Subject: [xsl] tokenizing comma separated string with quotes
Given the input
<elem>"foo, bar", baz, bom</elem>
Is there a nice one liner / technique to return the three
tokens "foo, bar" "baz" "bom"
eg:
<root>
<token>foo, bar</token>
<token>baz</token>
<token>bom</token>
</root>
I can't see the answer for all the apparent quote escaping required...
If you are using XSL 2.0, this should work:
Input file:
<elem>"foo, bar", baz, bom</elem>
Transform file:
<xsl:transform version="2.0"
exclude-result-prefixes="xsd xsi xsl"
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
<xsl:output method="xml" version="1.0"
media-type="text/xml" encoding="utf-8"
omit-xml-declaration="yes" indent="yes"
/>
<xsl:variable name="regex">
<xsl:text>\s*("[^"]*"|[^,]+)\s*</xsl:text>
</xsl:variable>
<xsl:template match="/">
<root>
<xsl:analyze-string regex="{$regex}" select="/elem">
<xsl:matching-substring>
<token><xsl:value-of select="regex-group(1)"/></token>
</xsl:matching-substring>
</xsl:analyze-string>
</root>
</xsl:template>
</xsl:transform>
Output file:
<root>
<token>"foo, bar"</token>
<token>baz</token>
<token>bom</token>
</root>
