Even though my approach works, I recommend using Scrutinizer's approach because it will be way much faster than using a while loop and feeding input to awk

xmerl_xs
xmerl_xs(3erl) Erlang Module Definition xmerl_xs(3erl)
NAME
xmerl_xs -
Erlang has similarities to XSLT since both languages
have a functional programming approach.
DESCRIPTION
Erlang has similarities to XSLT since both languages have a functional programming approach. Using xmerl_xpath it is possible to write XSLT
like transforms in Erlang.
XSLT stylesheets are often used when transforming XML documents, to other XML documents or (X)HTML for presentation. XSLT contains quite
many functions and learning them all may take some effort. This document assumes a basic level of understanding of XSLT.
Since XSLT is based on a functional programming approach with pattern matching and recursion it is possible to write similar style sheets
in Erlang. At least for basic transforms. This document describes how to use the XPath implementation together with Erlangs pattern match-
ing and a couple of functions to write XSLT like transforms.
This approach is probably easier for an Erlanger but if you need to use real XSLT stylesheets in order to "comply to the standard" there is
an adapter available to the Sablotron XSLT package which is written i C++. See also the Tutorial .
EXPORTS
built_in_rules(Fun, E) -> List
The default fallback behaviour. Template funs should end with:
template(E) -> built_in_rules(fun template/1, E) .
select(String::string(), E) -> E
Extracts the nodes from the xml tree according to XPath.
See also: value_of/1 .
value_of(E) -> List
Types E = unknown()
Concatenates all text nodes within the tree.
Example:
<xsl:template match="title">
<div align="center">
<h1><xsl:value-of select="." /></h1>
</div>
</xsl:template>
becomes:
template(E = #xmlElement{name='title'}) ->
["<div align="center"><h1>",
value_of(select(".", E)), "</h1></div>"]
xslapply(Fun::Function, EList::list()) -> List
Types Function = () -> list()
xslapply is a wrapper to make things look similar to xsl:apply-templates.
Example, original XSLT:
<xsl:template match="doc/title">
<h1>
<xsl:apply-templates/>
</h1>
</xsl:template>
becomes in Erlang:
template(E = #xmlElement{ parents=[{'doc',_}|_], name='title'}) ->
["<h1>",
xslapply(fun template/1, E),
"</h1>"];
