the log output to the specified file URL. Ensure that the CLI has write permission to the output location. |
--network-timeout = VALUE Specifies the timeout in milliseconds for remote I/O operations. Default is: 40000. |
--recurse = true|false Used to select files within sub-directories, including in ZIP archives. If true, the command's InputFile argument will select the specified file also in subdirectories. For example: "test.zip|zip\test.xml" will select files named test.xml at all folder levels of the zip folder. References to ZIP files must be given in quotes. The wildcard characters * and ? may be used. So, *.xml will select all .xml files in the (zip) folder. The option's default value is false. Note: Boolean option values are set to true if the option is specified without a value. |
--verbose = true|false A value of true enables output of additional information during validation. Default value is false. Note: Boolean option values are set to true if the option is specified without a value. |
--verbose-output = FILE Writes verbose output to FILE. |
--version Displays the version of RaptorXML Server. If used with a command, place --version before the command. |
--warning-limit = N | unlimited Specifies the warning limit in the range 1-65535 or unlimited. Processing continues if this limit is reached, but further warnings are not reported. The default value is 100. |
