Question

XML NODE

 <!-- url path="/jsp/Admin_BetaSignup.jsp" roles="ZohoCampaignAdmin" authentication="optional" description="Page used to add the Beta users">
        <param name="zuid" xss="throwerror" max-len="300"/>
</url -->

I Want to select this node via xpath . I use below code in java .

Document document = DocumentBuilderFactory.newInstance()
    .newDocumentBuilder()
    .parse("/home/local/ZOHOCORP/bharathi-1397/build/AdventNet/Sas/webapps/zcadmin/WEB-INF/security.xml");
XPath xpath = XPathFactory.newInstance().newXPath();
System.out.println(
    xpath.evaluate("//comment()[@path='/jsp/Admin_BetaSignup.jsp']",
    document,XPathConstants.NODE)
);

Output : null .

Why?

Use:

//comment()[contains(., 'path="/jsp/Admin_BetaSignup.jsp"')]

XSLT – based verification:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="/">
     <xsl:copy-of select=
     "//comment()
         [contains(., 'path=&quot;/jsp/Admin_BetaSignup.jsp&quot;')]
    "/>
 </xsl:template>
</xsl:stylesheet>

when this transformation is applied on the XML document below:

<!-- url path="/jsp/Admin_BetaSignup.jsp" roles="ZohoCampaignAdmin" authentication="optional" description="Page used to add the Beta users">         <param name="zuid" xss="throwerror" max-len="300"/> </url -->
<t>
 <!-- Another comment -->
</t>

the wanted comment node is selected and copied to the output:

<!-- url path="/jsp/Admin_BetaSignup.jsp" roles="ZohoCampaignAdmin" authentication="optional" description="Page used to add the Beta users">         <param name="zuid" xss="throwerror" max-len="300"/> </url -->
