Convert XSLT Structure

Operation Name

Function overview

Converts input data with XSLT.

Data Model

Data model of this component is XML type.

Refer to "Schema" for input/output schema.

Properties

For information about using variables, refer to "variables".

Basic settings

Item name	Required/Optional	Use of Variables	Description	Remarks
Name	Required	Not available	Enter the name on the script canvas.
Input data	Required	Not available	Select the component on the script canvas.

Required settings

Item name	Required/Optional	Use of Variables	Description	Remarks
XSLT read type	Required	Not available	Select whether to read XSLT from a file or input directly. [FILE]:(default) Select in case of reading XSLT from a file.Create XSLT file in advance. [TEXT]: Select in case of inputting XSLT directly.	Corresponding to the selected specifying method, the input field switches to [XSLT file]/[XSLT text].
XSLT file	Required	Available	Enter the path of the XSLT file. Click [Browse] button to activate the file Selectr and Select the file.	Enabled when [FILE] is selected in [XSLT read type]. Please specify the absolute path of the DataSpider file system as the file path. Constrained characters of DataSpider File System cannot be used except for path separator "/".
XSLT text	Required	Available	Enters XSLT directly.	Enabled when [TEXT] is selected in [XSLT read type].

Data processing method

Item name	Required/Optional	Use of Variables	Description	Remarks
Data processing method	Required	Not available	Select a data processing method. [Use script settings]: (default) Apply mass data processing settings of script property to adapter. [Disable]: Mass data processing is not performed. [Enable]: Mass data processing is performed.

Comment

Item name	Required/Optional	Use of Variables	Description	Remarks
Comment	Optional	Not available	You can write a short description of this adapter. The description will be reflected in the specifications.

Schema

The scheme differs from the processing contents of XSLT.

Mass data processing

Mass data processing is supported.

Conversion by XSLT holds input data in the memory as string for once. If the input data is too large, even if you Select [Enable], OutOfMemoryError might occur. In that case you need to ensure DataSpiderServer heap size.

Refer to "Property Reference" for the method of changing the heap size of DataSpiderServer.

PSP Usage

PSP is not supported.

Component variable name	Description	Remarks
message_category	Stroes the category to which corresponding message code belongs to, when an error occurs.	The value defaults to null.
message_code	Stores its corresponding message code of occured error.	The value defaults to null.
message_level	Stores the severity of the corresponding message code of the occured error.	The value defaults to null.
