8.1.1 About specification in XML format
The measurement condition registration file, command registration file, and Web transaction files are created in XML format. The following points must be noted when you create definition files in XML format.
- Start and end tags
-
XML tags must always be paired (start tag and end tag). If the end tag is missing for a specified start tag, or vice versa, an error results. Within a tag enclosed by angle brackets (< and >), you cannot specify any codes other than the tag name (such as spaces, tabs, or linefeed characters).
- Element
-
The coding enclosed by a start tag and an end tag constitutes an element.
<SAMPLE_TAG>..element..</SAMPLE_TAG>
The start tag must have a corresponding end tag. In the example above, if <SAMPLE_TAG> were not accompanied by the corresponding </SAMPLE_TAG>, an error would result.
If there is no element, the start and end tags can be combined as follows:
<SAMPLE_TAG/>
- Case
-
XML coding is case sensitive. You must enter all information exactly as shown in the definition file format.
- Deletion of space, tab, and linefeed characters
-
Space, tab, and linefeed characters that were entered before or after an element are deleted; they are not treated as part of the element.
- Characters requiring replacement
-
The characters listed below are reserved characters in the XML syntax. To use these characters as part of an element, they must be replaced with the indicated character strings.

- Specification of a comment
-
You can specify a comment in following format:
<!--comment-->
A comment text cannot contain two hyphens in succession (--).
- Linefeed code
-
A linefeed code in a text is treated as LF(0x0a). To treat it as CRLF(0x0d0a), use 
 instead of the linefeed code.
