How do I excluding nodes from XLST - xslt

Sorry, this is a really novice question. My real problem involves translating HTML to Open Office XML, but this illustrates the issue I am seeing. I want to make sure the "b" node is ignored in my processing, i.e. not get the 123 at the end of the results output.
XML:
<?xml version="1.0"?><?xml-stylesheet type="text/xsl"?>
<a>
<hello-world>
<greeter>An XSLT Programmer</greeter>
<greeting>Hello, World!</greeting>
</hello-world>
<b>123
</b>
</a>
XSLT:
<?xml version="1.0"?><xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="hello-world">
<HTML><HEAD><TITLE></TITLE></HEAD><BODY><H1>
<xsl:value-of select="greeting"/>
</H1>
<xsl:apply-templates select="greeter"/>
</BODY></HTML>
</xsl:template>
<xsl:template match="greeter">
<DIV>from <I><xsl:value-of select="."/></I></DIV>
</xsl:template>
</xsl:stylesheet>
Results:
<HTML>
<HEAD>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<TITLE></TITLE>
</HEAD>
<BODY>
<H1>Hello, World!</H1>
<DIV>from <I>An XSLT Programmer</I></DIV>
</BODY>
</HTML>
123

I see you added an answer, but thought I could add more information.
Your first attempt was good, you could have simply added another template to ignore the "b" nodes.
<xsl:template match="b"/>
What was happening is that the XSLT built-in template rules include by default a template that copies the text of any node that's not explicitely matched by your templates.
Reference: docstore.mik.ua/orelly/xml/xmlnut/ch08_07.htm
See the output of your transformation with the added template: https://xsltfiddle.liberty-development.net/aixRus

The issue was that I wasn't selecting the whole document to begin with. If I change the xslt as follows, it then works
<?xml version="1.0"?><xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/*">
<xsl:apply-templates select='hello-world'/>
</xsl:template>
<xsl:template match="hello-world">
<HTML><HEAD><TITLE></TITLE></HEAD><BODY><H1>
<xsl:value-of select="greeting"/>
</H1>
<xsl:apply-templates select="greeter"/>
</BODY></HTML>
</xsl:template>
<xsl:template match="greeter">
<DIV>from <I><xsl:value-of select="."/></I></DIV>
</xsl:template>
</xsl:stylesheet>

copy-of with search and replace relative paths

I want to insert an html snippet from an external file into my output document with copy-of like described here: https://stackoverflow.com/a/5976762/18427492
The html snipped is a navigation bar and also used by other (python) scripts to generate other html files.
I need to replace the path in "href" to match a relative path that i have in a XSLT variable.
Full file content (Template file to be copied):
<ul class="nav">
<li class="fineprint">MyNiceGame Developer Mode Documentation</li>
<li class="switchlang"><img src="/deco/dco_en_sml.gif" alt="English" border="0"></img></li>
<li>Introduction</li>
<li>Contents</li>
<li>Search</li>
<li>Engine</li>
<li>Command Line</li>
<li>Game Data</li>
<li>Script</li>
</ul>
So how can i insert this snippet into my XSL document and replace ../../sdk/ (its possible to change this string to something like {replace-me}/sdk/...) with a relative path that i already have in a XSLT variable?
My XSLT document (i want to replace the <xsl:call-template name="nav"/> with the template file processing):
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" version="3.0" xpath-default-namespace="https://clonkspot.org" exclude-result-prefixes="xs">

doctype-system="http://www.w3.org/TR/html4/strict.dtd"/>
<xsl:template match="/clonkDoc">
<html>
<body>
<xsl:call-template name="nav"/>
<xsl:apply-templates select="func"/>
<!-- other possible nodes under /clonkDoc -->
<xsl:call-template name="nav"/>
</body>
</html>
</xsl:template>
<xsl:template name="nav">
<xsl:param name="relpath" tunnel="yes"/>
<ul class="nav">
<li class="fineprint">
<xsl:when test='lang("en")'>>MyNiceGame Developer Mode Documentation</xsl:when>
</li>
<!-- Other li elements -->
</xsl:template>
Example source file:
<?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>
<?xml-stylesheet type="text/xsl" href="../../../clonk.xsl"?>
<clonkDoc xmlns="https://clonkspot.org"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="https://clonkspot.org ../../../clonk.xsd" xml:lang="de">
<func>
<!-- other nodes -->
</func>
</clonkDoc>
Desired target file:
<!DOCTYPE html
PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<!-- stuff -->
</head>
<body>
<ul class="nav">
<!-- The corrected li elements with modified a href link -->
</ul>
<!-- Other stuff from source file (<func>) -->
<ul class="nav">
<!-- The corrected li elements with modified a href link -->
</ul>
</body>
</html>
Martin Honnen's solution for my specific case with the xpath-default-namespace:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" version="3.0" xpath-default-namespace="https://clonkspot.org" exclude-result-prefixes="xs">
<xsl:output method="html" encoding="ISO-8859-1" doctype-public="-//W3C//DTD HTML 4.01//EN"
doctype-system="http://www.w3.org/TR/html4/strict.dtd"/>
<xsl:template match="/clonkDoc">
<html>
<body>
<xsl:apply-templates select="doc('file.html')//ul[#class = 'nav']" xpath-default-namespace="" mode="fix-links"/>
<xsl:apply-templates select="func"/>
<!-- other possible nodes under /clonkDoc -->
<xsl:apply-templates select="doc('file.html')//ul[#class = 'nav']" xpath-default-namespace="" mode="fix-links"/>
</body>
</html>
</xsl:template>
<xsl:mode name="fix-links" on-no-match="shallow-copy"/>
<xsl:template mode="fix-links" match="ul/li/a/#href" xpath-default-namespace="">
<xsl:message>Value href: <xsl:value-of select="."></xsl:value-of></xsl:message>
<xsl:attribute name="{name()}" select="replace(., '../../sdk', 'foobar')"/>
</xsl:template>
copy-of makes a a deep copy, if you want to transform input nodes (even only their attribute values) you write templates to do so e.g. <xsl:apply-templates select="doc('file.xml')//ul[#class = 'nav']" mode="fix-links"/>, or, perhaps, as the edit says the snippet with the ul is all in the file, use simply <xsl:apply-templates select="doc('file.xml')" mode="fix-links"/>, and
<xsl:mode name="fix-links" on-no-match="shallow-copy"/>
<xsl:template mode="fix-links" match="ul/li/a/#href">
<xsl:attribute name="{name()}" select="replace(., '../../sdk', $varname)"/>
</xsl:template>
The xsl:mode declaration is XSLT 3 only, in earlier versions declare the identity transformation for that mode e.g.
<xsl:template mode="fix-links" match="#* | node()">
<xsl:copy>
<xsl:apply-templates select="#* | node()" mode="fix-links"/>
</xsl:copy>
</xsl:template>
in XSLT 1 or
<xsl:template mode="fix-links" match="#* | node()">
<xsl:copy>
<xsl:apply-templates select="#* | node()" mode="#current"/>
</xsl:copy>
</xsl:template>
in XSLT 2.
XSLT 3 sample (slighly adapted for the demonstration to work with the primary input) outputs
<ul class="nav">
<li class="fineprint">MyNiceGame Developer Mode Documentation</li>
<li class="switchlang"><img src="/deco/dco_de_sml.gif" alt="German" border="0"/></li>
<li>Introduction</li>
<li>Contents</li>
<li>Search</li>
<li>Engine</li>
<li>Command Line</li>
<li>Game Data</li>
<li>Script</li>
</ul>
As for the information in the latest edit that the secondary input document you want to process has elements in no namespace but your primary one has elements in a certain namespace that your XSLT has used as the xpath-default-namespace, in that case you need to override that for any selections in the secondary input e.g.
<xsl:mode name="fix-links" on-no-match="shallow-copy"/>
<xsl:template mode="fix-links" match="ul/li/a/#href" xpath-default-namespace="">
<xsl:attribute name="{name()}" select="replace(., '../../sdk', $varname)"/>
</xsl:template>
and if you continue to use the apply-templates with an element selector, there as well e.g. <xsl:apply-templates select="doc('file.xml')//ul[#class = 'nav']" xpath-default-namespace="" mode="fix-links"/>.

XSL embed original XML file

I am transforming XML files with XSL to HTML files. Is it possible to embed the original XML file in the HTML output? When yes, how is that possible?
Update 1: To make my need better understandable: In my HTML file, I want a form where I can download the original XML file. Therefore I have to embed the original XML file into my HTML file (e.g. as a hidden input field)
Thanks
If you want to copy the nodes through you can simply do <xsl:copy-of select="/"/> where you want to insert them, however, putting arbitrary XML nodes into HTML does not make sense usually. If you want to serialize an XML document to plain text to render it then you can use solutions like http://lenzconsulting.com/xml-to-string/, for instance:
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:import href="http://lenzconsulting.com/xml-to-string/xml-to-string.xsl"/>
<xsl:output method="html" doctype-public="XSLT-compat" omit-xml-declaration="yes" encoding="UTF-8" indent="yes" />
<xsl:template match="/">
<html>
<head>
<title>Test</title>
</head>
<body>
<section>
<h1>Test</h1>
<xsl:apply-templates/>
<section>
<h2>Source</h2>
<pre>
<xsl:apply-templates mode="xml-to-string"/>
</pre>
</section>
</section>
</body>
</html>
</xsl:template>
<xsl:template match="data">
<ul>
<xsl:apply-templates/>
</ul>
</xsl:template>
<xsl:template match="item">
<li>
<xsl:apply-templates/>
</li>
</xsl:template>
</xsl:transform>
transforms an XML input like
<data>
<item att="value">
<!-- comment -->
<foo>bar</foo>
</item>
</data>
into the HTML
<!DOCTYPE html
PUBLIC "XSLT-compat">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Test</title>
</head>
<body>
<section>
<h1>Test</h1>
<ul>
<li>
bar
</li>
</ul>
<section>
<h2>Source</h2><pre><data>
<item att="value">
<!-- comment -->
<foo>bar</foo>
</item>
</data></pre></section>
</section>
</body>
</html>

XSLT: Iterating through all value of a xsl:key map

XML
<books>
<book title="XML Today" author="David Perry" release="2016"/>
<book title="XML and Microsoft" author="David Perry" release="2015"/>
<book title="XML Productivity" author="Jim Kim" release="2015"/>
</books>
The following XSL code iterates through all books by David Perry.
XSL
<xsl:key name="title-search" match="book" use="#author"/>
<xsl:template match="/">
<HTML>
<BODY>
<xsl:for-each select="key('title-search', 'David Perry')">
<DIV>
<xsl:value-of select="#title"/>
</DIV>
</xsl:for-each>
</BODY>
</HTML>
</xsl:template>
HTML output
<HTML>
<BODY>
<DIV>XML Today</DIV>
<DIV>XML and Microsoft</DIV>
</BODY>
</HTML>
Now I would like to iterate not only through all books by David Perry but through all books by any author.
How would a corresponding outer loop look like?
Or in other words: How do I iterate through all values of my title-search key.
The output should be something like this:
<HTML>
<BODY>
<H1>David Perry</H1>
<DIV>XML Today</DIV>
<DIV>XML and Microsoft</DIV>
<H1>Jim Kim</H1>
<DIV>XML Productivity</DIV>
</BODY>
</HTML>
This should do the job:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:key name="title-search" match="book" use="#author"/>
<xsl:template match="/books">
<HTML>
<BODY>
<xsl:apply-templates select="book" />
</BODY>
</HTML>
</xsl:template>
<xsl:template match="book">
<xsl:variable name="author" select="#author" />
<xsl:if test="generate-id(.) = generate-id(key('title-search', $author)[1])">
<H1><xsl:value-of select="#author" /></H1>
<xsl:apply-templates select="//book[#author = $author]" mode="titles"/>
</xsl:if>
</xsl:template>
<xsl:template match="book" mode="titles">
<DIV>
<xsl:value-of select="#title"/>
</DIV>
</xsl:template>
</xsl:stylesheet>
It uses a technique called Muenchian grouping. Each element in an XML document implicitly has a unique ID assigned to it by the XSLT processor (it can also be explicitly assigned with the id attribute in the document itself). This part:
generate-id(.) = generate-id(key('title-search', $author)[1])
basically tests if the ID of the current book element is the same as that of the first book element with the same author. The variable $author is taken from the current book, The key is used to look up the <book> elements with that same author, the [1] predicate takes the first one. As a result, the <H1> is only generated for the first occurrence of that specific author, and in that same if element we're then applying the template for listing the books of that author. The mode is used to avoid a clash between these templates. There's no doubt a solution that doesn't use modes, but this works too. You could also do a lot of this with <xsl:for-each> but I made separate templates because XSLT is declarative and works best when treating it as such.
Grouping is a lot easier in XSLT 2, but when stuck with XSLT 1, the Muenchian grouping technique often provides a solution once you grok it.
Try this:
XSLT2:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<HTML>
<BODY>
<xsl:for-each-group select="books/book" group-by="#author">
<H1><xsl:value-of select="current-grouping-key()"/></H1>
<xsl:for-each select="current-group()">
<DIV><xsl:value-of select="#title"/></DIV>
</xsl:for-each>
</xsl:for-each-group>
</BODY>
</HTML>
</xsl:template>
</xsl:stylesheet>

I want to add an attribute "onclick" on "here" in a CDATA and getting the whole "mail" node? Is it really possible? Can anyone help me with this stuff? Thanks in advance.
Your help would be greatly appreciated :)
There are no nodes or tags inside a CDATA section. CDATA means "character data". The only reason for putting stuff inside CDATA is to say "The stuff in here might look like markup, but I don't want it treated as markup; just treat it as text". So if you want to treat it as markup, don't put it in CDATA.
You'll have to resort to string manipulation, like so:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="body[contains(.,'>here</a>')]">
<xsl:value-of disable-output-escaping="yes" select="concat(
'<![CDATA[',
substring-before(.,'>here</a>'),
' onclick="myfunction();">here</a>',
substring-after(.,'>here</a>'),
']]>'
)"/>
</xsl:template>
</xsl:stylesheet>
But is there a reason why the mail body has to be CDATA in the first place?

Explanation:
The identity rule copies every node "as-is".
It is overriden by two templates. The first ignores/deletes every body element`.
The second template overriding the identity template also overrides the first such template (that deletes every body element) for any body element that is the first body child of its parent. For this first body child only, a body element is generated and in its body all nodes that are children nodes of any body child of its parent (the current body elements and all of its body siblings) are processed.
<xsl:template match="Content">
<body>
<xsl:apply-templates select="body/text"/>
</body>
</xsl:template>
<xsl:template match="body/text">
<xsl:copy>
<xsl:apply-templates select="#* | node()"/>
</xsl:copy>
</xsl:template>
