I have a question about displaying shields on highways. Table 4.4 in the Conversion Style Manual shows highway shields displaying numbers only, which is what I would like to achieve. In Table 4.3 (the list of substitution filters), the description for the highway-symbol filter says that the filer "Prepares the value as a highway reference such as 'A21' 'I-80' and so on. A code is added to the front of the string so that a highway shield is displayed, spaces are removed and the text is truncated so as not to overflow the symbol." The description does not explain (from what I can tell) how to remove the alphabetic characters, leaving only the numbers. I've tried several possibilities of the filter without success. Where I live, there's a motorway called Interstate 70 which is labeled "I70" in OSM. I would like to create shields with only the number in the shields, similar to the example in Table 4.4. How do I do this?<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Candara",sans-serif;color:black'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-family:"Candara",sans-serif;color:black'>Mark<o:p></o:p></span></p></div></body></html>
