I'm converting atom xml to html but in the xml I have element that shows html and in my result I get it as text.

The XML:

<feed xmlns="http://www.w3.org/2005/Atom" xmlns:v3="urn:hl7-org:v3" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xml:base="http://apps.nlm.nih.gov/medlineplus/services/" xml:lang="es">
<title type="text">MedlinePlus Connect</title>
<subtitle type="text">MedlinePlus Connect results for ICD-9-CM 250.33</subtitle>

Para esa gente, la causa de muerte más común es una infección, como una neumonía. </p>

The XSLT:

                            </p>
                            <p>
                            <xsl:for-each     select="atom:summary">
                                    <xsl:apply-templates select="." mode="html"/>
                            </xsl:for-each>
                            </p>
                  </atom:Entry>
                </xsl:for-each>
               </atom:entries>
        </atom:Feed>
    </body>
</html>
  </xsl:template>
</xsl:stylesheet>

I wan't that the HTML inside will shown with the design and not as text

The problem is in:

        <xsl:for-each select="atom:summary">
                                <xsl:apply-templates select="." mode="html"/>
                    </xsl:for-each>
有帮助吗？

解决方案

You say the problem is with this...

  <xsl:apply-templates select="." mode="html"/>

Indeed it is! You are using the mode attribute here, but there is no template present in your XSLT that has this mode specified. Of course, you might be showing a cut-down version of your XSLT, but assuming not, what will happen in this case is that when XSLT cannot find a template that matches, its built-in templates will be used, and these will ultimately output the text within the nodes.

Try adding this template to your XSLT

<xsl:template match="*" mode="html">
   <xsl:copy-of select="." />
</xsl:template>

However, you might find when you do this, the output looks like this...

<p xmlns="http://www.w3.org/2005/Atom" class="NLMalsoCalled">Otros nombres...

This is because the elements within the summary node are part of the "http://www.w3.org/2005/Atom" namespace in the original feed. If you don't want the namespaces present, try these two templates instead

  <xsl:template match="*" mode="html">
    <xsl:element name="{local-name()}">
      <xsl:apply-templates select="@*|node()" mode="html"/>
    </xsl:element>
  </xsl:template>

  <xsl:template match="@*" mode="html">
     <xsl:copy-of select="." />
  </xsl:template>

Do note that this line in your XSLT

<xsl:for-each     select="atom:summary">
   <xsl:apply-templates select="." mode="html"/>
</xsl:for-each>

Can be replaced with just this

   <xsl:apply-templates select="atom:summary" mode="html"/>
