The Complete Guide to the SAS Output Delivery System |
The HTML destination can produce four kinds of files: body, contents, frame, and page files. You create these files with options in the ODS HTML statement (see ODS HTML Statement for details).
The Body File |
Typically, when you route an output object that does not contain graphics to the HTML destination, ODS places the results within TABLE tags, rendering them as one or more HTML tables.
Graphics output is produced according to the SAS code that generates it. Instead of using <TABLE> tags, the body file contains an <IMG> (image) tag that references the graphic. When you view the body file in a browser, you cannot tell that the graphic is not part of the body file because the <IMG> tag displays it in the browser.
Note: A very few procedures produce output objects that are neither tabular nor
graphics. In these cases, the output is not tagged as an HTML table.
Titles and footnotes in the body file are rendered as HTML tables of their own near the top and bottom of each page of HTML output.
Note: For graphics output, titles and footnotes are, by default,
part of the graphics file. You can use the NOGTITLE and NOGFOOTNOTE options
to place them in the body file instead. See the discussion of GTITLE and
GFOOTNOTE for more information.
All <TABLE> tags and all <IMG> tags are potential targets for links or references (see HTML Links and References). Therefore, ODS must provide an <A> tag with a NAME attribute close to each <TABLE> and <IMG> tag for links and references to point to. The NAME attribute on the anchor tag becomes the final part of any reference or link to the table. ODS inserts anchor tags in its HTML output as follows:
Note: Each procedure or DATA step starts a new page. In addition, ODS produces a
new page of output whenever the SAS program explicitly asks for a new page.
For example, if you use the page dimension in PROC TABULATE, you create a
page for each value of the variable that defines the pages. In this context,
the word page has nothing to do with the PAGESIZE= setting in your SAS session.
Placement of <A> (anchor) Tags in HTML Output
For a view of this same file through a browser, see HTML Frame File.
The Contents File |
The contents file contains a link to the body file for each HTML table that ODS creates from procedure or DATA step results. The targets for these links are the values of the NAME attributes on the anchor tags that are in the body file (see The Body File). For example, an anchor tag that links to the second HTML table of results in Placement of <A> (anchor) Tags in HTML Output looks like this:
<A href="pop-body.htm#IDX1">In this anchor tag
You can view the contents file directly in the browser, or, if you make a frame file, you can see the contents file as part of the frame file (see The Frame File).
The Page File |
The page file contains a link to the body file for each page of HTML output that ODS creates from procedure or DATA step results. The targets for these links are the values of the NAME attributes on the anchor tags that are in the body file (see The Body File). For example, an anchor tag that links to the second page of results in Placement of <A> (anchor) Tags in HTML Output looks like this:
<A href="pop-body.htm#IDX2">In this anchor tag
You can view the page file directly in the browser, or, if you make a frame file, you can see the page file as part of the frame file (see The Frame File).
The Frame File |
The frame file provides a simultaneous view of the body file and the contents file, the page file, or both. The following figure illustrates how a frame that references both the contents and page files looks (in part) to an ASCII editor. The SRC attribute identifies a file to display in the browser. ODS constructs the value for the SRC attribute the same way that it constructs the value for an HREF attribute in a page or contents file (see The Contents File).
