Question: I'm trying to transform some *XML* into *HTML* using *XSLT*. 

**Problem:**

I can't get it to work. Can someone tell me what I'm doing wrong?

**XML:**

```
<ArrayOfBrokerage xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.test.com/">
    <Brokerage>
        <BrokerageID>91</BrokerageID>
        <LastYodleeUpdate>0001-01-01T00:00:00</LastYodleeUpdate>
        <Name>E*TRADE</Name>
        <Validation i:nil="true" />
        <Username>PersonalTradingTesting</Username>
    </Brokerage>
</ArrayOfBrokerage>

```

**XSLT:**

```
<xsl:stylesheet version="1.0" xmlns="http://www.test.com/" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xslFormatting="urn:xslFormatting">

    <xsl:output method="html" indent="no"/>

    <xsl:template match="/ArrayOfBrokerage">
        <xsl:for-each select="Brokerage">
            Test
       </xsl:for-each>
    </xsl:template>

</xsl:stylesheet>

```

Answer: 
You need to provide a namespace prefix in your xslt for the elements you are transforming. For some reason (at least in a Java JAXP parser) you can't simply declare a default namespace. This worked for me:

```
<xsl:stylesheet version="1.0" xmlns:t="http://www.test.com/" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xslFormatting="urn:xslFormatting">

    <xsl:output method="html" indent="no"/>

    <xsl:template match="/t:ArrayOfBrokerage">
        <xsl:for-each select="t:Brokerage">
            Test
        </xsl:for-each>
    </xsl:template>

</xsl:stylesheet>

```

This will catch everything that is namespaced in your XML doc.
How do you execute the transformation? Maybe you forgot to link the XSLT stylesheet to XML document using:

```
<?xml-stylesheet type="text/xsl" href="cdcatalog.xsl"?>

```

at the beginning of XML document. [More explanation here](http://www.w3schools.com/xsl/xsl_transformation.asp).
