Convert xml with xslt

I have the following xml:

<fo:block font-weight="bold" font-style="italic">Some Text Here</fo:block>

I need to convert it to the following using xsl:

{\b\iSome Text Here\i0\b0\par}

So far I have managed to select a block element using:

<xsl:template match="fo:block">
<xsl:text>{</xsl:text>
    <xsl:apply-templates />
<xsl:text>\par}</xsl:text></xsl:template>

and I output: {Some Text Here\par}

I struggle with attributes and insert them using xsl, can someone give me an example of choosing these attributes and getting the desired result?

Here's a fairly simple way to do this in general terms using template modes and instructions <xsl:sort>.

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="fo:block">
  <xsl:text>{</xsl:text>
  <xsl:apply-templates select="@*" mode="prefix" />
  <xsl:apply-templates select="node()" />
  <xsl:apply-templates select="@*" mode="suffix">
    <xsl:sort order="descending"/>
  </xsl:apply-templates>
  <xsl:text>\par}</xsl:text>
</xsl:template>

<xsl:template match="@font-weight['bold']" mode="prefix">\b</xsl:template>
<xsl:template match="@font-style['italic']" mode="prefix">\i</xsl:template>

<xsl:template match="@font-weight['bold']" mode="suffix">\b0</xsl:template>
<xsl:template match="@font-style['italic']" mode="suffix">\i0</xsl:template>

</xsl:stylesheet>

<xsl:sort order="descending" /> processes the attributes in reverse the second time the suffix mode is used.

Strictly speaking, select="node()"in the middle of the main template is redundant, but it makes it clearer when it reads that only nodes are processed, not attributes.

, suffix :

<xsl:template match="@*" mode="suffix">
  <xsl:apply-templates select="." mode="prefix" />
  <xsl:text>0</xsl:text>
</xsl:template>

        <xsl:if test="@font-weight = 'bold'">\b</xsl:if>
        <xsl:if test="@font-style = 'italic'">\i</xsl:if>

        <xsl:apply-templates />

        <xsl:if test="@font-style = 'italic'">\i0</xsl:if>
        <xsl:if test="@font-weight = 'bold'">\b0</xsl:if>
    <xsl:text>\par}</xsl:text>
</xsl:template/>
