Developer FAQ
I would like to use strings as part of a link address (URL), but writing the following XSLT does not generate the result I desire, if the value of @Title contains characters like '?' or '#' - and XSLT 1.0 does not contain any functions for URL encoding.
<a href="?title={@Title}">sample like</a>Does C1 offer any solution to this problem?
Answer:
C1's XSLT feature allow you to execute C# functions 'inline' and C# contains a large number of functions for web oriented encoding and decoding. The following XSLT show how C# is invoked to URL encode a string:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" exclude-result-prefixes="xsl in msxsl csharp" xmlns:in="http://www.composite.net/ns/transformation/input/1.0" xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:csharp="http://c1.composite.net/sample/csharp" xmlns="http://www.w3.org/1999/xhtml">
<xsl:template match="/">
<html>
<head />
<body>
<a href="?{csharp:UrlEncodeUnicode('Is C# url friendly?')}">
Link with reserved characters
</a>
</body>
</html>
</xsl:template>
<msxsl:script implements-prefix="csharp" language="C#">
<msxsl:assembly name="System.Web" />
<msxsl:using namespace="System.Web" />
public String UrlEncodeUnicode(string source)
{
return HttpUtility.UrlEncodeUnicode(source);
}
</msxsl:script>
</xsl:stylesheet>
