Org babel extension to apply xslt templates to xml source blocks or source block results.
#+name: my-xml-file #+begin_src nxml <?xml version="1.0" encoding="UTF-8"?> <catalog> <cd> <title>Empire Burlesque</title> <artist>Bob Dylan</artist> <country>USA</country> <company>Columbia</company> <price>10.90</price> <year>1985</year> </cd> <cd> <title>Hide your heart</title> <artist>Bonnie Tyler</artist> <country>UK</country> <company>CBS Records</company> <price>9.90</price> <year>1988</year> </cd> <cd> <title>Greatest Hits</title> <artist>Dolly Parton</artist> <country>USA</country> <company>RCA</company> <price>9.90</price> <year>1982</year> </cd> </catalog> #+end_src

The xml source is provided via the input variable in the source block header.
#+begin_src xslt :var input=(extract-src-content "my-xml-file")
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">

<table border="1">
<tr bgcolor="#9acd32">

</tr>
<xsl:for-each select="catalog/cd">

You can provide a named source block as input using the following elisp snippet.
(defun extract-src-content (name)
(save-excursion
(org-babel-goto-named-src-block name)
(org-element-property :value (org-element-at-point))))Source: https://emacs.stackexchange.com/questions/29131/get-contents-of-a-named-source-block
<html><body>
<h2>My CD Collection</h2>
<table border="1">
<tr bgcolor="#9acd32">
<th>Title</th>
<th>Artist</th>
</tr>
<tr>
<td>Empire Burlesque</td>
<td>Bob Dylan</td>
</tr>
<tr>
<td>Hide your heart</td>
<td>Bonnie Tyler</td>
</tr>
<tr>
<td>Greatest Hits</td>
<td>Dolly Parton</td>
</tr>
</table>
</body></html>Alternatively you can consume the output of, for example, an api call from a restclient source block (or any other language block that yields xml ouput) by providing the source block name (with brackets and relevant parameters) as the input variable.
#+name: my-api #+BEGIN_SRC restclient :var endpoint="localhost:8080" GET :endpoint/api?foo=bar #+END_SRC
#+begin_src xslt :var input=my-api()
