xmlns in root element

[Former Member]

When converting exchange rates xml from http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml

I'm getting problem with xmlns in root element.

CALL TRANSFORMATION triggers CX_XSLT_ABAP_CALL_ERROR, but only if there is xmlns attribute in first line in input xml:

<gesmes:Envelope xmlns:gesmes="http://www.gesmes.org/xml/2002-08-01" xmlns="http://www.ecb.int/vocabulary/2002-08-01/eurofxref">

Without this xmlns=..... (or when modifying e.g. abcxmlns= ) works following xslt fine:

<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:sap="http://www.sap.com/sapxsl" version="1.0">

<xsl:strip-space elements="*"/>

<xsl:template match="/">

<xsl:copy>

<xsl:apply-templates/>

</xsl:copy>

</xsl:template>

<xsl:template match="Cube/Cube">

<asx:abap xmlns:asx="http://www.sap.com/abapxml" version="1.0">

<asx:values>

<ROOT2>

<xsl:value-of select="@time"/>

</ROOT2>

<ROOT1>

<xsl:apply-templates select="Cube"/>

</ROOT1>

</asx:values>

</asx:abap>

</xsl:template>

<xsl:template match="Cube/Cube/Cube">

<loop>

<AMOUNT>

<xsl:value-of select="1"/>

</AMOUNT>

<CCYCODE>

<xsl:value-of select="@currency"/>

</CCYCODE>

<VALUE>

<xsl:value-of select="@rate"/>

</VALUE>

</loop>

</xsl:template>

</xsl:transform>

I'd appreciate if someone migh advise me how to alternate the xslt or tell me what the xmlns in input does.

Cheers

If a namespace is specified on root level, it propagates down to all children, see:

http://www.w3.org/TR/REC-xml-names/

The namespace is part of a name. So, if you have an element <Cube> as child of the root element <root xmlns="http://www.gesmes.org/xml/2002-08-01">, then

<xsl:apply-templates select="Cube"/>

won't be applied, since the qualified name of the element is not Cube but {http://www.gesmes.org/xml/2002-08-01}Cube

If you want the XSLT to work with and without namespace equally well, you have to work with local names in XPath expressions:

<xsl:apply-templates select="local-name() = 'Cube'"/>

The same holds for all XPath functions working with element names.

Usually, however, the namespace is part of the contract with the client and is

• either obligatory to be used
• or obligatory to be omitted.

But not both.
