<td align="center" style="border-width:1px;border-style:solid;font-size:x-small;width:40px;"> <span id="gridview1__anzahlplaetze_0" title="anzahl plätze" readonly="true" style="display:inline-block;border-width:0px;font-family:verdana,geneva,arial,helvetica,sans-serif;font-size:x-small;">810</span> </td> i did try use regex did not work out me.
i suggest use xml/html parser supports css selectors retrieve string, since span contains string has id = "gridview1__anzahlplaetze_0", , can use query "#gridview1__anzahlplaetze_0" retrieve it.
for example, swift library called fuzi wraps libxml2
import fuzi let doc = try? htmldocument(string: htmlstring) if let result = doc?.firstchild(css: "#gridview1__anzahlplaetze_0") { print(result.stringvalue) } the above code tested.
