Don't understand which errors

metinhoclam · July 29th, 2010, 10:33 AM

My source document:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<RootNode>
    <Name>Bob</Name>
    <ContactDetails>
        <Address>
            <Line1>1 High Street</Line1>
            <Town>TownName</Town>
            <Postcode>AB1 1CD</Postcode>
        </Address>
        <Email>[email protected]</Email>
    </ContactDetails>
    <AltContactDetails>
        <Address>
            <Line1>3 Market Square</Line1>
            <Town>TownName</Town>
            <Postcode>EF2 2GH</Postcode>
        </Address>
        <Email>[email protected]</Email>
    </AltContactDetails>
</RootNode>

My transformation document:

Code:

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions">
	<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
	<xsl:template match="/">
		<xsl:apply-templates/>
	</xsl:template>

	<xsl:template match="RootNode">
	  <PersonsName>
		<xsl:value-of select="Name"/>
	  </PersonsName>
	  <xsl:apply-templates select="ContactDetails|AltContactDetails" />
	</xsl:template>

<xsl:template match="ContactDetails|AltContactDetails">
  <xsl:copy>
    <FirstLine>
      <xsl:value-of select="Address/Line1"/>
    </FirstLine>
    <Town>
      <xsl:value-of select="Address/Town"/>
    </Town>
    <PostalCode>
      <xsl:value-of select="Address/Postcode"/>
    </PostalCode>
  </xsl:copy>
</xsl:template>
</xsl:stylesheet>

And the error message look like this:
Only one top level element is allowed in an XML document. Error processing resource

Anybody help me find out the errors?
Thanks,

That is an error message the XML parser gives, not the XSLT processor. So either your XML or your stylesheet is not a well-formed XML document with a single root element. Your posted samples seem fine however so somehow you are processing different documents when you get the error.

samjudson · July 29th, 2010, 10:42 AM

The error is in your output XML - which isn't a valid XML document.

Code:

<PersonName>
...
</PersonName>
<ContactDetails>
...
</ContactDetails>
<AltContactDetails>
...
</AltContactDetails>

You need to wrap the whole XML fragment in another XML element (e.g. like RootNode in your input XML) or put the contact details inside the PersonName.

I knew the Name is the same level with ContactDetails, AltContactDetails. And I've already checked these documents a lot of time...I didnot see any errors....please give me your solution for my xslt...the source file was file...i think..I'm using Altova XML spy to run these files...

samjudson · July 29th, 2010, 11:11 AM

You cannot have Name at the same level as ContactDetails without an outer XML element.

Code:

<RootNode>
  <PersonName>
  ...
  </PersonName>
  <ContactDetails>
  ...
  </ContactDetails>
  <AltContactDetails>
  ...
  </AltContactDetails>
</RootNode>

What you want to call this element is up to you.

I have change the source file:
<?xml version="1.0" encoding="UTF-8"?>
<RootNode>
<Name>
BOB
<ContactDetails>
<Address>
<Line1>1 High Street</Line1>
<Town>TownName</Town>
<Postcode>AB1 1CD</Postcode>
</Address>
<Email>[email protected]</Email>
</ContactDetails>
<AltContactDetails>
<Address>
<Line1>3 Market Square</Line1>
<Town>TownName</Town>
<Postcode>EF2 2GH</Postcode>
</Address>
<Email>[email protected]</Email>
</AltContactDetails>
</Name>
</RootNode>

But I got the unexpected result...
--------------
<?xml version="1.0" encoding="UTF-8" ?>
<PersonsName xmlns:fn="http://www.w3.org/2005/xpath-functions" xmlns:xs="http://www.w3.org/2001/XMLSchema">BOB 1 High StreetTownNameAB1 [email protected]3 Market SquareTownNameEF2 [email protected]</PersonsName>

I usually encounter with the same problem with match template like this..how can i get the result with the tag...
Need your help! Thanks

Why is this result unexpected? You did <xsl:value-of select="Name"/>, which gives you the string value of the Name element, that is, all the text inside the Name element. What result did you expect, if not this? (And why did you change the source document to something so strange?)

samjudson · July 30th, 2010, 01:39 AM

To fix your problem you don't need to change your input XML, but the output XML. To do this you need to add a root node to the output you are generating in your XSLT - something like this:

Code:

<xsl:template match="RootNode">
    <RootNode>
        <PersonsName>
            <xsl:value-of select="Name"/>
        </PersonsName>
        <xsl:apply-templates select="ContactDetails|AltContactDetails" />
    </RootNode>
</xsl:template>

I misunderstood about the xsl:apply-templates and select...I thought if select like that, then it just returns one value...
Thank,
