## Description

The EXmlDocument class wraps creation of XML documents.

## Functions

### e_xml_document_new ()

    EXmlDocument *
    e_xml_document_new (const gchar *ns_href,
                        const gchar *root_element);

Creates a new EXmlDocument with root element `root_element` and optionally also with set default namespace `ns_href` .

#### Parameters

ns_href | default namespace href to use, or `NULL`. | [nullable]
root_element | root element name |

#### Returns

a new EXmlDocument; free it with `g_object_unref()`, when no longer needed.

[transfer full]

Since: 3.26

### e_xml_document_get_xmldoc ()

    xmlDoc *
    e_xml_document_get_xmldoc (EXmlDocument *xml);

#### Parameters

xml | an EXmlDocument |

#### Returns

Underlying xmlDocPtr.

[transfer none]

Since: 3.26

### e_xml_document_get_content ()

    gchar *
    e_xml_document_get_content (const EXmlDocument *xml,
                                gsize *out_length);

Gets content of the `xml` as string. The string is nul-terminated, but if `out_length` is also provided, then it doesn't contain this additional nul character.

#### Parameters

xml | an EXmlDocument |
out_length | optional return location for length of the content, or `NULL`. | [out][nullable]

#### Returns

Content of the `xml` as newly allocated string. Free it with `g_free()`, when no longer needed.

[transfer full]

Since: 3.26

### e_xml_document_add_namespaces ()

    void
    e_xml_document_add_namespaces (EXmlDocument *xml,
                                   const gchar *ns_prefix,
                                   const gchar *ns_href,
                                   ...);

Adds one or more namespaces to `xml` , which can be referenced later by `ns_href` . The caller should take care that neither used `ns_prefix` , nor `ns_href` , is already used by `xml` .

#### Parameters

xml | an EXmlDocument |
ns_prefix | namespace prefix to use for this namespace |
ns_href | namespace href |
... | `NULL`-terminated pairs of (ns_prefix, ns_href) |

                                  const gchar *name);

Starts a new non-text element as a child of the current element. Each such call should be ended with corresponding `e_xml_document_end_element()`. Use `NULL` `ns_href` , to use the default namespace, otherwise either previously added namespace with the same href from `e_xml_document_add_namespaces()` is picked, or a new namespace with generated prefix is added.

To start a text node use `e_xml_document_start_text_element()`.

#### Parameters

xml | an EXmlDocument |
ns_href | optional namespace href for the new element, or `NULL`. | [nullable]
name | name of the new element |

Since: 3.26

### e_xml_document_start_text_element ()

                                       const gchar *name);

Starts a new text element as a child of the current element. Each such call should be ended with corresponding `e_xml_document_end_element()`. Use `NULL` `ns_href` , to use the default namespace, otherwise either previously added namespace with the same href from `e_xml_document_add_namespaces()` is picked, or a new namespace with generated prefix is added.

To start a non-text node use `e_xml_document_start_element()`.

#### Parameters

xml | an EXmlDocument |
ns_href | optional namespace href for the new element, or `NULL`. | [nullable]
name | name of the new element |

Since: 3.26

### e_xml_document_end_element ()

    void
    e_xml_document_end_element (EXmlDocument *xml);

This is a pair function for `e_xml_document_start_element()` and `e_xml_document_start_text_element()`, which changes current element to the parent of that element.

#### Parameters

xml | an EXmlDocument |

Since: 3.26

                                  const gchar *value);

Adds a new attribute to the current element. Use `NULL` `ns_href` , to use the default namespace, otherwise either previously added namespace with the same href from `e_xml_document_add_namespaces()` is picked, or a new namespace with generated prefix is added.
