10.3.36 getXmlAttrValue (obtains an attribute value of elements of XML data)

Syntax

getXmlAttrValue  [-e character-encoding]  element-name  attribute-name  [file-path-name]

Description

This command searches for element name from the XML file specified for argument and outputs all fully matched attribute values. Output is performed after deleting line breaks contained in attribute values.

Arguments

-e character-encoding

Windows edition

This command specifies the character encoding for XML files. "SJS" or "UTF8" can be specified. If you do not specify this option, the character encoding is treated as UTF8.

UNIX edition

This command specifies the character encoding for XML file with the syntax of value of the environment variable LANG. For values that can be specified, see 2.2.4 Encoding used in JP1/Advanced Shell.

If you do not specify this option, assume that the character encoding is specified in the format of the value of the LANG environment variable in the environment where JP1/Advanced Shell operates.

For example, if the XML file with the character encoding UTF-8 in AIX is treated, specify "JA_JP" or "JA_JP.UTF-8" for -e option.

element-name

This command specifies the element name with attribute.

attribute-name

This command specifies the attribute name to be searched.

file-path-name

This command specifies the path of a XML file. If you do not specify the file path name, input from the standard input.

Output to the standard output

Attribute values of elements of XML data.

Return codes

Notes

• If matching elements or attributes are not found, the command terminates with an error.

• If metacharacter in the regular expression is included in the element name or attribute name, specify the element name by escaping with \.

  Example:

  This command is specified as follows when you search for the attribute name "id*" in the element name "name+".

  getXmlAttrValue 'name\+' 'id\*' test.xml

• This part creates a temporary file by using the adshmktemp command. Therefore, the temporary file might remain when the command receives a forced termination request while the part is being executed. In this case, delete the temporary file manually. Temporary file is created in the directory defined with the TEMP_FILE_DIR parameter of the temporary file according to the following naming rule:

  getXmlAttrValue_job-ID_process-ID_time-information_file-sequence-number

Examples
