Problem Note 33261: %TMFILTER macro does not find links when URL= uses single quotes
 |  |  |  |  |
The %TMFILTER macro, included with SAS® Text Miner, supports the URL= parameter for extracting text content from web pages. The filtering engine should begin at the page referenced by the URL= parameter, then "crawl" to each page linked.
However, if the HTTP reference tag quotes the URL address using single–quote characters, the link is ignored and its pages are omitted from the %TMFILTER output.
There are no errors or warnings indicating that links were overlooked. To determine whether the problem occurred, examine the %TMFILTER output to see if it contains fewer observations than you expected.
The problem does not occur for HTTP reference tags that use double–quotes.For example, %TMFILTER will not follow the link to the resources page if the HTTP reference tag is written like this:
<a href='/resources'>Company Resources</a>
The same link written with double-quotes works:
