XSLT to extract URL Parameters - xslt

Question

can anyone help me to find a way to extract some parameters from URL and save pass it into soap request
URL
https://hostname/ServiceName?Consumer=ABS&ID=3231
I'd take only Consumer name which is ABS and it's id = 3231 and put it into soap as below
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<Consumer>ABS</Consumer>
<ID>3231<ID>
</soapenv:Body>
</soapenv:Envelope>

Answer 1

In XSLT 2.0 or higher, you can use the xsl:analyze-string instruction to extract all query parameters from a URL string:
<xsl:analyze-string select="$URL" regex="[\?&]([^=]+)=([^&]+)">
<xsl:matching-substring>
<xsl:element name="{regex-group(1)}">
<xsl:value-of select="regex-group(2)" />
</xsl:element>
</xsl:matching-substring>
</xsl:analyze-string>

Answer 2

if you want to use string formatting functions along with hard coded element name in result
<xsl:variable name="URL">https://hostname/ServiceName?Consumer=ABS&ID=3231</xsl:variable>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<Consumer>
<xsl:value-of select="substring-before(substring-after($URL,'Consumer='),'&')"/>
</Consumer>
<ID>
<xsl:value-of select="substring-after($URL,'ID=')"/>
</ID>
</soapenv:Body>
</soapenv:Envelope>
