How can I get tag's text value with xsl transformation

I have a XML like this 

<Error>An error has occured while saving the workflow
    <ErrorFile>C:\temp\Log\ErrorImages\accountwf38_1401351602333.png</ErrorFile>
</Error>

when I write an XSL transformation like this

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

I am getting the entire error value as output, including the error file value. But I need only An error has occured while saving the workflow as output. How can I write a transformation for that?

Thanks

The <Error> element has three child nodes. A text node, an element (ErrorFile) node and another text node (containing a new line and some spaces before the end tag)`.

The XPath expression you used selects the entire Error node, which is converted to its string value when used in <xsl:value-of>, which consists of of all of its descendants converted to string.

To obtain what you need you can use this expression:

<xsl:value-of select="Error/text()"/>

which will select only the child text nodes.

And you can get rid of the unnecessary spaces using:

    <xsl:value-of select="normalize-space(Error/text())"/>
