[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Writing out to and reading back from an XML file
 I posted this the other day, but made the mistake of burying the question down inside an email on another subject. Of course, it's also a summer weekend... Nevertheless, I still can't figure out a usable workaround, and I'd appreciate any insights anyone might have. Here's the situation: I have a very large file which I need to parse piece by piece, so I'm looping through <BillHeader> and <Bill> (many times) and finally <BillTrailer> elements. In each case, the XSLT is run on a single <BillHeader>, <Bill>, or <BillTrailer> rather than on the entire XML document, which could be several hundred megabytes. So far, so good, but as it turns out, the <BillTrailer> output needs to replicate most of what's in the <BillHeader> output. The solution I'm trying to use is to write out the <BillHeader> normally, but also to an XML document which can then get called back in when we get to the <BillTrailer>. The file is getting written out more or less as expected, and has the good data, but then the later process can't find the file again. The cause appears to be that my filesystem has spaces in the names (d--n that Windows!) so the file isn't getting written out to c:\Documents and Settings\ etc. but to c:\Documents%20and%20Settings etc. -- I have a complete tree built up on my C drive with all of the spaces replaced with %20s. Then the later process looks in the current directory and the file isn't there. I've tried to get the URI of the current directory as a string so I could then replace the spaces with %20s and use that as the base URI of the document() function, but wasn't able to make that work -- here's the code I tried: <xsl:variable name="header"><!-- not working --> <!--<xsl:variable name="base"> <xsl:variable name="uri"> <xsl:value-of select="document('')/invoice"/> </xsl:variable> <xsl:call-template name="translate-space"> <xsl:with-param name="base" select="string(namespace::$uri)"/> </xsl:call-template> </xsl:variable> <xsl:variable name="file"> <xsl:value-of select="concat($base,'/BillHeader.xml')"/> </xsl:variable> <xsl:value-of select="document($file)"/>--> </xsl:variable> <xsl:template name="translate-space"> <xsl:param name="base"/> <xsl:choose> <xsl:when test="contains($base,' ')"> <xsl:call-template name="translate-space"> <xsl:with-param name="base" select="concat(substring-before($base,' '),'%20',substring-after($base,' '))"/> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:value-of select="$base"/> </xsl:otherwise> </xsl:choose> </xsl:template> I was getting ClassCast exceptions, probably (I'm not sure) from the place where I try to cast the namespace as a string and then it still couldn't find the document. I also tried setting up a shortcut to the other file from the current directory but that didn't work either -- the file still wasn't found. So, I think I understand what's happening, but I don't have a way around it -- any suggestions out there? Thanks! Yours, Chris Loschen closchen@xxxxxxxxxxxxxxxxxx 781-718-3017 (cell)
